Member Function Documentation
◆ AddTriangle() [1/2]
|
virtual |
Add a triangle, by passing a ChTriangle object (that will be copied, not referenced).
Note: the vertexes must be properly ordered (oriented triangle, normal pointing outside)
◆ AddTriangle() [2/2]
|
pure virtual |
Add a triangle, by passing three points for vertexes.
Note: the vertexes must be properly ordered (oriented triangle, normal pointing outside)
Implemented in chrono::ChConvexDecompositionHACDv2, and chrono::ChConvexDecompositionHACD.
◆ AddTriangleMesh()
|
virtual |
Add a triangle mesh, by passing an entire ChTriangleMesh object.
Note: the triangles must define closed volumes (holes, gaps in edges, etc. may trouble the decomposition)
Reimplemented in chrono::ChConvexDecompositionHACDv2, and chrono::ChConvexDecompositionHACD.
◆ WriteConvexHullsAsChullsFile()
|
virtual |
Write the convex decomposition to a ".chulls" file, where each hull is a sequence of x y z coords.
Can throw exceptions.
◆ WriteConvexHullsAsWavefrontObj()
|
pure virtual |
Save the computed convex hulls as a Wavefront file using the '.obj' fileformat, with each hull as a separate group.
May throw exceptions if file locked etc.
Implemented in chrono::ChConvexDecompositionHACDv2, and chrono::ChConvexDecompositionHACD.
