hi, everyone! i want to ask about colour overlapping problem. i use opengl to write a Solid Icosahedron and filled it with yellow. then i placed a cube which is green in colour which center is on the boundary of the Icosahedron. an expected happened~~ the cube is over the Icosahedron, which mean green is placed above the yellow. but i want it to show yellow over green. how can i do this?? plz help me. thanks a lot!! /--------\ |----------/-- \ |green / | yellow\ |--------/-^-| \ \ | / \| / |\---------/ | i want this is yellow, not green

Please, place your diagram inside tags. That way it will look how you intended it.

you need to write
before the drawing and just after, just without the spaces between the word "code" and the brackets.

If the center of the cube is on the edge of the icosahedron, then one of the faces of the cube will be in front of it. Thus, you''ll get green in front of yellow.

I''m a bit confused as to why that''s not what you''re expecting.
