Simplify Mesh by Amount

​

About this Block

What it does: The Simplify Mesh by Amount block simplifies an input mesh by removing elements of the mesh, until a specified percentage of triangles have been removed. The Amount input must be a number greater than 0 and less than 1. An input of 0.3 reduces the face count of the mesh by 30%. Common uses:

• Reducing the face count and file size for export

Tips:

• The decimation algorithm does not take into account a surface tolerance (the distance between any original input mesh surface and the simplified new surface).
• To simplify a mesh while maintaining a specified surface tolerance, use the Simplify Mesh by Threshold block.

Mesh, Scalar

Simplifies a Mesh by a specified target percentage, represented as a value from 0 to 1. An input of 0.1 will remove approximately 10 percent of the faces. A value of 1 will attempt to remove as many faces as possible, while still trying to preserve the general shape of the Mesh.
