ID3DX10SkinInfo::AddBoneInfluences method

Enable an existing bone to influence a group of vertices and define how much influence the bone has on each vertex.

Syntax

HRESULT AddBoneInfluences(
  [in] UINT  BoneIndex,
  [in] UINT  InfluenceCount,
  [in] UINT  *pIndices,
  [in] float *pWeights
);

Parameters

BoneIndex [in]

Type: UINT

An index that specifies an existing bone. Must be between 0 and the value returned by ID3DX10SkinInfo::GetNumBones.

InfluenceCount [in]

Type: UINT

Number of vertices to add to the bone's influence.

pIndices [in]

Type: UINT*

Pointer to an array of vertex indices. Each member of this array has a corresponding member in pWeights, such that pIndices[i] corresponds to pWeights[i]. The corresponding value in pWeights[i] determines how much influence BoneIndex will have on the vertex indexed by pIndices[i]. The size of the pIndices array must be equal to or greater than InfluenceCount.

pWeights [in]

Type: float*

Pointer to an array of bone weights. Each member of this array has a corresponding member in pIndices, such that pWeights[i] corresponds to pIndices[i]. Each value in pWeights is between 0 and 1 and defines the amount of influence the bone has over each vertex. The size of pWeights must be equal to or greater than InfluenceCount.

Return value

Type: HRESULT

If the method succeeds, the return value is S_OK. If the method fails, the return value can be: E_INVALIDARG or E_OUTOFMEMORY.
