Enumeration Type Documentation

Emitter modes.

Enumerator:

eNvFlowGridEmitModeDefault	Emitter will influence velocity and density channels, optionally allocate based on bounds.
eNvFlowGridEmitModeDisableVelocity	Flag to disable emitter interaction with velocity field.
eNvFlowGridEmitModeDisableDensity	Flag to disable emitter interaction with density field.
eNvFlowGridEmitModeDisableAlloc	Flag to disable emitter bound allocation.
eNvFlowGridEmitModeAllocShape	Emitter will allocate using shape to drive allocation instead of only bounds.
eNvFlowGridEmitModeAllocShapeOnly	Flags to configure for shape aware allocation only.

void NvFlowGridEmit	(	NvFlowGrid *	grid,
		const NvFlowShapeDesc *	shapes,
		NvFlowUint	numShapes,
		const NvFlowGridEmitParams *	params,
		NvFlowUint	numParams
	)

Adds one or more emit events to be applied with the next grid update.

Parameters:

`[in]`	grid	The Flow grid to apply the emit events.
`[in]`	shapes	Array of shape data referenced by emit params.
`[in]`	numShapes	Number of shapes in the array.
`[in]`	params	Array of emit event parameters.
`[in]`	numParams	Number of emit events in the array.

void NvFlowGridEmitParamsDefaults ( NvFlowGridEmitParams * params )

Allows the application to request default emit parameters from Flow.

Parameters:

[out] params The parameters for Flow to fill out.

void NvFlowGridUpdateEmitMaterials	(	NvFlowGrid *	grid,
		NvFlowGridMaterialHandle *	materials,
		NvFlowUint	numMaterials
	)

Update internal array of grid materials reference by emitMaterialIndex

Parameters:

`[in]`	grid	The Flow grid to apply the emit events.
`[in]`	materials	Array of grid materials.
`[in]`	numMaterials	Number of grid materials in the array.

void NvFlowGridUpdateEmitSDFs	(	NvFlowGrid *	grid,
		NvFlowShapeSDF **	sdfs,
		NvFlowUint	numSdfs
	)

Update internal array of SDFs that can be referenced by sdfOffset

Parameters:

`[in]`	grid	The Flow grid to apply the emit events.
`[in]`	sdfs	Array of shape data referenced by emit params.
`[in]`	numSdfs	Number of shapes in the array.
