AFAIK The idea of a solid modeling kernel is generaly that it i some form
of
solid modeling engine prduced by a separate developer (& generally used in
many other CAD products - eg. ACIS, Parasolid). The basis for this tends
to
be that it is a lot easier (particularly for smaller developers) to
license
this part of their program rather than having to write it from scratch
then
optimise it & debug it. It also provides a certain level of ex****t
capability between other programs that use the same kernel.
Kernels will generaly have some form of API - It would e hard to
incor****atethem into other products otherwise) however the APIs only deal
with the geometry & solid modeling operations such as cutting solids etc.
(not with the presentation on the screen - which is what the APIs like
OpenGL are doing.)
