Member Function Documentation

void btSoftBodyTriangleDataOpenCL::createTriangles ( int numTriangles )

virtual

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

Reimplemented from btSoftBodyTriangleData.

Definition at line 405 of file btSoftBodySolver_OpenCL.cpp.

void btSoftBodyTriangleDataOpenCL::generateBatches ( )

Generate (and later update) the batching for the entire triangle 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 461 of file btSoftBodySolver_OpenCL.cpp.

bool btSoftBodyTriangleDataOpenCL::moveFromAccelerator ( )

virtual

Move data from host memory from the accelerator.

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

Reimplemented from btSoftBodyTriangleData.

Definition at line 442 of file btSoftBodySolver_OpenCL.cpp.

bool btSoftBodyTriangleDataOpenCL::moveToAccelerator ( )

virtual

Move data from host memory to the accelerator.

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

Reimplemented from btSoftBodyTriangleData.
