read those articles already you might want to read them first. + +In a [previous article](webgpu-textures.html) we covered how to use textures, +how they are referenced by texture coordinates that go from 0 to 1 across and up +the texture, and how they are filtered optionally using mips. + +Another kind of texture is a *cubemap*. A cubemap consists of 6 faces representing +the 6 faces of a cube. Instead of the traditional texture coordinates that +have 2 dimensions, a cubemap uses a normal or in other words a 3D direction. +Depending on the direction the normal points one of the 6 faces of the cube +is selected and then within that face the pixels are sampled to produce a color. + +Let's make a simple example, we'll use a 2D canvas to make the images used in +each of the 6 faces. + +Here's some code to fill a canvas with a color and a centered message + +```js +function generateFace(size, {faceColor, textColor, text}) { + const canvas = document.createElement('canvas'); + canvas.width = size; + canvas.height = size; + const ctx = canvas.getContext('2d'); + ctx.fillStyle = faceColor; + ctx.fillRect(0, 0, size, size); + ctx.font = `${size * 0.7}px sans-serif`; + ctx.textAlign = 'center'; + ctx.textBaseline = 'middle'; + ctx.fillStyle = textColor; + ctx.fillText(text, size / 2, size / 2); + return canvas; +} +``` + +And here's some code to call it to generate 6 images + +```js +const faceSize = 128; +const faceCanvases = [ + { faceColor: '#F00', textColor: '#0FF', text: '+X' }, + { faceColor: '#FF0', textColor: '#00F', text: '-X' }, + { faceColor: '#0F0', textColor: '#F0F', text: '+Y' }, + { faceColor: '#0FF', textColor: '#F00', text: '-Y' }, + { faceColor: '#00F', textColor: '#FF0', text: '+Z' }, + { faceColor: '#F0F', textColor: '#0F0', text: '-Z' }, +].map(faceInfo => generateFace(faceSize, faceInfo)); + +// show the results +for (const canvas of faceCanvases) { + document.body.appendChild(canvas); +} +``` + +{{{example url="../webgpu-cube-faces.html" }}} + +Now let's apply those to a cube using a cubemap.

This seems like a good bet +because it would be very rare for them to be different sizes for layers of the same texture. + +Now we need to update `copySourceToTexture` to handle multiple sources. + +```js +- function copySourceToTexture(device, texture, source, {flipY} = {}) { ++ function copySourcesToTexture(device, texture, sources, {flipY} = {}) { ++ sources.forEach((source, layer) => { +* device.queue.copyExternalImageToTexture( +* { source, flipY, }, +- { texture }, ++ { texture, origin: [0, 0, layer] }, +* { width: source.width, height: source.height }, +* ); ++ }); + + if (texture.mipLevelCount > 1) { + generateMips(device, texture); + } + } +``` + +Above, the only major difference is we added a loop to loop over the sources +and we set an `origin` for where in the texture to copy the source so that +we copy each source to its respective layer. + +Now we need to update `generateMips` to handle multiple sources. + +```js + const generateMips = (() => { + let sampler; + let module; + const pipelineByFormat = {}; + + return function generateMips(device, texture) { + if (!module) { + module = device.createShaderModule({ + label: 'textured quad shaders for mip level generation', + code: ` + struct VSOutput { + @builtin(position) position: vec4f, + @location(0) texcoord: vec2f, + }; + + @vertex fn vs( + @builtin(vertex_index) vertexIndex : u32 + ) -> VSOutput { + let pos = array( + + vec2f( 0.0, 0.0), // center + vec2f( 1.0, 0.0), // right, center + vec2f( 0.0, 1.0), // center, top + + // 2st triangle + vec2f( 0.0, 1.0), // center, top + vec2f( 1.0, 0.0), // right, center + vec2f( 1.0, 