virtual void nvidia::apex::ClothingAsset::getBoneMapping

(

uint32_t *

internal2externalMap

)

const [pure virtual]

returns the mapping from internal to external indices for a given asset.

Use this map to transform all the boneIndices returned from the ClothingPhysicalMesh into the order you specified initially

virtual void nvidia::apex::ClothingAsset::getMeshSkinningMap	(	uint32_t	lod,
		ClothingMeshSkinningMap *	map
	)		[pure virtual]

Provides the mesh to mesh skinning map.

This map stores for each graphics mesh vertex the corresponding triangle indices of the physics mesh and barycentric coordinates to skin the vertex position, normal and tangent.

Note:

This call has the side effect of merging the immediate map into the mesh skinning map. This might affect skinning performance done by APEX.

Parameters:

[in]	lod	lod for which the map is requested
[out]	map	Skinning map

virtual uint32_t nvidia::apex::ClothingAsset::getMeshSkinningMapSize

(

uint32_t

lod

)

[pure virtual]

Returns the size of the mesh skinning map.

Note:

This call has the side effect of merging the immediate map into the mesh skinning map. This might affect skinning performance done by APEX.

Returns:

Number of entries in the map

virtual const RenderMeshAsset* nvidia::apex::ClothingAsset::getRenderMeshAsset

(

uint32_t

lodLevel

)

const [pure virtual]

Gets the RenderMeshAsset associated with this asset.

Parameters:

[in]

lodLevel

The LoD level of the render mesh asset

Returns:

NULL if lodLevel is not valid

ClothingAsset::getNumGraphicalLodLevels()

virtual uint32_t nvidia::apex::ClothingAsset::prepareMorphTargetMapping	(	const PxVec3 *	originalPositions,
		uint32_t	numPositions,
		float	epsilon
	)		[pure virtual]

Prepares the asset for use with morph target.

When setting morph target displacements, the asset needs to create a mapping of external to internal vertex order. These positions will be matched with the internal mesh positions with a smallest distance criterion.

Parameters:

[in]	originalPositions	Array of positions before the morphing is applied.
[in]	numPositions	Length of the Array
[in]	epsilon	Difference two vertices can have before being reported

Returns:

Number of vertices for which the distance to the next originalPosition was larger than epsilon

virtual bool nvidia::apex::ClothingAsset::remapBoneIndex	(	const char *	name,
		uint32_t	newIndex
	)		[pure virtual]

remaps bone with given name to a new index for updateState calls

This is needed when the order of bones differs from authoring tool to runtime

Note:

must be called after asset is deserialized. Changing this any later, especially after the first ClothingActor::updateState call will lead to ill-defined behavior.
