Function Documentation

void NvFlowGridEmitCustomGetLayerParams	(	const NvFlowGridEmitCustomEmitParams *	emitParams,
		NvFlowUint	layerIdx,
		NvFlowGridEmitCustomEmitLayerParams *	emitLayerParams
	)

Get per layer custom emit parameters, should only be called inside the custom emit callback.

Parameters:

[in]	emitParams	The custom emit parameters.
[in]	layerIdx	The layerIdx to fetch, should be least than emitParams->numLayers.
[out]	emitLayerParams	Pointer to write parameters to.

void NvFlowGridEmitCustomRegisterAllocFunc	(	NvFlowGrid *	grid,
		NvFlowGridEmitCustomAllocFunc	func,
		void *	userdata
	)

Sets custom allocation callback.

Parameters:

[in]	grid	The grid to use the callback.
[in]	func	The callback function.
[in]	userdata	Pointer to provide to the callback function during execution.

void NvFlowGridEmitCustomRegisterEmitFunc	(	NvFlowGrid *	grid,
		NvFlowGridTextureChannel	channel,
		NvFlowGridEmitCustomEmitFunc	func,
		void *	userdata
	)

Sets custom emit callback for given simulation channel.

Parameters:

[in]	grid	The Flow grid to use the callback.
[in]	channel	The simulation channel for this callback.
[in]	func	The callback function.
[in]	userdata	Pointer to provide to the callback function during execution.
