Document animation : Performance issue

[NormandC]

I also think that an abstraction layer to the underlying 3D Engine OpenCascade should be introduced to be able to:

FreeCAD does not use OCC's "3D Engine", that's gaming speak. In CAD it's called a geometric modeling kernel, or sometimes CAD kernel.

https://en.wikipedia.org/wiki/Geometric_modeling_kernel

- eventually replace OpenCascade by other 3D engine bringing better performances and having less glitches

There is no other open source kernel available than OCC. CGAL doesn't count, it's a library of algorithms mainly for mathematical purposes, not a true CAD kernel. What would be the point of this work then, to plan for a hypothetical new open source kernel that may never come? FreeCAD remains a project supported by an extremely small group of dedicated frequent volunteers, surrounded by a larger group of occasional volunteers. This would be a gigantic work even for a company with full-time paid programmers. IMO what you are suggesting is unrealistic.

I agree 3D Engine was not the accurate word.

Nevertheless it does not change my view on the need of optimization, restructuring etc.

It is your baby and I am probably not the one to tell you how to grow it, grow it as you want! Sorry for that.

Forget then my thoughts. The problem brought here is a matter of performances. What is your proposal? What can be done to improve performances?

End of the discussion as far as I am concerned!

It's not. I'm pointing out that wishful thinking is pointless.
