Advanced WebGL Techniques

Advanced Topics in WebGL

In this tutorial, we'll cover advanced topics in WebGL, including lighting, textures, and animations.

Lighting

Learn how to implement lighting in your WebGL scenes.

Textures

Learn how to use textures in your WebGL scenes.

 // Load a texture
 const texture = gl.createTexture();
 gl.bindTexture(gl.TEXTURE_2D, texture);
 gl.texImage2D(gl.TEXTURE_2D, 0, gl.RGBA, gl.RGBA, gl.UNSIGNED_BYTE, image);
 

Animations

Learn how to create animations in your WebGL scenes.

 // Animate a rotating cube
 function animate() {
 gl.clear(gl.COLOR_BUFFER_BIT | gl.DEPTH_BUFFER_BIT);

 // Rotate the cube
 const modelViewMatrix = [
 Math.cos(angle), -Math.sin(angle), 0, 0,
 Math.sin(angle), Math.cos(angle), 0, 0,
 0, 0, 1, 0,
 0, 0, -5, 1,
 ];

 const modelViewProjectionMatrix = multiplyMatrices(projectionMatrix, modelViewMatrix);
 gl.uniformMatrix4fv(modelViewProjectionLocation, false, modelViewProjectionMatrix);

 gl.drawElements(gl.TRIANGLES, 36, gl.UNSIGNED_SHORT, 0);

 angle += 0.01;
 requestAnimationFrame(animate);
 }
