recalculateNormals

[ignorator]

does this normal smoothing work when recalculating the normals?

Code: Select all

man->recalculateNormals(mesh, true);

Code: Select all

man->recalculateNormals(mesh, false);

i can't see any difference on my test - sphere. it doesn't look smoothed.

This depends on the mesh file format you use. Some meshes duplicate all vertices per face, so there is no smoothing possible.

so if u wanted to smooth that normals u would have to find the vertices with equal positions and sum the triangle normals they belong to?

sounds like a slow solution.

Well, some formats will be improved so we will only split in case of different texture coords or different per-vertex normals. But also this solution is not as bad as you might think, although it's usually faster to avoid the splitting as much as possible.
