#13 Mesh is empty after removal of degenerated primitives

[Dario Accornero]

I have posted a .ply (Stanford Polygon Library) file that produces the error shown in the title, using r754 on Windows and Mac OS X:

http://tng3d.com/software/test/bun000.zip

This file has been imported successfully via other libraries; it is a valid .ply file. I could not attach it directly because it weighs 364KB which is over the artifact attachment limit.

Import options:

aiProcess_RemoveComponent
aiProcess_LimitBoneWeights
aiProcess_TransformUVCoords
aiProcess_Triangulate
aiProcess_JoinIdenticalVertices
aiProcess_RemoveRedundantMaterials
aiProcess_SortByPType
aiProcess_GenUVCoords
aiProcess_GenSmoothNormals
aiProcess_FindInvalidData
aiProcess_ValidateDataStructure
aiProcess_FindDegenerates
aiProcess_OptimizeMeshes

Import settings:

ms_pkImporter->SetPropertyFloat(AI_CONFIG_PP_GSN_MAX_SMOOTHING_ANGLE,
45.0f);
ms_pkImporter->SetPropertyInteger(AI_CONFIG_PP_FD_REMOVE,1);
const int iRemoveComponents =
aiComponent_COLORS | aiComponent_TANGENTS_AND_BITANGENTS;
ms_pkImporter->SetPropertyInteger(AI_CONFIG_PP_RVC_FLAGS,
iRemoveComponents);
