Quad Reducer

For 16 years, we at Simplygon have been innovating in automated 3D content optimization. One of our recent developments is the Quad Reducer.

The Quad Reducer optimizes meshes made from quads, preserving topology after optimization. It removes entire quad strips to a specific target, maintaining topology, which is crucial for many types of assets, such as character faces. Additionally, it takes into account important features during optimization, including open edges, UVs, and normals.

The Quad Reducer shares the same reduction targets as the Triangle Reducer: triangle ratio, triangle count, max deviation, and screen size. It can also optimize assets made from both quads and triangles, with the Quad Reducer handling quad portions while the Triangle Reducer processes triangles.

Additional Simplygon features that complement the Quad Reducer include:

• Automatic Porting: Automatically porting assets to less powerful platforms by creating new LOD0 while keeping quad data.
• Mixed LOD Chains: Building a mixed Level of Detail (LOD) chain where the initial LOD levels are created with the Quad Reducer and the later ones with the Triangle Reducer.
• Artist Control: Allowing artists control over optimization by using vertex weights to preserve more geometry in important areas like character faces.

The Quad Reducer is available in the Autodesk 3ds Max plugin, Autodesk Maya plugin, and directly via the API.

Developed in collaboration with Xbox Game Studios and other global customers, the Quad Reducer is ready for evaluation. If you want to see how Simplygon’s Quad Reducer can optimize your meshes, contact us for an evaluation.
