Thread: OpenGL Depth Problems

It draws only black. I'm almost completely sure that it's a depth problem. So this would be the code.

Code:

GLvoid ReSizeGLScene(GLsizei width, GLsizei height)	
{
	if (height==0)									
	{
		height=1;									
	}

	glViewport(0,0,width,height);						

	glMatrixMode(GL_PROJECTION);
	glLoadIdentity();							
	
	glFrustum(-1.0, 1.0, -1.0, 1.0, 0.0, 1.0);
	glTranslatef(-2.5,2.5,3.0);

	glMatrixMode(GL_MODELVIEW);					
	glLoadIdentity();							
}

int InitGL(GLvoid)							
{
	loadtexture();
	glEnable(GL_TEXTURE_2D);
	glShadeModel(GL_SMOOTH);						
	glClearColor(0.0f, 0.0f, 0.0f, 0.0f);			
	glClearDepth(1.0);								
	glEnable(GL_DEPTH_TEST);														
	return TRUE;									
}

you could try using gluPerspective...

Code:

void gluPerspective(GLdouble fovy,
                                GLdouble aspect,
                                GLdouble zNear,
                                GLdouble zFar)

gluperspective doesn't perform frustum clipping

zNear and zFar specify the distance to the near and far clipping planes. so if its a depth problem (as droid thinks it is) the near/far clipping planes could be part of it.

I thought he had glfrustum in there because he wanted frustum clipping

he can still have it..

DESCRIPTION
gluPerspective specifies a viewing frustum into the world coordinate system.

I tried changing it to perspective... it didn't change anything.

he got it fixed I gave him some help over IM.........it was just a matter of using perspective view over orthographic.....

Ah cool.
