Thread: OpenGL Problems(again)

What about drawing your text after all of your geometry has been drawn? That usually works fine for me.

I do, I'm using Nehe's 3d bitmap text. I use glprint at the way end of my DrawGLScene(). And the polygons zoom so close that for SOME reason, it still goes straight through the text!
here a copy and paste of the end of my drawglscene

Code:

	glLoadIdentity();
	glTranslatef(-1.0f,-1.2f,-1.0f);
		glNormal3f( 0.0f, 0.0f, 1.0f);
	glBegin(GL_QUADS);						// Draw A Quad
		glVertex3f(-1.0f, 1.0f, 0.0f);				// Top Left
		glVertex3f( 1.0f, 1.0f, 0.0f);				// Top Right
		glVertex3f( 1.0f,-1.0f, 0.0f);				// Bottom Right
		glVertex3f(-1.0f,-1.0f, 0.0f);	
	glEnd();
	
/*	CXPOS(-2.0f,-0.5f,-2.0f);
	CXPOS(-2.0f,2.0f,0.5f);
	CXPOS(2.0f,-0.5f,-2.0f);
	CXPOS(2.0f,2.0f,0.5f);
	CZPOS(-2.0f,-0.5f,-2.0f);
	CZPOS(-2.0f,2.0f,0.5f);
	CXPOS(-2.0f,2.0f,0.5f);
*/

		
	glLoadIdentity();


		glTranslatef(0.0f,0.0f,-1.0f);
	glColor3f(255,0,0);
	glRasterPos2f(-0.55f,-0.4);
 	glPrint("Y-ROT: %f",yrot);
	glRasterPos2f(-0.55f,-0.3);
	glPrint("X-POS: %f",xpos);
	glRasterPos2f(-0.55f,-0.35);
	glPrint("Z-POS: %f",zpos);
	
	return TRUE;

that polygon alone totally overlaps the text.
EDIT: and to avoid confusion, that polygon that covers the text can also be overlapped by another polygon zoomed in and drawn before. That's really weird, how come polygons you draw before others can still overlap as if they're the top layer?

Try just turning off depth comparisons. What you are experiencing is z-fighting. So you need to tell opengl to always draw the text and disregard that a part of a polygon is in fact closer.

glDisable( GL_DEPTH_TEST );

Just remember to re-enable it when you're done.
