    Texture Mapping Trouble With Opengl

    I've been working on this all day... except for Russia: Land of the Tsars and a few games of halo. I used the base code from Nehe and created the multiple texture loading etc. Anybody know what's wrong here, because I sure don't... and I'm beginning to hate these smiling... smiley faces.

    You were calling the wrong texturing funcitons

    This is what I changed to get it working correctly

    Code:
    	glBegin(GL_QUADS);
    	glTexCoord2f(0, 1);
    	  glVertex3f(-0.5, 0.5, 0.0);
    
    	glTexCoord2f(1, 1);
    	  glVertex3f(0.5, 0.5, 0.0);
    
    	glTexCoord2f(1, 0);
    	  glVertex3f(0.5, -0.5, 0.0);
    
    	glTexCoord2f(0, 0);
    	  glVertex3f(-0.5, -0.5, 0.0);
    	glEnd();

    Nevermind... the second smiley face comes up... but not the first one. I'll check the bmp file.

    what do you mean didn't change anything...that fixed it...instead of the upside down smiley face patched twice on the polygon you've got one right side up smiley face...

    True

    It did fix the smiley face... and as I look back at the tutorial that seems right... but the other image doesn't come up when I change the number.

    Thanks all

    Now I know why they're smiling... I figured that I had to call:

    Code:
    glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MIN_FILTER,GL_LINEAR);
    			glTexParameteri(GL_TEXTURE_2D,GL_TEXTURE_MAG_FILTER,GL_LINEAR);
    this for each texture. ::smacks forhead:: Anyway, thanks for all your help.
