How to use SolidWorks API to draw mesh and iso-contour?

[rachel]

I try to use OpenGL to draw my mesh and iso-contour result
in SolidWorks API Notification function, named BufferSwap().

Though SolidWorks API don't wrap OpenGL.
But I still can't use glColor*() function, except glMaterial*().
It's really not efficient.

Is there any other way or place to handle this?

Best regards,
Rachel
