Quick Surface Mesh

Surface Meshing (Generation)

Description

This Filter generates a Triangle Geometry from a grid Geometry (either an Image Geometry or a RectGrid Geometry) that represents a surface mesh of the present Features. The algorithm proceeds by creating a pair of Triangles for each face of the Cell where the neighboring Cells have a different Feature Id value. The meshing operation is extremely quick but can result in a surface mesh that is very "stair stepped". The user is encouraged to use a smoothing operation to reduce this "blockiness".

The user may choose any number of Cell Attribute Arrays to transfer to the created Triangle Geometry. The Faces will gain the values of the Cells from which they were created. Currently, the Filter disallows the transferring of data that has a multi-dimensional component dimensions vector. For example, scalar values and vector values are allowed to be transferred, but N x M matrices cannot currently be transferred.
