I want to export OCC geometries to Open Inventor.
Therefor i use the OCC_COIN3D-viewer interface.
By exporting OCC exports each face of the shape as a SoIndexedTriangleStripSet.
It's no problem to merge the faces to a shape (IndexedTriangleStripSet) but:
The directions of the faces are always "wrong" - faces are directed along the pos. x, y, and z- axis but should be directed "outside" the shape.
Could anybody tell me howto analyse face directions of a shape - is there any function I didn't see till now (in OCC)
thank you for your support
