Could anyone tell how to set the camera/viewport to orthographic mode? (and especially how I update the creen after the modification, which I don’t know how to do)

check the faq (link first page)

Hi

Use for example:
.
.
.
glViewport(0,0,(GLsizei)screenwidth,(GLsizei)screenheight);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(0, screenwidth, 0, screenheight);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
.
.
.

You don’t need to set a camera.

<blinks> gluOrtho2D is setting the camera, and you DO need to define an orthographic camera for orthographic projection.
