Dear all,
I am developing an application that allows to apply geometry
deformations vertex by vertex. For doing this, I manage a list with the
vertex indices of a geometry node. That is, for example I translate the
vertex 5th independently of the rest of vertices (but maintaining the
geometry faces connectivity and the colors and materials).
I am working with obj files which I load using the OSG obj
loader, and manage the indices through the VertexArray of the Geometry node.
I have seen if I have a obj file linked to a mtl file with different
materials (using usemtl commands in the obj file), OSG breaks the geometry
in different nodes, one per material, even if it is a unique mesh. Is there
any possibility for avoiding it? That is, having an unique and complete mesh
for all the closed geometry in the file?
Thank you in advance!
Best,
David.
