For starters, VTK is written using the OpenGL API.

Secondly, VTK sucks for general purpose 3D graphics.

Thirdly, VTK leaks memory left and right with the misuse of even 1 parameter.

Fourthly, VTK is object oriented and complex.

Fifthly, VTK is used primarily for visualization applications (ie: industrial/scientific apps).

And finally, VTK is primarily written for the Unix community - their Win version support sucks bigtime.

Thats all.
