Internal error in segmentintersection():
  Topological inconsistency after splitting a segment.
  Please report this bug to jrs@cs.berkeley.edu
  Include the message above, your input data set, and the exact
    command line you used to run Triangle.

For some reasons, the original mesh file is not convenient to send to you.

Can you give me any suggestions ? Thanks a lot.

I have a question that can a texture triangle be different colors (which meaning different cameras) ? Could this situation cause the above error?

Below is an example.

In the figures above,I drew an 8*8 texture map, using different colors to represent different cameras, using black lines for texture triangles. My questions are:

• In the left Fig. a, are two texture triangles ABC and ACD a reasonable input? Can they belows to the same atlasChart ?
• In the right Fig. b, are two texture triangles EFG and EHG a reasonable input? Can they belows to the same atlasChart ?

I think the above conjecture is wrong. There is no requirement for color consistency of a texture triangle.
