HUD implementation

Are you looking for a way to diasble lighting?
If that''s it, this is the function you need:
glDisable(GL_LIGHTING);

Remember to turn it on again after rendering your HUD:
glEnable(GL_LIGHTING);

Use the Ortho mode (look on google for glOrtho() )

thxs for the tips, found just what i wanted.

should i now be drawing 3D first after calling gluPerspective(), and 2D (hud display basically) last after calling gluOrtho2D() ?

the rest seems to work fine.

yes, and you might want to clear the depthbuffer before you start drawing your hud.

ok, everything is working fine thxs for the help.

just have a little question regarding my code. I have a feeling there are some useless things in here.

//========================================================
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

glPushMatrix();
glViewport(0, 0, width, height);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluPerspective(45.0f, width/height, 1.0f, 100.0f);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

// draw 3D scene.

glPopMatrix();

glPushMatrix();

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(0.0f, width, 0.0f, height);
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();

// draw HUD.

glPopMatrix();
//========================================================

is this code correct (it seems to work fine) or are there some useless calls i am making ?

thxs again for all the help ^^


Jesus is coming! (look busy)
