glortho problems

[dcTom]

Hello, i had this Problem already a view years ago, but coult not fix it until now..

when im using glortho, the depth check doesnt work.

Code: Select all

        glMatrixMode(GL_PROJECTION);
	glLoadIdentity();
	glOrtho(0, 640, 0, 480, -10, 10);
	glMatrixMode(GL_MODELVIEW);
	glEnable(GL_DEPTH_TEST);
	glDepthFunk(GL_LESS);
	glLoadIdentity();

I set 3 rectangle + texture and one background as long is rectangle are 64x64 or 32x32 .. they are displayed infront of the BG
i changed on to 30x30 and now its displayed behind the background.

if i use gluPerspective(...) Depth test is working fine.

do i have a mistake in my code or forgot somthing?
does anyone uses glortho in his code and its working there?

im using kos 2.0
i also used glortho with older Kos version i think 1.3 (around 15 years old)
in at this time it works
