The Thought
What occurs if you mix a grayscale picture, a coloured picture, and a lens impact that follows the mouse? On this tutorial, we are going to construct a mouse-following sq. lens impact utilizing Three.js and GLSL.
The impact layers two photos: a grayscale picture covers the display screen, whereas a shade picture is revealed by means of a sq. space that follows the mouse pointer. Inside this sq., we add a lens distortion and a radial RGB shift, whereas the grayscale picture has its personal refined wave and noise-like movement.
Though the ultimate end result appears pretty advanced, the impact is constructed from a small variety of easy items. We’ll create the sq. masks, maintain it sq. whatever the viewport dimension, apply the lens and RGB shift results within the fragment shader, and easily animate the sq. because it follows the mouse. We may also add a GUI in order that the totally different parameters might be adjusted in actual time.
The thought for this undertaking got here whereas I used to be looking Pinterest and located a design the place a part of a grayscale picture seems to be minimize out by a coloured sq. with a lens impact. You may see the unique reference right here. It appeared like one thing that could possibly be recreated with WebGL, and I believed the end result could be much more fascinating if the sq. adopted the mouse and the foreground grayscale picture had a separate impact. So I made a decision to recreate it with Three.js and GLSL.
What We’re Constructing
The ultimate impact consists of the next components:
- A grayscale picture masking your entire display screen
- A shade picture seen solely contained in the sq.
- A CC Lens-style distortion that bulges outward from the middle of the sq.
- An RGB shift that turns into stronger towards the sides of the sq.
- A sq. masks that continues to be sq. whatever the display screen dimension
- Easy mouse interplay with a slight delay
- Wave and random distortion utilized to the grayscale picture
- A GUI for adjusting the parameters in actual time
Though the end result might look just a little advanced, it doesn’t use post-processing with a render goal or any 3D fashions. As an alternative, we create your entire impact inside a fraction shader by combining the weather above.

The category construction is pretty standard, so this text focuses totally on the fragment shader implementation.
Setting Up the Stage
Allow us to start with the Stage class. This class creates the scene, digicam, renderer, and different necessities for working with Three.js, and units up rendering and resize dealing with. Most of it’s normal, however one element price explaining is how the digicam’s Z place is ready.
Setting the Digicam’s Z Place
The digicam’s Z place is ready utilizing a perform known as calcViewportDistance.
const calcViewportDistance = (top: quantity, fov: quantity): quantity => {
return top / (2 * Math.tan((fov * Math.PI) / 360))
}With out going into the mathematical particulars, this calculation finds the gap at which the seen top of the digicam matches top. By scaling a 1 x 1 airplane to the viewport width and top, your entire mesh suits exactly inside the digicam’s area of view (FOV).
The Mesh Class
Subsequent, allow us to briefly have a look at the Mesh class. It handles every thing associated to the mesh, together with window sizing, texture loading, mesh creation with geometry and materials, mesh sizing, and uniform administration and updates. Just like the Stage class, its construction is pretty normal, so from right here we are going to construct the ultimate look step-by-step by means of the shader implementation.
The Vertex Shader
As a result of this impact doesn’t deform any vertices, the vertex shader is easy: it passes the geometry’s UV coordinates to the fragment shader and transforms the airplane’s vertex positions into screen-space coordinates that account for the mesh scale, digicam place, FOV, and associated settings.
precision highp float;
attribute vec3 place;
attribute vec2 uv;
uniform mat4 modelViewMatrix;
uniform mat4 projectionMatrix;
various vec2 v_uv;
void most important() {
v_uv = uv;
gl_Position = projectionMatrix * modelViewMatrix * vec4(place, 1.0);
}The Fragment Shader
Displaying the Textures Fullscreen
Now allow us to transfer on to the fragment shader. We’ll start by displaying the 2 photos used on this impact throughout the total display screen. The next code within the Mesh class’s setTexture methodology masses them: texture1 is the colour picture proven contained in the sq., whereas texture2 is the grayscale picture proven throughout the realm exterior it.
