build triangle mesh acceleration tree#
Build a representation of a query acceleration structure from an array of ‘points’ and an array of point indices for triangles, ‘triIndices’. The output is an opaque representation of the acceleration structure in the form of a bundle. ATTENTION!: omni.particle.system.core is currently undergoing extensive (breaking) changes. Please be aware that systems built with the existing extension will need to be rebuilt in the USD Composer 2023.2 release.
Installation#
To use this Node, you must enable omni.particle.system.core in the Extension Manager.
