[fixed]PLY loader calculate normals

[kaos]

I load a ply model and draw the normals, always I get 0,1,0

Yes, in case your model does not contain normal information, this seems to become the result. I will add a recalculation. For now, simply call recalculate normals after checking if your normals are all (0,1,0)

Ok normals ok, but if a createmeshwithtangents from ply, the model crash, there are a problem with indexbuffer.

createtriangleselector not work with dynamic mesh buffer ?
