WebGL pipeline
by Lea Rosema
Description
anchor- An array of vertices (or any data) is uploaded into a buffer which is split into data records
- the vertex shader is executed once per data record
- for each data record, the vertex shader program gets the data value into an attribute variable and writes it into an output position variable
- the made up shape gets rasterized into fragments (pixels)
- the fragment shader calculates the color for each pixel
