I have a quad and I would like to use the gradient it produces as a texture for another polygon.
glPushMatrix();
glTranslatef(250,250,0);
glBegin(GL_POLYGON);
glColor3f(255,0,0);
glVertex2f(10,0);
glVertex2f(100,0);
glVertex2f(100,100);
glVertex2f(50,50);
glVertex2f(0,100);
glEnd(); //End quadrilateral coordinates
glPopMatrix();
glBegin(GL_QUADS); //Begin quadrilateral coordinates
glVertex2f(0,0);
glColor3f(0,255,0);
glVertex2f(150,0);
glVertex2f(150,150);
glColor3f(255,0,0);
glVertex2f(0,150);
glEnd(); //End quadrilateral coordinates
My goal is to make the 5 vertex polygon have the gradient of the quad (maybe a texture is not the best bet)
Thanks
