Overlaps Pair0 (inputs:overlapsPair0)

token[]

Path of the first geometry from the Prims Bundle to check for penetration with corresponding item at same index in overlapsPair1 input attribute.

[]

Overlaps Pair1 (inputs:overlapsPair1)

token[]

Path of the second geometry from the Prims Bundle to check for penetration with corresponding item at same index in overlapsPair0 input attribute

[]

Prims Bundle (inputs:primsBundle)

bundle

The prims of interest. It must be a bundle with one or more prim children. Currently only meshes prim are supported (sourcePrimType == ‘Mesh’). Penetration vectors are not computed when both sides of a pair use triangle mesh approximation. Penetration computation only works if the (optional) ‘physics:approximation’ of one of the two overlap pair to check is not ‘triangle mesh’ (can be ‘convex mesh’). From each Mesh prim child reads: - ‘sourecePrimPath’ - ‘sourcePrimType’ - ‘points’ - ‘faceVertexIndices’ - ‘faceVertexCounts’ - ‘worldMatrix’ - ‘sourcePrimPath’ (and optionally ‘holeIndices’, ‘orientation’, ‘meshKey’ and ‘physics:approximation’) attributes

None

Overlaps (outputs:overlaps)

bool[]

Array of booleans where ‘True’ value signals that a corresponding pair of meshes in overlapsPair0 and overlapsPair1 input arrays at the same index do actually overlap.

None

Penetration Depths (outputs:penetrationDepths)

float[]

Array of penetration depths values of the corresponding pair of meshes in overlapsPair0 and overlapsPair1 input arrays at the same index.

None

Penetration Vectors (outputs:penetrationVectors)

normalf[3][]

Array of penetration normals of the corresponding pair of meshes in overlapsPair0 and overlapsPair1 input arrays at the same index.
