The textured cubeThe changes to the drawScene() function are simple. Note: In the drawScene() function of your "draw-scene.js" module, add the following function: function setTextureAttribute(gl, buffers, programInfo) { const num = 2; const type = gl.FLOAT; const normalize = false; const stride = 0; const offset = 0; gl.bindBuffer(gl.ARRAY_BUFFER, buffers.textureCoord); gl.vertexAttribPointer( programInfo.attribLocations.textureCoord, num, type, normalize, stride, offset, ); gl.enableVertexAttribArray(programInfo.attribLocations.textureCoord);} Note: In the drawScene() function of your "draw-scene.js" module, replace the call to setColorAttribute() with the following line: setTextureAttribute(gl, buffers, programInfo); Then add code to specify the texture to map onto the faces. Note: In your drawScene() function, just after the two calls to gl.uniformMatrix4fv(), add the following code: gl.activeTexture(gl.TEXTURE0);gl.bindTexture(gl.TEXTURE_2D, texture);gl.uniform1i(programInfo.uniformLocations.uSampler, 0); WebGL provides a minimum of 8 texture units; the first of these is gl.TEXTURE0. We tell WebGL we want to affect unit 0. We then call bindTexture() which binds the texture to the TEXTURE_2D bind point of texture unit 0. We then tell the shader that for the uSampler use texture unit 0. Lastly, add texture as a parameter to the drawScene() function, both where it is defined and where it is called. Note: Update the declaration of your drawScene() function to add the new parameter: function drawScene(gl, programInfo, buffers, texture, cubeRotation) { Note: Update the place in your main() function where you call drawScene(): drawScene(gl, programInfo, buffers, texture, cubeRotation); At this point, the rotating cube should be good to go.

You can set the renderOnUpdate prop on the Canvas component to true to have it work something like a regular react component tree. If the scene has lots of elements or is animating constantly it's going to make more sense to render it in more controlled way with the useRender hook.Rendering in a loopYou can get a function to render the scene by calling useRender anywhere in a React Vertex component tree. If your scene is animating constantly, it's probably best to have one loop right at the root of the tree that renders on each frame. You can use d3-timer to create a loop like so:import React, { useEffect } from 'react'import { timer } from 'd3-timer'import { useRender } from '@react-vertex/core'function Scene() { const renderScene = useRender() useEffect(() => { const timerLoop = timer(renderScene) return () => timerLoop.stop() },
