Public Members

PxBoundedData bounds#: Pointer to first bounding box.

float enlargement#

Bounds enlargement.

Passed bounds are slightly enlarged before creating the BVH. This is done to avoid numerical issues when e.g. raycasts just graze the bounds. The performed operation is:

extents = (bounds.maximum - bounds.minimum)/2 enlagedBounds.minimum = passedBounds.minium - extents * enlargement enlagedBounds.maximum = passedBounds.maxium + extents * enlargement

Users can pass pre-enlarged bounds to the BVH builder, in which case just set the enlargement value to zero.

Default value: 0.01

PxU32 numPrimsPerLeaf#

Max primitives per leaf limit.

Range: [0, 16)Default value: 4

PxBVHBuildStrategy::Enum buildStrategy#
