Member Function Documentation

static void* CE_VDBGrid::allocAlignedBufferFromVDB ( const openvdb::GridBase &  grid, exint &  size  )

static

Builds a CPU buffer from the VDB provided: The result is SYSamalloc so must be SYSafreed.

const cl::Buffer& CE_VDBGrid::buffer ( ) const

inline

Return the underlying OpenCL buffer that can be used in kernel invocations.

static void CE_VDBGrid::buildTileStartsArray ( UT_Array< UT_Vector3i > &  starts, exint &  leafcount, exint &  lowercount, exint &  uppercount, const openvdb::GridBase &  grid  )

static

Utility function to build an tilestart array from a grid.

static void CE_VDBGrid::buildTileStartsArray ( UT_Array< UT_Vector3i > &  starts, exint &  leafcount, exint &  lowercount, exint &  uppercount, const CE_BufferHostByte &  cpugrid  )

static

Utility function to build an tilestart array from a nanovdb on cpu.

void CE_VDBGrid::copy	(	const CE_VDBGrid &	src,
		bool	readsrc = true
	)

Deep copy from another grid into this, if readsrc is false, will only allocate matching size.

openvdb::GridBase::Ptr CE_VDBGrid::createVDB

(

)

const

Create a VDB grid from the CE VDB grid.

static openvdb::GridBase::Ptr CE_VDBGrid::createVDBFromAlignedBuffer ( const void *  data, exint  datasize  )

static

Create a VDB grid from generic memory. NanoVDB requires 32 byte aligned buffers.

exint CE_VDBGrid::getDeviceMemoryUsage ( ) const

inline

Definition at line 44 of file CE_VDBGrid.h.

bool CE_VDBGrid::hasBuffer ( ) const

inline

If the current OpenCL buffer is valid.

Definition at line 57 of file CE_VDBGrid.h.

void CE_VDBGrid::initFromBuffers	(	const void *	data,
		exint	datasize,
		UT_VDBType	storagetype
	)

Initialize from a memory pointer and size. This will blocking-write to GPU data.

void CE_VDBGrid::initFromDeviceBuffers	(	cl::Buffer	gridbuffer,
		exint	gridsize,
		UT_VDBType	storagetype
	)

Initialize the CE_VDBGrid from the supplied buffers of a nanovdb.

void CE_VDBGrid::initFromSize	(	exint	datasize,
		UT_VDBType	storagetype
	)

Initialize from a given size, allocating only assuming later code will write to it..

void CE_VDBGrid::initFromVDB

(

const openvdb::GridBase &

grid

)

Initialize the CE_VDBGrid from the supplied VDB grid.

void CE_VDBGrid::updateTransform	(	const UT_Matrix3D &	xform,
		const UT_Vector3D &	center,
		const UT_Vector3D &	voxelsize,
		double	taper
	)

Replaces the map transform with the provided one.
