SkinningAttributeData (struct)¶
A simple struct that holds the data for the SkinningAttribute. This struct can be moved to the GPU wholesale, and its methods will also continue to work on the GPU. This is a workaround untill objects are supported on the GPU. currently only structs are supported, so we move the data and important fucntions to the struct, and add the struct to objct as a member.

Methods in detail¶
SkinningAttributeData ( in SkinningAttributeData other )
copy constructor
SkinningAttributeData SkinningAttributeData.clone? ()
clone method
SkinningAttributeData.cloneMembersTo? ( io SkinningAttributeData that )
SkinningAttributeData.copyFrom! ( in SkinningAttributeData other )
SkinningAttributeData.copyValue! ( in Size sourceIndex, in Size targetIndex )
SkinningAttributeData.copyValue! ( in SkinningAttributeData source, in Size sourceIndex, in Size targetIndex )
Boolean SkinningAttributeData.equalValues? ( in Size index1, in Size index2 )
Returns true if id-weight pair values are the same, considering it is an unordered set (it will return ‘true’ even if pair order differs, as long as values are the same).
SkinningAttributeData.getLinearCombination? ( in LocalL16UInt32Array sourceIndices, in LocalL16ScalarArray sourceWeights, out LocalL16UInt32Array skinIds, out LocalL16ScalarArray skinWeights )
Returns the ids and weights arrays (1 to 1 correspondence) resulting from the linear combination of source items (sourceWeights: factors per source, not the same as id-weight values)
| sourceIndices | The array of source indices |
| sourceWeights | The array of source weights, which need to correspond to each sourceIndices. Normally the sum of the weights should be 1.0 |
SkinningAttributeData.getPair? ( in UInt32 index, in UInt32 offset, out UInt16 id, out Scalar weight )
Returns for item ‘index’, returns the id-weight values for pair ‘offset’
UInt16 SkinningAttributeData.getPairCount? ( in UInt32 index )
Returns the number of id-weight pairs for a given item
SkinningAttributeData.getPairs? ( in UInt32 index, out LocalL16UInt32Array skinIds, out LocalL16ScalarArray skinWeights )
For an item, returns ids and weights arrays (1 to 1 correspondence)
SkinningAttributeData.linearCombine! ( in Ref<Object> sourceAttr, in LocalL16UInt32Array sourceIndices, in LocalL16ScalarArray sourceWeights, in Size targetIndex )
Size SkinningAttributeData.memUsage? ()
SkinningAttributeData.normalize! ( in Size index )
Normalizes the weights of the item so it sums to 1.0. If the sum is almost 0, will set equal weights.
SkinningAttributeData.resize! ( in Size count )
SkinningAttributeData.setPair! ( in UInt32 index, in UInt32 offset, in UInt16 id, in Scalar weight )
Returns for item ‘index’, sets the id-weight values for pair ‘offset’
SkinningAttributeData.setPairCount! ( in UInt32 index, in UInt16 pairCount )
Sets the number of id-weight pairs for the item (resizes item)
SkinningAttributeData.setPairs! ( in UInt32 index, in LocalL16UInt32Array skinIds, in LocalL16ScalarArray skinWeights )
For an item, set ids and weights arrays (1 to 1 correspondence)
Size SkinningAttributeData.size? ()