1.0), // right, top + ); + + var vsOutput: VSOutput; + let xy = pos[vertexIndex]; + vsOutput.position = vec4f(xy * 2.0 - 1.0, 0.0, 1.0); + vsOutput.texcoord = vec2f(xy.x, 1.0 - xy.y); + return vsOutput; + } + + @group(0) @binding(0) var ourSampler: sampler; + @group(0) @binding(1) var ourTexture: texture_2d; + + @fragment fn fs(fsInput: VSOutput) -> @location(0) vec4f { + return textureSample(ourTexture, ourSampler, fsInput.texcoord); + } + `, + }); + + sampler = device.createSampler({ + minFilter: 'linear', + magFilter: 'linear', + }); + } + + if (!pipelineByFormat[texture.format]) { + pipelineByFormat[texture.format] = device.createRenderPipeline({ + label: 'mip level generator pipeline', + layout: 'auto', + vertex: { + module, + entryPoint: 'vs', + }, + fragment: { + module, + entryPoint: 'fs', + targets: [{ format: texture.format }], + }, + }); + } + const pipeline = pipelineByFormat[texture.format]; + + const encoder = device.createCommandEncoder({ + label: 'mip gen encoder', + }); + + let width = texture.width; + let height = texture.height; + let baseMipLevel = 0; + while (width > 1 || height > 1) { + width = Math.max(1, width / 2 | 0); + height = Math.max(1, height / 2 | 0); + ++ for (let layer = 0; layer < texture.depthOrArrayLayers; ++layer) { +* const bindGroup = device.createBindGroup({ +* layout: pipeline.getBindGroupLayout(0), +* entries: [ +* { binding: 0, resource: sampler }, +- { binding: 1, resource: texture.createView({baseMipLevel, mipLevelCount: 1}) }, ++ { ++ binding: 1, ++ resource: texture.createView({ ++ dimension: '2d', ++ baseMipLevel, ++ mipLevelCount: 1, ++ baseArrayLayer: layer, ++ arrayLayerCount: 1, ++ }), +* }, +* ], +* }); +* +- ++baseMipLevel; +* +* const renderPassDescriptor = { +* label: 'our basic canvas renderPass', +* colorAttachments: [ +* { +- view: texture.createView({baseMipLevel, mipLevelCount: 1}), ++ view: texture.createView({ ++ dimension: '2d', ++ baseMipLevel: baseMipLevel + 1, ++ mipLevelCount: 1, ++ baseArrayLayer: layer, ++ arrayLayerCount: 1, ++ }), +* loadOp: 'clear', +* storeOp: 'store', +* }, +* ], +* }; +* +* const pass = encoder.beginRenderPass(renderPassDescriptor); +* pass.setPipeline(pipeline); +* pass.setBindGroup(0, bindGroup); +* pass.draw(6); // call our vertex shader 6 times +* pass.end(); ++ } ++ ++baseMipLevel; ++ } + + const commandBuffer = encoder.finish(); + device.queue.submit([commandBuffer]); + }; + })(); +``` + +We added a loop to handle each layer of the texture. +We changed the views so they select a single layer.

+ +If we did nothing else you might think we'd have to draw 2 times for +the chair, once for the wood with a wood texture, and once for the +cushion with a cloth texture. For the car we'd have several draws, one for +the tires, one for the body, one for the bumpers, etc... + +That would end up being slow as every object would require multiple +draw calls. We could try to fix that by adding more inputs to our +shader (2, 3, 4 textures) with texture coordinates for each one +but that would not be very flexible and would be slow as well +as we'd need to read all 4 textures and add code to chose between them. + +The most common way to cover this case is to use what's called a +[Texture Atlas](https://www.google.com/search?q=texture+atlas). +A Texture Atlas is a fancy name for a texture with +multiple images it in. We then use texture coordinates to select +which parts go where. + +Let's wrap a cube with these 6 images + +
+ + + + + +
+
