rasterizeTriangle()Rasterize the triangle defined by vertices (row0, col0), (row1, col1), and (row2, col2), using barycentric coordinates. The user provided software rendered (fragment) shader is a function parameterized with the object literal { pattern: interpolated_data_array, row: i, col: j } and that should return a p5.Color. Refer to the colorizeTriangle() method for an example.
rasterizeTriangle(row0, col0, row1, col1, row2, col2, shader, pattern0, [pattern1], [pattern2])
| row0 | Number: vertex0 row coordinate |
| col0 | Number: vertex0 col coordinate |
| row1 | Number: vertex1 row coordinate |
| col1 | Number: vertex1 col coordinate |
| row2 | Number: vertex2 row coordinate |
| col2 | Number: vertex2 col coordinate |
| shader | Function: taking { pattern: interpolated_data_array, row: i, col: j } params and returning a p5.Color |
| pattern0 | Array: vertex0 attributes to be interpolated |
| pattern1 | Array: vertex1 attributes to be interpolated default is pattern0 |
| pattern2 | Array: vertex2 attributes to be interpolated default is pattern0 |
