### **Simplification**
* * * * *
**Description**：
Surface mesh simplification is the process of reducing the number of faces used in a surface mesh while keeping the overall shape, volume and boundaries preserved as much as possible. It is the opposite of subdivision.
**Input**：
Geometry: Input a Geometry.
Aspect: Aspect Ratio.
NormalDeviation: Normal Deviation.
TargetPercentage: Target Percentage ( 0 - 1 ).
**Output**：
Mesh: Output the mesh.
