void btSoftBodyLinkDataOpenCLSIMDAware::createLinks ( int numLinks )

virtual

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

Reimplemented from btSoftBodyLinkData.

Definition at line 95 of file btSoftBodySolver_OpenCLSIMDAware.cpp.

void btSoftBodyLinkDataOpenCLSIMDAware::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.