+ +Using some image editing software like Photoshop or [Photopea](https://photopea.com) we could put all 6 images into a single image + + + +We'd then make a cube and provide texture coordinates that select each +portion of the image onto a specific face of the cube. To keep it simple I put +all 6 images in the texture above in squares, 4x2. So it should be pretty +easy to compute the texture coordinates for each square. + +
+
+
+
+
+ +> The diagram above might be confusing because it is often suggested that texture coordinates +> have 0,0 as the bottom left corner. Really though there is no "bottom". There is just the idea +> that texture coordinate 0,0 references the first pixel in the texture's data. The first +> pixel in the texture's data is the top left corner of the image. +> If you subscribe to the idea that 0,0 = bottom left then our texture coordinates +> would be visualized like this. **They're still the same coordinates**. + +

0,0 at bottom left
+
+
+ + +Here's the position vertices for a cube and the texture coordinates +to go with them + +```js +function createCubeVertices() { + const vertexData = new Float32Array([ + // position | texture coordinate + //-------------+---------------------- + // front face select the top left image + -1, 1, 1, 0 , 0 , + -1, -1, 1, 0 , 0.5, + 1, 1, 1, 0.25, 0 , + 1, -1, 1, 0.25, 0.5, + // right face select the top middle image + 1, 1, -1, 0.25, 0 , + 1, 1, 1, 0.5 , 0 , + 1, -1, -1, 0.25, 0.5, + 1, -1, 1, 0.5 , 0.5, + // back face select to top right image + 1, 1, -1, 0.5 , 0 , + 1, -1, -1, 0.5 , 0.5, + -1, 1, -1, 0.75, 0 , + -1, -1, -1, 0.75, 0.5, + // left face select the bottom left image + -1, 1, 1, 0 , 0.5, + -1, 1, -1, 0.25, 0.5, + -1, -1, 1, 0 , 1 , + -1, -1, -1, 0.25, 1 , + // bottom face select the bottom middle image + 1, -1, 1, 0.25, 0.5, + -1, -1, 1, 0.5 , 0.5, + 1, -1, -1, 0.25, 1 , + -1, -1, -1, 0.5 , 1 , + // top face select the bottom right image + -1, 1, 1, 0.5 , 0.5, + 1, 1, 1, 0.75, 0.5, + -1, 1, -1, 0.5 , 1 , + 1, 1, -1, 0.75, 1 , + + ]); + + const indexData = new Uint16Array([ + 0, 1, 2, 2, 1, 3, // front + 4, 5, 6, 6, 5, 7, // right + 8, 9, 10, 10, 9, 11, // back + 12, 13, 14, 14, 13, 15, // left + 16, 17, 18, 18, 17, 19, // bottom + 20, 21, 22, 22, 21, 23, // top + ]); + + return { + vertexData, + indexData, + numVertices: indexData.length, + }; +} +``` + +To make this example we're going to have start with an example from [the article on cameras](webgpu-cameras.html). +If you haven't read the article yet you can read it and the series it's a part of the learn how do 3D. +For now, the important part is, like we did above, we output positions and texture coordinates from our +vertex shader and use them to look up values from a texture in our fragment shader. So, here's +the changes needed from the shader in the camera example, applying what we have above. + +```wgsl +struct Uniforms { + matrix: mat4x4f, +}; + +struct Vertex { + @location(0) position: vec4f, +- @location(1) color: vec4f, ++ @location(1) texcoord: vec2f, +}; + +struct VSOutput { + @builtin(position) position: vec4f, +- @location(0) color: vec4f, ++ @location(0) texcoord: vec2f, +}; + +@group(0) @binding(0) var uni: Uniforms; ++@group(0) @binding(1) var ourSampler: sampler; ++@group(0) @binding(2) var ourTexture: texture_2d; + +@vertex fn vs(vert: Vertex) -> VSOutput { + var vsOut: VSOutput; + vsOut.position = uni.matrix * vert.position; +- vsOut.color = vert.color; ++ vsOut.texcoord = vert.texcoord; + return vsOut; +} + +@fragment fn fs(vsOut: VSOutput) -> @location(0) vec4f { +- return vsOut.color; ++ return textureSample(ourTexture, ourSampler, vsOut.texcoord); +} +``` + +All we did was switch from taking a color per vertex to a texture coordinate per vertex +and passing that texture coordinate to the fragment shader, like we