Tessellation

[mylee]

when import step file, i feel it automatically tessellate
and i can control level of tessellation with angular deflection and linear deflection

i wonder what kinds of algorithm is used and where can i find it in source code(ex. xxx.cpp or xxx.h)
also there are any function to control tessellation sophistically in Analysis Situs
if there are no in Analysis Situs, in opencascade?

thank you

I guess you're looking for asiVisu_ShapeRobustSource.h/cpp class. https://gitlab.com/ssv/AnalysisSitu...es/asiVisu_ShapeRobustSource.h?ref_type=heads

Since ASitus uses VTK as a rendering engine, its tesselator isn't that is used in Occt.
