Member Function Documentation

◆ getBufferType()

virtual PxBufferType::Enum physx::PxBuffer::getBufferType ( ) const
pure virtual

Buffer memory space type.

See also
PxBufferType

◆ getCudaContextManager()

virtual PxCudaContextManager * physx::PxBuffer::getCudaContextManager ( ) const
pure virtual

Get the associated PxCudaContextManager.

See also
PxCudaContextManager.

◆ map()

virtual void * physx::PxBuffer::map ( )
pure virtual

Provides access to internal memory (either device or pinned host memory depending on PxBufferType).

Unfinished operations will be flushed and synchronized on before returning.

◆ release()

virtual void physx::PxBuffer::release ( )
pure virtual

Deletes the buffer.

Do not keep a reference to the deleted instance. Unfinished operations will be flushed and synchronized on.

◆ sync()

PX_INLINE void physx::PxBuffer::sync ( )
inline

Helper function to synchronize on all pending operations.

See also
PxCudaContextManager.

◆ unmap()

virtual void physx::PxBuffer::unmap ( void *  event = NULL)
pure virtual

Releases access to internal memory (either device or pinned host memory depending on PxBufferType).

Parameters
[in]eventOptional pointer to CUevent. Used to synchronize on application side work that needs to be completed before buffer can be accessed again.
