Detailed Description

IRdVertexSkinStream:

• Specifies base vertex position
• Per vertex skin weights and skin matrices; Indices for skinning.
• The stream is part of IRdMesh and is stored in Vertex stream group.
• Stream is identified by STREAMID_VERTEXES_SKIN id.

Property Documentation

RtUlong* IRdVertexSkinStream::Matrix([in] RtDWORD dwIndex, [in] RtDWORD dwWeight) [get]

Get vertex skin matrix index.

• Each skin weight is stored as vertex index and vertex weight.
• Stream is used if number of weight painted vertices < 1/2 of all mesh vertices.
• Otherwise IRdSkinWeightDirect stream is used for saving memory.

Remarks:

In order to get at skin matrix index value, we need to use both the Vertex Index and Weight Index.

Parameters:

	dwIndex	[in] Vertex index in stream.
	dwWeightId	[in] Weight index in skin weight stream.

Returns:

pVal [out,retval] Returned vertex skin matrix index value.

standard HRESULT processing can be applied to returned value.

RtUlong IRdVertexSkinStream::Matrix([in] RtDWORD dwIndex, [in] RtDWORD dwWeight) [set]

Set vertex skin matrix index.

Parameters:

	dwIndex	[in] Vertex index in stream.
	dwWeightId	[in] Weight index in stream.
	newVal	[in] New skin matrix index value to set.

Returns:

standard HRESULT processing can be applied to returned value.

RtFloat* IRdVertexSkinStream::Weight([in] RtDWORD dwIndex, [in] RtDWORD dwWeight) [get]

Get vertex skin weight.

Parameters:

	dwIndex	[in] Vertex index.
	dwWeightId	[in] Weight index.

Returns:

pVal [out,retval] Returned weight value.

standard HRESULT processing can be applied to returned value.

RtFloat IRdVertexSkinStream::Weight([in] RtDWORD dwIndex, [in] RtDWORD dwWeight) [set]

Set vertex skin weight.

Parameters:

	dwIndex	[in] Vertex index.
	dwWeightId	[in] Weight index.
	newVal	[in] New weight value to set.

Returns:

standard HRESULT processing can be applied to returned value.

RtFloat* IRdVertexSkinStream::x([in] RtDWORD dwIndex) [get]

Get x-coordinate of i-th vertex.

Parameters:

dwIndex

[in] Vertex index.

Returns:

pVal [out,retval] Returned x-coordinate value.

standard HRESULT processing can be applied to returned value.

RtFloat IRdVertexSkinStream::x([in] RtDWORD dwIndex) [set]

Set x-coordinate of i-th vertex.

Parameters:

	dwIndex	[in] Vertex index.
	newVal	[in] New x-coordinate value to set.

Returns:

standard HRESULT processing can be applied to returned value.

RtFloat* IRdVertexSkinStream::y([in] RtDWORD dwIndex) [get]

Get y-coordinate of i-th vertex.

Parameters:

dwIndex

[in] Vertex index.

Returns:

pVal [out,retval] Returned y-coordinate value.

standard HRESULT processing can be applied to returned value.

RtFloat IRdVertexSkinStream::y([in] RtDWORD dwIndex) [set]

Set y-coordinate of i-th vertex.

Parameters:

	dwIndex	[in] Vertex index.
	newVal	[in] New y-coordinate value to set.

Returns:

standard HRESULT processing can be applied to returned value.

RtFloat* IRdVertexSkinStream::z([in] RtDWORD dwIndex) [get]

Get z-coordinate of i-th vertex.

Parameters:

dwIndex

[in] Vertex index.

Returns:

pVal [out,retval] Returned z-coordinate value.

standard HRESULT processing can be applied to returned value.

RtFloat IRdVertexSkinStream::z([in] RtDWORD dwIndex) [set]

Set z-coordinate of i-th vertex.

Parameters:

	dwIndex	[in] Vertex index.
	newVal	[in] New z-coordinate value to set.

Returns:

standard HRESULT processing can be applied to returned value.
