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 node builds a signed distance field storing distance to where a mono layer crosses a value.

Parameters

Invert

Inverts the sign. Values greater than the iso value are usually considered inside and have negative distances. Values less than the iso value are usually considered outside and have positive distances.

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. If the speed varies in complicated fashions, it may require more passes for the distances to fully propagate.

Tile Size

The size of the blocks to break the layer up into.

This helps balance the serial and parallel components of the algorithm. If it has converged, this should have no effect on the behavior. The default values should be sufficient.

Inputs

mono

The original mono layer. An isocontour of this computes the distances.

Outputs

sdf

The signed distance to an isocontour of the mono input.
