I'm new to OpenGL, and I've been going through NeHe's tutorials and various other web sources, and I'm testing some things to render text as a HUD of sorts over everything else. After a very long night, I can't get this to work and I can't find any solutions here that work, so I thought I'd ask.
My code:
GLvoid glLoadHUD(GLvoid)
{
glPushAttrib(GL_LIGHTING_BIT |
GL_DEPTH_BUFFER_BIT |
GL_TEXTURE_BIT);
glDisable(GL_LIGHTING);
glDisable(GL_DEPTH_TEST);
glDisable(GL_TEXTURE_2D);
glMatrixMode(GL_PROJECTION);
glPushMatrix();
glLoadIdentity();
glOrtho(0.0f, 1.0f, 0.0f, 1.0f, -1.0f, 1.0f);
glRasterPos2f(0.1f, 0.6f);
glColor3f(1.0f,1.0f,1.0f);
glPrint("Test.");
glRasterPos2f(0.0f, 0.0f);
glPopMatrix();
glMatrixMode(GL_MODELVIEW);
glPopAttrib();
glEnable(GL_TEXTURE_2D);
glEnable(GL_LIGHTING);
glEnable(GL_DEPTH_TEST);
}
Which is the code to render the text, and this is the code for drawing the scene:
int DrawGLScene(GLvoid)
{
glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); // Clears buffers
glLoadIdentity();
// If I put glLoadHUD(); here, it renders but the models render over it,
// which is useless.
for (xloop = 0; xloop < 3;)
{
glLoadIdentity();
glTranslatef(-4.0f+(float(xloop)*4.0f),0.0f,-12.0f);
glCallList(dlstBox); // This is the call to create a box.
xloop++;
}
glLoadHUD(); // If I put it here though, it doesn't render at all.
return TRUE;
}
Thank you in advance for any help you could give, I know I'm pretty green and I'm sure it's staring me right in the face, but this is driving me mad and I'm not sure how to make it work.
