Houdini 16.5 Nodes VOP nodes

Wave Vector VOP node

Computes the wave vector for a given index in a grid of specified size.

This operator computes wave vectors useful for generating values to be processed by the Volume FFT SOP. It generates wave vectors for the index specified within a grid of the specified resolution. The wave vectors are assumed to be periodic over the specified grid size.

The low frequency wave vectors will be in the center of the grid, so if the results are passed to Volume FFT, Center DC should be enabled on that node.

Specifying a 2D output will set the proper axis to zero.
