void	setToDefault ()
	Desc initialization to default value.

bool	isValid () const
	Returns true if the descriptor is valid.

Public Attributes
PxU32	numPrimsPerLeaf
	Mesh cooking hint for max primitives per leaf limit. Less primitives per leaf produces larger meshes with better runtime performance and worse cooking performance. More triangles per leaf results in faster cooking speed and smaller mesh sizes, but with worse runtime performance.

PxBVH34BuildStrategy::Enum	buildStrategy
	Desired build strategy for the BVH.

bool	quantized
	Whether the tree should be quantized or not.

inline

Returns true if the descriptor is valid.

Returns: true if the current settings are valid.

Member Data Documentation

◆ buildStrategy

PxBVH34BuildStrategy::Enum physx::PxBVH34MidphaseDesc::buildStrategy

Desired build strategy for the BVH.

Default value: eDEFAULT

◆ numPrimsPerLeaf

PxU32 physx::PxBVH34MidphaseDesc::numPrimsPerLeaf

Mesh cooking hint for max primitives per leaf limit. Less primitives per leaf produces larger meshes with better runtime performance and worse cooking performance. More triangles per leaf results in faster cooking speed and smaller mesh sizes, but with worse runtime performance.

Default value: 4 Range: <2, 15>

◆ quantized

bool physx::PxBVH34MidphaseDesc::quantized

Whether the tree should be quantized or not.

Quantized trees use up less memory, but the runtime dequantization (to retrieve the node bounds) might have a measurable performance cost. In most cases the cost is too small to matter, and using less memory is more important. Hence, the default is true.

One important use case for non-quantized trees is deformable meshes. The refit function for the BVH is not supported for quantized trees.

Default value: true
