vertex deallocation

[ignorator]

Hi

I'm copying vertices from a mesh to a new structure.

the mesh is loaded like this:

Code: Select all

scene::IAnimatedMesh* testmesh = smgr->getMesh("../../media/test.3ds");

now I want to get rid of the old vertices in the testmesh.
When I call

Code: Select all

delete testmesh

I think the vertices remain in memory. Must I delete each vertex manually (by iterating through the vertex-buffers) ?

example from collision tutorial:

Code: Select all

// program using 9.272 K
scene::IAnimatedMesh* q3levelmesh = smgr->getMesh("20kdm2.bsp");
// program using 17.884 K
delete q3levelmesh;
q3levelmesh = 0;
// program using 14.960 K

memory leak?

You should never call a delete on a pointer pointing to a mesh or a scenenode handled by irrlicht. Always call a ->drop(); See IUnknown for details.

A handle to the mesh will still be in the mesh cache, so you need to remove it from there. Once you've removed it from the cache, and you drop your handle to the mesh, the memory usage should almost go back to the original state.

You only want to drop a handle if you have grabbed it. If you are removing meshes from the cache, then you should be grabbing them.

I have looked at IUnknown. The comment said one sould only call drop() if the pointer was initialised via a createSomething().... method...

thx removing it from the cache helped.
