OPENGL/SERIAL on 3 screens = problems...
Jun 24th, 2007, 1:07pm  
Hey
I am making a project with 3 screens conected to 1 computer with 3 graphiccards. In the 2 first screens there is 2 different pictures displayed and in the last screen there is a blend of the 2 pictures. The screens are 1680*1050, so the pictures are pretty large.

I am using an ardoinoboard to change the pictures, but because of the big pictures and the 3 screens the change is very slow. Then i have tryed using OpenGL to solw this problem, but is not working, and have created 2 new problems.

1: By using OpenGL the displayed is blinking! Why?

2: Is it wright that the "blend" command dosn't work with OpenGl? And what to do then?

I really hope somebody has some answers!

Johanne

blend() is broken in opengl:

what to do is either wait for a fix or help me fix it.

i don't know about the blinking, though it may have to do with the blend() issues, or you'd need to show some code.
