It is well known that it is not easy to develop a mature 3D graphics
framework with high interactive performance for CAD/CAM field, just like
HOOPS.
Although we can make one using Mesa3d or OpenGL, but full-featured 3D
engine for CAD need lots of endeavor.
I want to know whether there is a opensource 3D framework based on
OpenGL/Mesa3d whose function, operation is like HOOPS-3D.
there are numberless as the sand 3D framework in the opensource realm,
however,most of them are focused on realistic rendering.
HOOPS is focused on:
1:high-performance rendering(non-realistic);
2:high-performance interaction(e.g picking object);
3:can convert some high-level entity to graphics primitives.(for
example, HOOPS can dispose ACIS entity directly).
4:....easy to use ...
does anyone have any idea?
thanks a lot.
