Detailed Description

This class provides the interface to control memory budget and the number of SPUs used in a specific phase.

Member Function Documentation

static PX_PHYSX_CORE_API PxU32 PxPS3Config::getSceneParamInt	(	PxScene &	scene,
		PxPS3ConfigParam::Enum	param
	)

static

Returns the current value of a parameter for the given scene.

Parameters

[in]	scene	A pointer to the PxScene.
[in]	param	The parameter whose value will be returned.

static PX_PHYSX_CORE_API void PxPS3Config::getSpuMemBlockCounters	(	PxScene &	scene,
		PxU32 &	numNpContactStreamBlocks,
		PxU32 &	numNpCacheBlocks,
		PxU32 &	numDyFrictionBlocks,
		PxU32 &	numDyConstraintBlocks
	)

static

Returns a recommendation for SPU memory block settings.

Parameters

[in]	scene	A pointer to the PxScene.
[out]	numNpContactStreamBlocks	The minimal recommended value for eMEM_CONTACT_STREAM_BLOCKS used in narrow phase.
[out]	numNpCacheBlocks	The minimal recommended value for eMEM_NP_CACHE_BLOCKS used in narrow phase.
[out]	numDyFrictionBlocks	The minimal recommended value for eMEM_FRICTION_BLOCKS used in the solver.
[out]	numDyConstraintBlocks	The minimal recommended value for eMEM_CONSTRAINT_BLOCKS used in the solver.

static PX_PHYSX_CORE_API bool PxPS3Config::initialize	(	PxU32	simSpuCount,
		PxU32	querySpuCount = `0`
	)

static

Initialize the SDK's SPU usage.

By default the PhysX SDK will not use any SPU resources.

Use this method after the SDK has been created to enable SPU use, the counts provide an upper bound on the number of SPUs used for all SPU tasks.

The number of SPUs used per stage can be set on the scene after its creation with setSceneParamInt().

Parameters

[in] simSpuCount Number of SPUs to use simultaneously for simulation tasks.

Parameters

[in] querySpuCount Ignored. See the Migration Guide, section "SPU batch queries" for more details about how to use SPU batched queries.

static PX_PHYSX_CORE_API void PxPS3Config::setSceneParamInt	(	PxScene &	scene,
		PxPS3ConfigParam::Enum	param,
		PxU32	value
	)

static

Sets the value of a parameter for the given scene.

for eSPU parameters, value is the number of initialized SPUs to use in a phase. a value of 0 reverts the phase to PPU execution.

for eMEM parameters, value is the number of reserved 16kB memory blocks for SPU execution.

Parameters

[in]	scene	A pointer to the PxScene.
[in]	param	The parameter to set.
[in]	value	The value to set the parameter to.
