[Imstk-developers] Clearing surface mesh data on intialization

[Milef, Nicholas Boris]

No, I don't. I need to preserve the original normals that ASSIMP imports because ASSIMP calculates the normals correctly. Otherwise, I can't identify the UV seams.

I can just do this computation in the SurfaceMeshRenderDelegate, but I'm not sure if the normals are used elsewhere after reinitializing the meshes. But isn't reinitializing a mesh dangerous in a multithreaded environment anyway?

It could be used in some cases depending on the scenario. Do you plan to call this at every frame?

Is that a useful use case though? Why not just make a new mesh?

Hi Nick,
            This is cleared in case one wants to reinitialize the mesh with a different data. Initialize should only be called at initilization or at runtime if the mesh data itself changes.

I'm modifying the SurfaceMesh class currently, but why is all the data cleared on initialization? Is this necessary? I ask because I need this data to correct for the normals seams.
