void Geometry::computeNormals ( bool verbose = false )

Computes the normals in a "smooth" way, i.e.

averaging the normals of those polygons that share one or more vertices.

This function computes smoothed normals for triangle primitives and leaves unchanged the normals of line and point primitives when possible, i.e. when they don't share vertices with the polygonal primitives.

Note:: This function modifies the local buffers. After calling this you might want to update the buffers allocated on the GPU.
