VizUp Reducer Home Professional

VizUp Professional enables you to reduce the number of polygons in a complex 3D model while retaining the quality and appearance of the original. Supports Wavefront .OBJ, VRML2 and StereoLitho (STL) file formats.

Pros: This application is able to reduce the total number of polygons used in rendering a particular 3D object model. The aim is to reduce these number of polygons so that rendering times can be reduced. Other part of the trade off is to still maintain the appearance quality of the model. It maintains well-balanced level of details and size, which is perfect for the use in virtual reality and real-time visualization systems. The application is able to pick up the required parameters required for the reduction process and does not require manual intervention. It supports Wavefront .OBJ, VRML2 and StereoLitho (STL) file formats. The program creates all the reductions at the same time. That makes it possible to look at the reduced versions and decide visually what suits your needs. There is no need to go through progressive reductions and decide on one. The user interface is simple and very easy to use. Calling up the 10, 20, 30 percent reduced model for visual inspection takes just a click on the right button. Turn around these models in all three axes and make a suitable visual judgment.

Another good thing about VizUp is its unique ability to maintain the visual fidelity of the model even at high compression ratios. The application does delete some vertices in trying to create a compressed model. But the other vertices do not change so that there are no changes in the geometry of the model. Texture mapping are not affected because of this strategy as the texture co-ordinates remain the same. Optimization techniques help with the model appearance and could be tried if the visual does not appeal to you.

Cons: No particular problem noticed.

Overall: The application is quite useful, has the necessary features and is easy to use. This is good for 4 stars easily.

VizUp Professional enables you to reduce the number of polygons in a complex 3D model while retaining the quality and appearance of the original. The end result of the reduction is a 3D model with a well-balanced level of details and size, which is perfect for the use in virtual reality and real-time visualization systems. The process of reduction is extremely simple and doesn't require any advanced knowledge. VizUp automatically picks all necessary parameters without any manual interference on your side. Supports Wavefront .OBJ, VRML2 and StereoLitho (STL) file formats.
Unique to VizUp is that it compresses the model for all possible ratios at once. This means you can see the effect of any compression level instantly with a click on the corresponding ratio button. Thanks to this, you no longer have to restart polygon reduction each time for 10%, 20%, 30%, and other ratios. Switch between different compression ratios, compare the resulting models and select the one that fits your requirements.
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. Thanks to this, there are minimal distortions during texture mapping, as texture coordinates of the vertices remain the same. However if you find that the resulting model doesn't look well, you can refine it by using the VizUp's optimization algorithm. This makes the model look very smooth.
