Public Attributes
PxVec3	mMeshLower
	Lower bound of the original mesh.

PxReal	mSpacing
	Spacing of each sdf voxel.

Dim3	mDims
	Dimension of the sdf.

PxU32	mNumSdfs
	Number of sdf values.

PxReal *	mSdf
	Array of sdf.

PxU32	mSubgridSize
	The number of cells in a sparse subgrid block (full block has mSubgridSize^3 cells and (mSubgridSize+1)^3 samples). If set to zero, this indicates that only a dense background grid SDF is used without sparse blocks.

PxU32	mNumStartSlots
	Array length of mSubgridStartSlots. Only used for serialization.

PxU32 *	mSubgridStartSlots
	Array with start indices into the subgrid texture for every subgrid block. 10bits for z coordinate, 10bits for y and 10bits for x.

PxU32	mNumSubgridSdfs
	Array length of mSubgridSdf. Only used for serialization.

PxU8 *	mSubgridSdf
	The data to create the 3d texture containg the packed subgrid blocks. Stored as PxU8 to support multiple formats (8, 16 and 32 bits per pixel)

Dim3	mSdfSubgrids3DTexBlockDim
	Subgrid sdf is layed out as a 3d texture including packed blocks of size (mSubgridSize+1)^3.

PxReal	mSubgridsMinSdfValue
	The minimum value over all subgrid blocks. Used if normalized textures are used which is the case for 8 and 16bit formats.

PxReal	mSubgridsMaxSdfValue
	The maximum value over all subgrid blocks. Used if normalized textures are used which is the case for 8 and 16bit formats.

PxU32	mBytesPerSparsePixel
	The number of bytes per subgrid pixel.
