VizUp Standard
VizUp 2 is an ad hoc polygon reduction and optimization system that enables you to reduce the number of polygons in a complex 3D model and optimize its geometry. The end result of such compression is a model with a well-balanced level of details and size, which can be used in virtual reality and... Another good thing about VizUp is its unique ability to maintain the visual fidelity of the model even at high compression ratios. ... In compressing a model, VizUp deletes some vertices, but the coordinates of the remaining vertices do not change.
