ID3DX10SkinInfo interface
ID3DX10SkinInfo allows you to optimize, process, and manually set the relationship between bones and vertices in your meshes (see Skeletal Animation on Wikipedia). It is most useful for making .x files exported by DCC Apps (such as 3DS Max and Maya) more hardware-friendly, and for improving the render speed of your skinned meshes in software render mode.
Members
The ID3DX10SkinInfo interface inherits from the IUnknown interface. ID3DX10SkinInfo also has these types of members:
Methods
The ID3DX10SkinInfo interface has these methods.
| Method | Description |
|---|---|
| AddBoneInfluences | Enable an existing bone to influence a group of vertices and define how much influence the bone has on each vertex. |
| AddBones | Allocate space for more bones. |
| AddVertices | Allocate space for additional vertices. |
| ClearBoneInfluences | Clear a bone's list of vertices that it influences. |
| Compact | Limit the number of bones that can influence a vertex and/or limit the amount of influence a bone can have on a vertex. |
| DoSoftwareSkinning | Do software skinning on an array of vertices. |
| FindBoneInfluenceIndex | Find the index that indicates where a given vertex is in a given bone's list of influenced vertices. |
| GetBoneInfluence | Get the amount of influence a given bone has over a given vertex. |
| GetBoneInfluenceCount | Get the number of vertices that a given bone influences. |
| GetBoneInfluences | