#19 Trimesh Memory Leaks

Subject: [ODE] Re: Memory leak from dBodySetPosition()?

Trimesh has some static caches that need to be cleared.
Try adding a
function in trimesh.cpp that is called during dCloseODE.

void dClearTrimeshCaches(void)
{

dxTriMesh::defaultSphereCache.TouchedPrimitives.Empty();
dxTriMesh::defaultBoxCache.TouchedPrimitives.Empty();

dxTriMesh::defaultCCylinderCache.TouchedPrimitives.Empty();
dxTriMesh::Faces.Empty();
}

I thought I submitted a patch for this, but it turns
out I haven't.
Assuming it fixes your allocations, its probably a good
idea for this to
go in the unstable branch.

Last time I checked this was still a problem in both
branches of CVS. I need to do more research to see if it has
been fixed.

Hi,

In the unstable branch there is a fix for a memory leak.

In collision_trimesh_ccylinder.cpp

if (! Collider.GetContactStatus()) {
// no collision occurred

• delete[] gLocalContacts;
  return 0;
  }

You can check if this solves your problem.

The leak fixes described by Geoff were added in SVN #1132, I must have forgotten to close this patch at the time.
