DVxform_coord
Synopsis
Transform the node coordinates of a mesh according to the transform specified in the mesh. Return an array containing the transformed coordinates.

};Description
DVxform_coord takes a mesh as its input and returns an array containing the coordinates of this mesh, transformed according to the transformation matrix in the input mesh.The output is a 2D array containing the X, Y and/or Z components of the mesh's coordinates after being transformed by the mesh's transformation matrix. If X (0) and Y (1) are selected, it outputs X 0 , Y 0 , X 1 , Y 1 , and so on. Note that the output coordinates are in general not the same as the coordinates of the mesh itself; they are transformed, so they are in "world coordinates", as you would see them in the viewer, because of the transformation step.
Input
int[]. An array of up to three elements, selecting which of X, Y and/or Z to transform and output. Unselected elements are ignored. The behavior is undefined if this array has zero or more than three elements, or if the values are not in the range [0,2]. 0 selects X, 1 selects Y, and 2 selects Z.
