Polygon Cruncher is also available through a SDK for developers. Look at the differences between these versions.

Polygon Cruncher reduces the number of polygons of your objects without changing their appearance. You keep all details even at high optimization ratio. You also keep texture information, vertex colors, user defined normals. You protect object borders, material boundaries, UVs seams... You can optimized taking care of the symetry of your objects.

Polygon Cruncher has an OpenGL view which allows controlling optimization results whenever you want.

Moreover, Polygon Cruncher features batch processing: select the optimization levels you wish and let's go! You optimize one or more scenes at different levels in a single step.

Polygon Cruncher uses an exceptional algorithm developed since 10 years, which gives incomparable results, really better than what you can get with optimizer provided with 3DS Max or Lightwave.

Polygon Cruncher is really simple to use. It has been chosen by major 3D companies: Autodesk, Anark, Activision, Epic Games, Airbus, Boeing, Sega, Sony, 3DO, Digital Domain, Kalisto...
