Hello,
I got this code that draws a textured wall of a brick house
glBegin(GL_QUADS);
glTexCoord2f(0.0, 1.0); glVertex3f(x,y,z); // TL
glTexCoord2f(0.0, 0.0); glVertex3f(x,y,z); // BL
glTexCoord2f(1.0, 0.0); glVertex3f(x,y,z); // BR
glTexCoord2f(1.0, 1.0); glVertex3f(x,y,z); // TR
glEnd();
If I want to put a window or door in that wall defined by GL_QUADS, what woudl be the best way to do it. Another GL_QUADS,glScissor, or alpha testing?
Thanks
