SITUATION



I have this peace of code here for my "3d-mesh"



 <MeshGeometry3D 
Positions="0 0 0
0 1 0
1 0 0
1 1 0"
TriangleIndices="0 2 1
2 3 1" >
</MeshGeometry3D>


PROBLEM/QUESTION



why i can not use other vertices for creating triangles
=> i mean whenever i try to write 0 , 1 , 2 , 2 , 3 , 1 insead of 0 , 2 , 1 , 2 , 3 , 1 i cant see 1st triangle.



EDIT



here are pictures of my examples. (maybe helpful if you want to imagine the situation)



Example 1 : 0 , 2 , 1 , 2 , 3 , 1



enter image description here



Example 2 : 0 , 1 , 2 , 2 , 3 , 1
