OpenGL Wrapper in .Net -

this question similar the 1 here. feel answers recommended ( such tao , opentk) not enough because direct port opengl, no oop design, , hard use.

what i'm looking .net opengl wrapper written in clear oop principles, easy use ( easy apply textual , lighting, easy debug etc), able rotate 3d diagram mouse ( feature critically missing opengl , tao), , ability export other file formats ( such dwg or dxf or google map file format).

any suggestion? both open source or commercial components do.

while correct oop wrapper possible, truth need understand how opengl works first (this true of wrapper api, , doubly opengl). since find opengl api hard use, don't understand rendering enough use wrapper api either.

most wrappers avoid heavy class frameworks because storing state each object , sending gpu each object inefficient , can kill frame rate. you, programmer, need aware of these pain points, not try hide them behind abstract wrapper layer. library designer can't solve them you.
