IMO provides an efficient way to optimize complex 3D models, which originate from CAD/CAM/CAE systems and other sources, for use on the Internet. Key features: Highly complex optimization algorithms designed to maintain the visual aspects of the original object. Advanced visual support - all manipulations with optimization parameters are dynamically displayed in the 3D window. Batch and manual optimization for choice. Ability to optimize separate parts and shapes of the model. Ability to edit the models: vertex, edges or shapes editing modes are available. Ability to publish the models on the Web. Supported formats: Import VRML 1.0, VRML97, DXF v.12, Export VRML97, Support for GZIP compression.
