Rational Reducer is a 3D image file compression tool designed to help speed 3D rendering by reducing polygon count. The program greatly reduces the number of polygons used to render your 3D model, thereby improving rendering speed by as much as 90% and lowering storage requirements while retaining scalable visual quality. You can control visual quality, but polygon reduction is automatic and no parameter tuning is necessary. Rational Reducer supports VRML, AutoCAD's DXF, and 3D Studio' s 3DS formats.
