specifying per-vertex color for filling quads
Jun 3rd, 2009, 11:32am  
is it possible to give each vertex of a quad its own color and have the fill color of the quad be the gradient between the colors of the vertices?

ive done it with regular c++/opengl but it seems like processing in its natural form has no equivalent to glColor3f. do i have to do it the "hard" opengl way?

im trying to make a new version of this sketch, http://openprocessing.org/visuals/?visualID=2199, but im only able to get single fill colors so far and it would be a lot more organic looking with per-vertex color.

Change the fill() color before each vertex of a QUADS shape.

This post has a good example:
