Houdini 20.5 Nodes APEX nodes

geo::InitIntersectCache

Computes an intersection cache for a geometry.

On this page
Since 20.0

An intersection cache is a data structure that is used for fast geometry lookups. Once created, it can be reused multiple times in different operations such as geo::Intersect, geo::IntersectPoints, and geo::AttribIntersectPoints. The use of an intersection cache in these nodes result in a speed-up in their operations. Outside of these nodes, intersection caches have little usage.

The geo ports of this node are in-place ports, which means that the geometry is updated without creating a copy.

Inputs

*geo: Geometry Required

The geometry to compute the intersection cache for.

Outputs

*geo: Geometry

The geo input, unmodified.

icache: ApexIntersectCache

The computed intersection cache.
