Triangle look weird when part of it is off screen?
Author
Hi! I''m having quite a problem.
When i render a triangle with one of it''s vertexes off the screen, the color on that vertex become random. (!)
Is there a bug, or did i miss something?
glBegin(GL_TRIANGLES);
glColor3f(1.0f,1.0f,1.0f);
glVertex3f(0.0f,0.0f,0.0f);
glVertex3f(40.0f,0.0f,0.0f);
glVertex3f(0.0f,3.0f,0.0f);
glEnd();

May sounds stupid but... How can you actually see the color on that vertex is weird if it''s OFF screen ?

You see the weird colour interpolated over the triangle...
Electron: Do you have a Voodoo2 ? Or a Voodoo3 under WinNT ? The effect you described is a known bug of V2 drivers (all OS''s) and V3 drivers (NT only). It''s in the 2D clipping code.
If you have another gfx card, then forget about that...
But it might still be a driver issue. Try with the M$ software driver, if it works, then it''s a driver problem.
