Member Function Documentation

void btSoftBodyLinkDataOpenCL::createLinks ( int  numLinks  )  [virtual]

Allocate enough space in all link-related arrays to fit numLinks links.

Reimplemented from btSoftBodyLinkData.

Definition at line 188 of file btSoftBodySolver_OpenCL.cpp.

void btSoftBodyLinkDataOpenCL::generateBatches (  ) 

Generate (and later update) the batching for the entire link set.

This redoes a lot of work because it batches the entire set when each cloth is inserted. In theory we could delay it until just before we need the cloth. It's a one-off overhead, though, so that is a later optimisation.

Definition at line 259 of file btSoftBodySolver_OpenCL.cpp.

bool btSoftBodyLinkDataOpenCL::moveFromAccelerator (  )  [virtual]

Move data from host memory from the accelerator.

The CPU version will always return that it has moved it.

Reimplemented from btSoftBodyLinkData.

Definition at line 234 of file btSoftBodySolver_OpenCL.cpp.

bool btSoftBodyLinkDataOpenCL::moveToAccelerator (  )  [virtual]

Move data from host memory to the accelerator.

The CPU version will always return that it has moved it.

Reimplemented from btSoftBodyLinkData.

Definition at line 215 of file btSoftBodySolver_OpenCL.cpp.

bool btSoftBodyLinkDataOpenCL::onAccelerator (  )  [virtual]

Return true if data is on the accelerator.

The CPU version of this class will return true here because the CPU is the same as the accelerator.

Reimplemented from btSoftBodyLinkData.

Definition at line 210 of file btSoftBodySolver_OpenCL.cpp.

void btSoftBodyLinkDataOpenCL::setLinkAt ( const LinkDescription link,
int  linkIndex 
) [virtual]

Insert the link described into the correct data structures assuming space has already been allocated by a call to createLinks.

Reimplemented from btSoftBodyLinkData.

Definition at line 200 of file btSoftBodySolver_OpenCL.cpp.
