btGimpactTriangleMeshShapes crash when used from btBulletWorldImporter unless loadFileFromMemory is used #17

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
The way btGimpactTriangleMeshShapes are designed they do not retain ownership 
of their vertex and index data. btBulletWorldImporter currently does not create 
a run time copy of this data so once loadFile() finishes, the 
btStridingMeshInterfaceData structures used during the load are discarded and 
the btGimpactTriangleMeshShape will crash during a debugRender call or 
collision test. 

I've included a patch file that fixes this problem for the time being. It might 
be worth exploring changing the design of btGimpactTriangleMeshShapes to take 
owner ship of this data or to make its own copy of it, but this fix takes care 
of the problem in a way in tune with how btBulletWorldImporter manages data.
