Frequently Asked Questions

How do advanced computational meshers compare to the visualization mesher?

The visualization and computational meshers choose different trade-offs between performance, triangle quality and memory footprint (i.e. number of polygons). The visualization mesher favors performance and lower footprint, whereas the computational meshers strive to make the highest quality (i.e. most regular) triangles.

The computational mesher uses third-party algorithms which are not thread-safe. Therefore (unlike visualization mesher), the computational meshers run single-threaded and thus take much longer times to tessellate the 3D model.

How is the Advanced meshers add-on licensed?

The Advanced meshers add-on is licensed like other CAD Exchanger SDK add-ons. Please refer to the pricing page for details.

Given that the mesh generator is a third-party code, we do not provide support for the algorithm itself. However we can try to make recommendations on preparing your models. The visualization mesher (which resides inside the SDK core) is entirely our own implementation.
