Balancer is a fast, efficient and easy to use tool for optimizing 3D polygonal models. With Balancer you can quickly and easily find your perfect balance between visual appearance and the number of polygons. Balancer utilizes a high quality polygon reduction (aka mesh simplification) to preserve the visual appearance of your model. The model features, normals, texture coordinates, layer boundaries are all honored.
Balancer utilizes a high quality, high performance polygon reduction (aka polygon simplification or decimation) to preserve the visual appearance of your model. Polygon reduction is computed for all possible levels of detail (LOD) in one shot. This entire LOD hierarchy allows you instantly pick a required optimized model that gives the best trade-off between visual appearance and the number of triangles.
Rendering Performance Optimization
Modern graphics hardware and rendering applications utilize memory and vertex cache to dramatically speed up rendering and geometry processing. To make your models benefit from this, Balancer features a fast and efficient triangle reordering.

Optimize your models even further to dramatically speed up rendering of your models. Balancer features a fast and efficient triangle reordering that can be tuned for various rendering methods like triangle strips and array/buffer based rendering.

Balancer accurately preserves and optimizes all types of boundaries defined by the model attributes. However, absent or excessive boundaries may dramatically deteriorate the visual appearance and optimization quality of the resulting 3D models. Thus, before optimizing your model, it is important to inspect its boundaries and repair it if necessary.
Balancer recognizes the following 4 types of boundaries:
* Surface boundaries
* Normal boundaries
* Texture coordinates (UV) boundaries
* Material or layer boundaries

Modern graphics hardware and rendering applications utilize memory and vertex cache to dramatically speed up rendering and geometry processing. To make your 3D models benefit from this, select export settings to optimizes your models depending on your rendering method.

Balancer Lite is a free version. It is fully functional but works with small meshes only.
The limits for a single mesh are 15000 triangles and 10000 vertices.

If your entire model is large but has many small independent meshes or layers, you can still use Balancer Lite. Before loading your model, enable Balancer to split the model into independent meshes in Tools | Options | Importers | Wavefront .obj.
Balancer Lite can be used for non-commercial purposes in non-business, non-commercial environment only. Commercially, 30 days evaluation period applies.
