WebGL Buffers: Telling the GPU How to Read Your Data
WebGL's vertexAttribPointer is the map you give the GPU to read vertex data from a buffer. It tells your shader how to parse a flat byte array into attributes like position. This is how you link CPU data to the GPU before drawing.
`vertexAttribPointer` is the critical link between raw vertex data in a WebGL buffer and the shader attributes that use it. It's an instruction manual for the GPU, explaining how to parse a flat byte array into meaningful data like vertex positions or colors. You call it after binding a buffer to `gl.ARRAY_BUFFER` to configure how the GPU steps through that data for a shader attribute before drawing.
