Hi all, Anyone has a nice link to suggest me to understand well how we can imitate the blending mode that we find in popular graphics programs (such as Photoshop) like "burn", "add", "overlay" and such, using different arguments to the OpenGL function glBlenFunc() ? It's pretty well explained in the red book : http://www.glprogramming.com/red/chapter06.html but I would like something more straightforward. For instance, how can we imitate the pretty complex "overlay" mode ?
Thanks,
