NvFlowVolumeShadow* NvFlowCreateVolumeShadow	(	NvFlowContext *	context,
		const NvFlowVolumeShadowDesc *	desc
	)

Creates a volume shadow object.

Parameters:

[in]	context	The context for GPU resource allocation.
[in]	desc	Description for memory allocation.

Returns:

The created volume shadow object.

void NvFlowReleaseVolumeShadow

(

NvFlowVolumeShadow *

volumeShadow

)

Releases a volume shadow object.

Parameters:

[in]

volumeShadow

The volume shadow object to be released.

void NvFlowVolumeShadowDebugRender	(	NvFlowVolumeShadow *	volumeShadow,
		NvFlowContext *	context,
		const NvFlowVolumeShadowDebugRenderParams *	params
	)

Draw debug visualization of sparse volume shadow structure.

Parameters:

[in]	volumeShadow	The volume shadow object.
[in]	context	The context that created the volume shadow object.
[in]	params	Parameters for debug visualization.

NvFlowGridExport* NvFlowVolumeShadowGetGridExport	(	NvFlowVolumeShadow *	volumeShadow,
		NvFlowContext *	context
	)

Get grid export with shadow results. Currently, shadow results are placed in z component (the burn component).

Parameters:

[in]	volumeShadow	The volume shadow object.
[in]	context	The context that created the volume shadow object.

Returns:

Returns grid export with shadow results.

void NvFlowVolumeShadowGetStats	(	NvFlowVolumeShadow *	volumeShadow,
		NvFlowVolumeShadowStats *	stats
	)

Get stats for latest shadow computation.

Parameters:

[in]	volumeShadow	The volume shadow object.
[out]	stats	Destination for shadow computation stats.

void NvFlowVolumeShadowUpdate	(	NvFlowVolumeShadow *	volumeShadow,
		NvFlowContext *	context,
		NvFlowGridExport *	gridExport,
		const NvFlowVolumeShadowParams *	params
	)

Generate shadows from provided grid export.

Parameters:

[in]	volumeShadow	The volume shadow object.
[in]	context	The context that created the volume shadow object.
[in]	gridExport	The grid export to use for generating shadows.
[in]	params	Parameters for shadow generation.
