How can I use typed arrays with WebGL?

You can use typed arrays in WebGL to efficiently manage and manipulate vertex data. They allow you to store data in a format that WebGL can process quickly.

What types of typed arrays are best for WebGL?

The most commonly used typed arrays in WebGL are Float32Array for vertex positions and Uint16Array for element indices.

Can you show me a code example?

Sure! Here's a simple example:

const vertices = new Float32Array([
  -0.5, -0.5, 0.0,
   0.5, -0.5, 0.0,
   0.0,  0.5, 0.0
]);

const buffer = gl.createBuffer();
gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
gl.bufferData(gl.ARRAY_BUFFER, vertices, gl.STATIC_DRAW);

What are the performance benefits of using typed arrays?

Typed arrays provide better performance because they allow WebGL to access data in a more efficient binary format, reducing overhead and improving rendering speed.
