Houdini 20.5 Nodes Copernicus nodes

Mono to SDF Copernicus node

Computes a Signed Distance Field from an iso-level of a Mono layer.

On this page

This operation builds a signed distance field storing distance to where a Mono layer crosses a a value.

Parameters

Invert

Normally values greater than the iso value are considered inside, so get negative distances, and values less than the iso value are outside, so given positive distances. This inverts the sign.

Iso

The threshold to consider the boundary of the signed distance value.

Iterations

A single iteration is sufficient to converge if there is a uniform speed field. But if the speed varies in complicated fashions, it may require more passes for the distances to fully propagate.

Tile Size

The layer is broken up into blocks of this size. This helps balance the serial and parallel components of the algorithm. If it has converged, this should have no effect on the behaviour. The default values should be sufficient.

Inputs

mono

A Mono layer. An isocontour of this will be used to compute distances.

Outputs

sdf

The signed distance to an isocontour of the mono input.
