Description
Octree.fromGraphNode()
has several issues right now. It does not compute the world matrices of 3D object correctly and also performs too many redundant computations. Besides, geometries are cloned beforetoNonIndexed()
is used although this is not necessary (since the method already creates a new geometry). AndfromGraphNode()
directly accesses thearray
property of buffer attributes which should never be done (since interleaved data are not supported that way).