did above. We then +use it, in the fragment shader, like we did above. + +In JavaScript we need to change that example's pipeline from taking a color to taking +texture coordinates + +```js + const pipeline = device.createRenderPipeline({ + label: '2 attributes', + layout: 'auto', + vertex: { + module, + entryPoint: 'vs', + buffers: [ + { +- arrayStride: (4) * 4, // (3) floats 4 bytes each + one 4 byte color ++ arrayStride: (3 + 2) * 4, // (3+2) floats 4 bytes each + attributes: [ + {shaderLocation: 0, offset: 0, format: 'float32x3'}, // position +- {shaderLocation: 1, offset: 12, format: 'unorm8x4'}, // color ++ {shaderLocation: 1, offset: 12, format: 'float32x2'}, // texcoord + ], + }, + ], + }, + fragment: { + module, + entryPoint: 'fs', + targets: [{ format: presentationFormat }], + }, + primitive: { + cullMode: 'back', + }, + depthStencil: { + depthWriteEnabled: true, + depthCompare: 'less', + format: 'depth24plus', + }, + }); +``` + +To keep the data smaller we're going to use a indices like we covered in [the article on vertex buffers](webgpu-vertex-buffers.html). + +```js +- const { vertexData, numVertices } = createFVertices(); ++ const { vertexData, indexData, numVertices } = createCubeVertices(); + const vertexBuffer = device.createBuffer({ + label: 'vertex buffer vertices', + size: vertexData.byteLength, + usage: GPUBufferUsage.VERTEX | GPUBufferUsage.COPY_DST, + }); + device.queue.writeBuffer(vertexBuffer, 0, vertexData); + ++ const indexBuffer = device.createBuffer({ ++ label: 'index buffer', ++ size: vertexData.byteLength, ++ usage: GPUBufferUsage.INDEX | GPUBufferUsage.COPY_DST, ++ }); ++ device.queue.writeBuffer(indexBuffer, 0, indexData); +``` + +We need to copy all of the texture loading and mip generation code into this example +and then use it to load the texture atlas image. We also need to make a sampler +and add them our bindGroup + +```js ++ const texture = await createTextureFromImage(device, ++ 'resources/images/noodles.jpg', {mips: true, flipY: false}); ++ ++ const sampler = device.createSampler({ ++ magFilter: 'linear', ++ minFilter: 'linear', ++ mipmapFilter: 'linear', ++ }); + + const bindGroup = device.createBindGroup({ + label: 'bind group for object', + layout: pipeline.getBindGroupLayout(0), + entries: [ + { binding: 0, resource: { buffer: uniformBuffer }}, ++ { binding: 1, resource: sampler }, ++ { binding: 2, resource: texture.createView() }, + ], + }); +``` + +We need to do some 3D math to setup a matrix for drawing in 3D. (Again, see [the camera article](webgpu-cameras.html) for +details on 3D math. + +```js + const degToRad = d => d * Math.PI / 180; + + const settings = { + rotation: [degToRad(20), degToRad(25), degToRad(0)], + }; + + const radToDegOptions = { min: -360, max: 360, step: 1, converters: GUI.converters.radToDeg }; + + const gui = new GUI(); + gui.onChange(render); + gui.add(settings.rotation, '0', radToDegOptions).name('rotation.x'); + gui.add(settings.rotation, '1', radToDegOptions).name('rotation.y'); + gui.add(settings.rotation, '2', radToDegOptions).name('rotation.z'); + + ... + + function render() { + + ... + + const aspect = canvas.clientWidth / canvas.clientHeight; + mat4.perspective( + 60 * Math.PI / 180, + aspect, + 0.1, // zNear + 10, // zFar + matrixValue, + ); + const view = mat4.lookAt( + [0, 1, 5], // camera position + [0, 0, 0], // target + [0, 1, 0], // up + ); + mat4.multiply(matrixValue, view, matrixValue); + mat4.rotateX(matrixValue, settings.rotation[0], matrixValue); + mat4.rotateY(matrixValue, settings.rotation[1], matrixValue); + mat4.rotateZ(matrixValue, settings.rotation[2], matrixValue); + + // upload the uniform