const loader = new TextureLoader()
const texture1Path = this.$goal.dataset.texture1Path
const texture2Path = this.$goal.dataset.texture2Path
if (!texture1Path || !texture2Path) return
const [texture1, texture2] = await Promise.all([
loader.loadAsync(texture1Path),
loader.loadAsync(texture2Path)
])
this.uniforms.u_texture1.worth = texture1
this.uniforms.u_texture2.worth = texture2
this.uniforms.u_textureSize1.worth.set(
texture1.picture.width,
texture1.picture.top
)
this.uniforms.u_textureSize2.worth.set(
texture2.picture.width,
texture2.picture.top
)Within the fragment shader, we pattern colours from each photos (textures) and first verify that every one fills the display screen. The 2 photos used right here have the identical facet ratio, so u_textureSize1 and u_textureSize2 could possibly be mixed right into a single worth. Nonetheless, we calculate them individually utilizing every texture’s dimensions to assist photos with totally different facet ratios as nicely.
precision highp float;
uniform sampler2D u_texture1;
uniform sampler2D u_texture2;
uniform vec2 u_meshSize;
uniform vec2 u_textureSize1;
uniform vec2 u_textureSize2;
various vec2 v_uv;
#embody "../chunks/coverUv.glsl"
void most important() {
vec2 texture1Uv = getCoverUv(v_uv, u_meshSize, u_textureSize1);
vec2 texture2Uv = getCoverUv(v_uv, u_meshSize, u_textureSize2);
vec4 insideColor = texture2D(u_texture1, texture1Uv);
vec4 outsideColor = texture2D(u_texture2, texture2Uv);
gl_FragColor = insideColor;
}The getCoverUv perform used right here prevents the picture from stretching when its facet ratio differs from the viewport. Somewhat than utilizing v_uv instantly, it creates UV coordinates that protect the picture’s facet ratio and crop it from the middle, similar to CSS background-size: cowl.
vec2 getCoverUv(vec2 uv, vec2 meshSize, vec2 textureSize) {
vec2 meshRatio = vec2(meshSize.x / meshSize.y, meshSize.y / meshSize.x);
vec2 textureRatio = vec2(textureSize.x / textureSize.y, textureSize.y / textureSize.x);
vec2 resolutionRatio = vec2(
min(meshRatio.x / textureRatio.x, 1.0),
min(meshRatio.y / textureRatio.y, 1.0)
);
return (uv - 0.5) * resolutionRatio + 0.5;
}The colour picture now fills the display screen as proven under.
Yow will discover the code up so far in 01-display-color-image.glsl.
As soon as the colour picture is seen, exchange the ultimate line with the next code and make sure that the grayscale picture is displayed as nicely.
gl_FragColor = outsideColor;
Yow will discover the code up so far in 02-display-grayscale-image.glsl.
The colour and grayscale picture values are named insideColor and outsideColor, respectively, to make their roles within the last end result simpler to grasp.
Constructing a Coordinate System for the Sq.
Subsequent, we create a masks that switches between the grayscale and shade photos. To make the sq.’s middle and dimension simpler to work with, we convert v_uv to the -1.0 to 1.0 vary and create a coordinate system with its origin on the middle of the display screen.
vec2 uvSquare = v_uv * 2.0 - 1.0;Creating the Sq. Masks
We use the uvSquare coordinates created above to construct the masks. Treating u_squareSize as half the size of 1 facet of the sq., we outline its left, proper, backside, and high boundaries.
uniform float u_squareSize;
float squareHalfSize = u_squareSize;
float left = -squareHalfSize;
float proper = squareHalfSize;
float backside = -squareHalfSize;
float high = squareHalfSize;We use step to check whether or not the present pixel lies inside every of the 4 boundaries, then multiply the 4 outcomes collectively. This produces 1.0 contained in the sq., the place each situation is glad, and 0.0 in every single place else.
float squareMask =
step(left, uvSquare.x)
* (1.0 - step(proper, uvSquare.x))
* step(backside, uvSquare.y)
* (1.0 - step(high, uvSquare.y));To verify the form of the masks, we output the squareMask worth instantly as a shade.
gl_FragColor = vec4(vec3(squareMask), 1.0);The within of the masks seems white and the skin black, producing a white rectangle within the middle.
Yow will discover the code up so far in 03-create-square-mask.glsl.
Correcting the Facet Ratio
We now have an oblong masks, however its facet ratio adjustments when the viewport is resized. To appropriate this, we use the mesh dimensions to calculate an aspect-ratio correction issue for figuring out the sq.’s bounds.。
vec2 squareAspectScale = vec2(
min(u_meshSize.y / u_meshSize.x, 1.0),
min(u_meshSize.x / u_meshSize.y, 1.0)
);We divide the coordinates used for the sq. take a look at by this aspect-ratio correction issue, adjusting the masks’s seen space in order that the sq. doesn’t stretch horizontally or vertically.
uvSquare /= squareAspectScale;
Yow will discover the code up so far in 04-correct-mask-aspect-ratio.glsl.
Compositing the Two Photographs
We use the squareMask worth to mix the grayscale and shade photos. The place the masks is 0.0, outsideColor is chosen; the place it’s 1.0, insideColor is chosen. The result’s a sq. crop of the colour picture displayed over the grayscale picture.
vec4 finalColor = combine(outsideColor, insideColor, squareMask);
gl_FragColor = finalColor;
Yow will discover the code up so far in 05-composite-images.glsl.
Making use of the CC Lens Distortion
Subsequent, we apply a CC Lens-style distortion to the colour picture contained in the sq.. First, we convert uvSquare to the 0.0 to 1.0 vary to create native UV coordinates known as squareUv. These coordinates allow us to calculate the lens distortion relative to the sq.’s middle, even when the sq.’s dimension adjustments.
vec2 squareUv = uvSquare / (squareHalfSize * 2.0) + 0.5;We then move these UV coordinates to the getCCLensUv perform to supply UV coordinates distorted by the CC Lens impact. The perform is outlined as follows:
uniform float u_lensDistortion;
float getCCLensScale(float distortion, float radius2) {
if (distortion >= 0.0) {
return 1.0 + distortion * radius2;
}
return 1.0 / (1.0 - distortion * radius2);
}
vec2 getCCLensUv(vec2 uv, vec2 decision, float distortion) {
vec2 centeredUv = uv - 0.5;
vec2 aspectScale = vec2(decision.x / decision.y, 1.0);
vec2 centeredPosition = centeredUv * aspectScale;
float radius2 = dot(centeredPosition, centeredPosition);
float lensScale = getCCLensScale(distortion, radius2);
vec2 distortedPosition = centeredPosition * lensScale;
vec2 distortedCenteredUv = distortedPosition / aspectScale;
vec2 distortedUv = distortedCenteredUv + 0.5;
vec2 distortionOffset = distortedUv - uv;
return uv - distortionOffset;
}The perform first makes use of uv - 0.5 to maneuver the middle of the UV coordinates to the origin, then makes use of dot to calculate the squared distance from that middle. Based mostly on this distance, it calculates a scale that adjustments extra for pixels farther from the middle and offsets the feel sampling place. As a result of we’re making use of the perform to native UV coordinates inside a sq., we move vec2(1.0) as decision to signify a 1:1 facet ratio. For distortion, we move the u_lensDistortion uniform in order that its worth can later be modified by means of the GUI.
vec2 distortedSquareUv = getCCLensUv(squareUv, vec2(1.0), u_lensDistortion);We now have distortedSquareUv, the distorted native UV coordinates contained in the sq.. Nonetheless, utilizing them instantly as the colour picture’s UV coordinates would remap your entire picture into the sq.. We wish the grayscale and shade photos to stay aligned in dimension and place whereas distorting solely the colour picture, so we calculate an offset from the distinction between the UV coordinates earlier than and after distortion. squareLensOffset shops how far the CC Lens impact moved the native UV coordinates inside the sq..
vec2 squareLensOffset = distortedSquareUv - squareUv;Including this offset on to the full-screen v_uv would deal with a square-relative motion as if it had been relative to your entire display screen, making the distortion too massive. We subsequently multiply it by the sq. dimension and the aspect-ratio correction issue, changing the square-relative offset into viewportLensOffset, an offset relative to the full-screen UV coordinates.
vec2 viewportLensOffset = squareLensOffset * squareHalfSize * squareAspectScale;We add the transformed viewportLensOffset to v_uv to create the UV coordinates used to pattern the colour picture.
vec2 lensTexture1Uv = getCoverUv(v_uv + viewportLensOffset, u_meshSize, u_textureSize1);We then exchange the texture1Uv beforehand used to pattern insideColor with lensTexture1Uv.
vec4 insideColor = texture2D(u_texture1, lensTexture1Uv);The colour picture now seems with lens distortion contained in the sq. masks.
Yow will discover the code up so far in 06-apply-cc-lens-distortion.glsl.
Including a Radial RGB Shift
Along with the lens distortion, we apply an RGB shift contained in the sq.. Merely including a continuing worth to the UV coordinates would shift the colours in the identical course and by the identical quantity in every single place within the sq.. As an alternative, as with the lens impact, we use the middle of the sq. because the reference level in order that there isn’t any shade shift on the middle and the shift turns into stronger towards the skin.
The squareUv coordinates used for the lens distortion are native UV coordinates the place the bottom-left nook of the sq. is 0.0 and the top-right nook is 1.0. For the RGB shift, we want the course and distance from the sq.’s middle to every pixel. We first subtract 0.5 from squareUv to maneuver the sq.’s middle to the origin, then multiply by 2.0 to create rgbShiftDirection in a size-independent -1.0 to 1.0 vary.
vec2 rgbShiftDirection = (squareUv - 0.5) * 2.0;The shift quantity for every RGB channel is provided by means of three uniforms: u_rgbShiftR, u_rgbShiftG, and u_rgbShiftB. These values may also be adjustable by means of the GUI. Every element of rgbShiftDirection is 0.0 on the middle of the sq. and reaches -1.0 or 1.0 on the corresponding edge, so every uniform units the utmost per-axis UV shift at that edge. Optimistic and adverse values shift in reverse instructions, whereas 0.0 leaves that channel unchanged.
uniform float u_rgbShiftR;
uniform float u_rgbShiftG;
uniform float u_rgbShiftB;Subsequent, ranging from the lens-distorted lensTexture1Uv, we add an offset for every channel by multiplying rgbShiftDirection by its shift quantity. We then recombine the sampled R, G, and B values into insideColor.
float r = texture2D(u_texture1, lensTexture1Uv + rgbShiftDirection * u_rgbShiftR).r;
float g = texture2D(u_texture1, lensTexture1Uv + rgbShiftDirection * u_rgbShiftG).g;
float b = texture2D(u_texture1, lensTexture1Uv + rgbShiftDirection * u_rgbShiftB).b;
vec4 insideColor = vec4(r, g, b, 1.0);The RGB shift is now utilized. With the default values of 0.01 for R, 0.0 for G, and -0.01 for B, all three channels overlap on the middle of the sq., whereas R and B separate in reverse instructions towards the sides. Later, once we subtract u_mouse from uvSquare to maneuver the sq., the origin of the RGB shift derived from squareUv strikes along with the middle of the lens.
Yow will discover the code up so far in 07-apply-rgb-shift.glsl.
Making the Sq. Observe the Mouse
Subsequent, we make the sq. masks and the middle of the lens observe the mouse. Add a u_mouse uniform and the next line:
uniform vec2 u_mouse;
uvSquare -= u_mouse;DOM mouse coordinates are measured in pixels from the top-left nook, whereas uvSquare makes use of coordinates within the -1.0 to 1.0 vary with the origin on the middle of the display screen. We subsequently convert the mouse coordinates to the identical vary in TypeScript.
public onPointerMove(occasion: PointerEvent): void {
this.mouse.set(
(occasion.clientX / this.windowWidth) * 2 - 1,
-(occasion.clientY / this.windowHeight) * 2 + 1
)
}The Y coordinate is negated as a result of DOM coordinates improve downward, whereas the shader treats upward because the optimistic course.
Then, contained in the render methodology, we use Vector2.lerp for linear interpolation and duplicate the ensuing this.mouseEase worth to u_mouse, making the impact observe the mouse easily.
this.mouseEase.lerp(this.mouse, this.pointerEase)
this.uniforms.u_mouse.worth.copy(this.mouseEase)The sq. masks and lens middle now use the mouse place as their origin and observe its motion easily.
Yow will discover the code up so far in 08-follow-mouse.glsl.
Including Movement to the Outdoors Picture
Subsequent, we add some refined movement solely to the grayscale picture masking the display screen. As a result of each the wave distortion and random distortion we’re about to create animate over time, we first add a u_time uniform.
uniform float u_time;On the TypeScript facet, we convert the elapsed time returned by efficiency.now() to seconds and move it to u_time on each body.
this.uniforms.u_time.worth = efficiency.now() * 0.001Including the Wave Distortion
We use sin so as to add a wave-like impact. The three values u_waveFrequency, u_waveSpeed, and u_waveStrength are added as uniforms to allow them to be adjusted by means of the GUI.
uniform float u_waveFrequency;
uniform float u_waveSpeed;
uniform float u_waveStrength;Utilizing these uniforms, we apply a wave-like offset to the grayscale picture’s sampling place alongside the Y axis.
float wave = sin(texture2Uv.y * u_waveFrequency + u_time * u_waveSpeed) * u_waveStrength;
texture2Uv.y += wave;Including the Random Distortion
Subsequent, we use the random3 perform so as to add fantastic, noise-like distortion. As with the wave, u_randomFrequency, u_randomSpeed, and u_randomStrength are added as uniforms to allow them to be adjusted by means of the GUI.
uniform float u_randomFrequency;
uniform float u_randomSpeed;
uniform float u_randomStrength;The random3 perform is customized from this Shadertoy instance.Somewhat than penning this perform instantly within the fragment shader, we transfer it into glsl/chunks/random3.glsl in order that it may be reused by different shaders.
//
// by Nikita Miropolskiy
vec3 random3(vec3 c) {
float j = 4096.0 * sin(dot(c, vec3(17.0, 59.4, 15.0)));
vec3 r;
r.z = fract(512.0 * j);
j *= 0.125;
r.x = fract(512.0 * j);
j *= 0.125;
r.y = fract(512.0 * j);
return r - 0.5;
} Earlier than the most important perform in frag.glsl, we embody this chunk in the identical approach as coverUv.glsl and ccLens.glsl. Through the construct, the perform physique is inserted on the #embody directive, permitting most important to name it like a daily GLSL perform.
#embody "../chunks/random3.glsl"Inside most important, we use the random3 perform to offset texture2Uv as follows:
texture2Uv += random3(vec3(texture2Uv * u_randomFrequency, u_time * u_randomSpeed)).x * u_randomStrength;This completes the impact proven at first!
Including GUI Controls
The visible impact and interplay are actually full. Lastly, we add the parameters to a GUI in order that we will alter the sq. dimension, lens energy, RGB shift quantities, wave and random movement, and extra.
Defining the Shader Parameters
The Webgl class manages the logic that ties the demo collectively, together with initialization of the Stage and Mesh courses, occasion registration, and the render loop. Since it is a standard construction, we are going to skip the small print and give attention to creating the GUI and updating the shader parameters. The default parameter values are managed within the Webgl class’s constructor.
this.shaderParams = {
squareSize: 0.3,
lensDistortion: 1.5,
rgbShiftR: 0.01,
rgbShiftG: 0,
rgbShiftB: -0.01,
waveFrequency: 10,
waveStrength: 0.01,
waveSpeed: 1,
randomFrequency: 1,
randomStrength: 0.02,
randomSpeed: 0.2,
pointerEase: 0.1
}Creating the GUI
The GUI is created and its parameters are added within the Webgl class’s setGUI methodology. Right here, we add the parameters to folders organized by impact.
non-public setGUI(): void {
this.destroyGUI()
this.gui = new GUI({
title: "Sq. Texture Impact"
})
this.gui.onChange(this.updateShaderParams)
const squareFolder = this.gui.addFolder("Sq.")
const rgbShiftFolder = this.gui.addFolder("RGB Shift")
const waveFolder = this.gui.addFolder("Wave")
const randomFolder = this.gui.addFolder("Random")
const pointerFolder = this.gui.addFolder("Pointer")
squareFolder
.add(this.shaderParams, "squareSize", 0, 5, 0.01)
.title("Sq. Measurement")
squareFolder
.add(this.shaderParams, "lensDistortion", -5, 5, 0.01)
.title("Lens Distortion")
rgbShiftFolder
.add(this.shaderParams, "rgbShiftR", -0.05, 0.05, 0.001)
.title("Crimson Shift")
rgbShiftFolder
.add(this.shaderParams, "rgbShiftG", -0.05, 0.05, 0.001)
.title("Inexperienced Shift")
rgbShiftFolder
.add(this.shaderParams, "rgbShiftB", -0.05, 0.05, 0.001)
.title("Blue Shift")
waveFolder
.add(this.shaderParams, "waveFrequency", 0, 200, 1)
.title("Wave Frequency")
waveFolder
.add(this.shaderParams, "waveStrength", 0, 0.1, 0.001)
.title("Wave Power")
waveFolder
.add(this.shaderParams, "waveSpeed", 0, 5, 0.01)
.title("Wave Velocity")
randomFolder
.add(this.shaderParams, "randomFrequency", 0.1, 20, 0.1)
.title("Random Frequency")
randomFolder
.add(this.shaderParams, "randomStrength", 0, 0.1, 0.001)
.title("Random Power")
randomFolder
.add(this.shaderParams, "randomSpeed", 0, 2, 0.01)
.title("Random Velocity")
pointerFolder
.add(this.shaderParams, "pointerEase", 0.01, 1, 0.01)
.title("Pointer Ease")
}Updating the Uniforms
When a parameter adjustments within the GUI, shaderParams is handed to the Mesh class by means of the updateShaderParams methodology.
non-public updateShaderParams = (): void => {
if (this.mesh) {
this.mesh.setShaderParams(this.shaderParams)
}
}Within the Mesh class, the values acquired from the GUI are assigned to their corresponding uniforms as proven under. As a result of pointerEase is just not handed to the shader, it’s up to date as a property of the Mesh class as a substitute. This lets us change the parameter values in actual time.
public setShaderParams({
squareSize,
lensDistortion,
rgbShiftR,
rgbShiftG,
rgbShiftB,
waveFrequency,
waveStrength,
waveSpeed,
randomFrequency,
randomStrength,
randomSpeed,
pointerEase
}: ShaderParams): void {
this.uniforms.u_squareSize.worth = squareSize
this.uniforms.u_lensDistortion.worth = lensDistortion
this.uniforms.u_rgbShiftR.worth = rgbShiftR
this.uniforms.u_rgbShiftG.worth = rgbShiftG
this.uniforms.u_rgbShiftB.worth = rgbShiftB
this.uniforms.u_waveFrequency.worth = waveFrequency
this.uniforms.u_waveStrength.worth = waveStrength
this.uniforms.u_waveSpeed.worth = waveSpeed
this.uniforms.u_randomFrequency.worth = randomFrequency
this.uniforms.u_randomStrength.worth = randomStrength
this.uniforms.u_randomSpeed.worth = randomSpeed
this.pointerEase = pointerEase
}The GUI is now full as nicely. Strive adjusting the values to see how they alter the looks of the impact!
Conclusion
What did you assume? I hope this text confirmed that even an impact that appears advanced at first look might be constructed by combining small, easy components. You may additionally add your personal parameters to this implementation or change the adjustable ranges to create one thing unique. This undertaking was impressed by a single picture I discovered on Pinterest, however concepts are in every single place: in photos, web sites, movies, and on a regular basis life. When one thing catches your consideration, attempt turning it into code as we did right here. Lastly, when you’ve got any questions on this text, be happy to contact me on X. Thanks for studying!
