\brief Processes a triangle mesh and makes sure that no triangle edge is longer than the maximal edge length specified
|
||
|
|
|
||
|
|
To shorten edges that are too long, additional points get inserted at their center leading to a subdivision of the input mesh.

This process is executed repeatedly until the maximum edge length criterion is satisfied

\param[in,out] triangles The triangles of the mesh where a maximum edge length should be enforced. They will be modified in place during the process.

|
|
\param[in,out] points The vertices of the mesh where a maximum edge length should be enforced. They will be modified in place during the process.
|
||
|
|
\param[in] maxEdgeLength The maximum edge length allowed after processing the input
|
||
|
|
\param[in] maxIterations The maximum number of subdivision iterations
|

|
\param[out] triangleMap An optional map that provides the index of the original triangle for every triangle after the subdivision
|

\param[in] triangleCountThreshold Optional limit to the number of triangles. Not guaranteed to match exactly, the algorithm will just stop as soon as possible after reaching the limit.
