All,
With my tetrahedron example I have the following completely different color
scheme.
colorData=: 1&fc ,1,"1~_3]\3#"2] 0&". ;._2 [ 0 : 0
1 0 0
0 1 0
1 1 1
0 1 1
)
This color scheme uses length 4 vectors instead of length 3 vectors:
glVertexAttribPointer colorAttr; 4; GL_FLOAT; 0; 0; 0
The good news is that I see 4 different faces but the bad news is that they
are SCREWY.
The red and the white face CROSS.
The other faces don't make sense either.
I can't figure this out at all.
By the way, I figured an alternative definition for the vertex data,
but it does no better than the original tetrahedron vertexData.
vertexData=: 1&fc ,1 2 0 0 2 3 3 2 1 1 0 3{4 3$, %&10, 0&". ;._2 [ 0 : 0
_3 _9 _4
3 _9 _4
0 0 2
0 8 _4
)
Please play with this and help.
