rasterize()Rasterize quadrille according to upper-left corner vertex pattern0, bottom-left corner vertex pattern1, upper-right corner vertex pattern2, and bottom-right corner vertex pattern3, using (fragment) shader. Call rasterizeTriangle() on the two non-overlapping triangles entirely covering the quadrille.
rasterize(shader, pattern0, [pattern1], [pattern2], [pattern3])
| shader | Function: taking { pattern: interpolated_data_array, row: i, col: j } params and returning a p5.Color |
| pattern0 | Array: corner0 attributes to be interpolated |
| pattern1 | Array: corner1 attributes to be interpolated default is pattern0 |
| pattern2 | Array: corner2 attributes to be interpolated default is pattern0 |
| pattern3 | Array: corner3 attributes to be interpolated default is pattern0 |