values to the uniform buffer + device.queue.writeBuffer(uniformBuffer, 0, uniformValues); +``` + +And at render time we need to draw with indices + +```js + const encoder = device.createCommandEncoder(); + const pass = encoder.beginRenderPass(renderPassDescriptor); + pass.setPipeline(pipeline); + pass.setVertexBuffer(0, vertexBuffer); ++ pass.setIndexBuffer(indexBuffer, 'uint16'); + + ... + + pass.setBindGroup(0, bindGroup); +- pass.draw(numVertices); ++ pass.drawIndexed(numVertices); + + pass.end(); +``` + +And we that we get a cube, with a different image on each side, using a single texture. + +{{{example url="../webgpu-texture-atlas.html"}}} + +Using a texture atlas is good because there's just 1 texture to load, the shader stays simple as it only has to reference 1 texture, and it only +requires 1 draw call to draw the shape instead of 1 draw call per texture as it might if we keep the images separate. + + + + diff --git a/webgpu/lessons/webgpu-typedarrays.md b/webgpu/lessons/webgpu-typedarrays.md deleted file mode 100644 index e1b3d90e..00000000 --- a/webgpu/lessons/webgpu-typedarrays.md +++ /dev/null @@ -1,6 +0,0 @@ -Title: WebGPU TypedArrays -Description: Using TypedArrays -TOC: TypedArrays - -TBD - diff --git a/webgpu/resources/images/noodles.jpg b/webgpu/resources/images/noodles.jpg new file mode 100644 index 00000000..d98dfe8a Binary files /dev/null and b/webgpu/resources/images/noodles.jpg differ diff --git a/webgpu/resources/models/gltf/cc0_chair.glb b/webgpu/resources/models/gltf/cc0_chair.glb new file mode 100644 index 00000000..9ec59807 Binary files /dev/null and b/webgpu/resources/models/gltf/cc0_chair.glb differ diff --git a/webgpu/resources/models/gltf/cco_chair.txt b/webgpu/resources/models/gltf/cco_chair.txt new file mode 100644 index 00000000..27e71b29 --- /dev/null +++ b/webgpu/resources/models/gltf/cco_chair.txt @@ -0,0 +1 @@ +"[CC0] Chair" (https://skfb.ly/opnwY) by adadadad5252341 is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/by/4.0/). diff --git a/webgpu/resources/models/gltf/classic_muscle_car.glb b/webgpu/resources/models/gltf/classic_muscle_car.glb new file mode 100644 index 00000000..b033c564 Binary files /dev/null and b/webgpu/resources/models/gltf/classic_muscle_car.glb differ diff --git a/webgpu/resources/models/gltf/classic_muscle_car.txt b/webgpu/resources/models/gltf/classic_muscle_car.txt new file mode 100644 index 00000000..d250db6f --- /dev/null +++ b/webgpu/resources/models/gltf/classic_muscle_car.txt @@ -0,0 +1 @@ +"Classic Muscle car" (https://skfb.ly/6Usqo) by Lexyc16 is licensed under Creative Commons Attribution (http://creativecommons.org/licenses/by/4.0/). diff --git a/webgpu/webgpu-cube-faces.html b/webgpu/webgpu-cube-faces.html new file mode 100644 index 00000000..f263de2f --- /dev/null +++ b/webgpu/webgpu-cube-faces.html @@ -0,0 +1,45 @@ + + + + WebGPU Textured Cube Map + + + + + + diff --git a/webgpu/webgpu-cube-map.html b/webgpu/webgpu-cube-map.html new file mode 100644 index 00000000..6e023c96 --- /dev/null +++ b/webgpu/webgpu-cube-map.html @@ -0,0 +1,501 @@ + + + + WebGPU Textured Cube Map + + + + + + + diff --git a/webgpu/webgpu-cube-mutiple.html b/webgpu/webgpu-cube-mutiple.html deleted file mode 100644 index 28a0991f..00000000 --- a/webgpu/webgpu-cube-mutiple.html +++ /dev/null @@ -1,344 +0,0 @@ - - - - WebGPU Cube Multiple - - - - - - - - \ No newline at end of file diff --git a/webgpu/webgpu-texture-atlas.html b/webgpu/webgpu-texture-atlas.html new file mode 100644 index 00000000..f9cbec6d --- /dev/null +++ b/webgpu/webgpu-texture-atlas.html @@ -0,0 +1,839 @@ + + + + WebGPU Perspective - Matrix Z to W - Step 3 + + + + +
