Ok It worked … I tried drawing a Polygon instead of Text in 2D, while movin my Cam in 3D…
My problem was this:
glClear();
gluLookAt( cam values );
glPushMatrix();
drawStuff();
collision=determineCollision();
glPopMatrix();
glMatrixMode(GL_PROJECTION);
glPushMatrix();
glLoadIdentity();
glOrtho();
glMatrixMode(GL_MODELVIEW)
draw2DstuffHERE();
glMatrixMode(GL_PROJECTION);
glPopMatrix();
glMatrixMode(GL_MODELVIEW);
glFlush();
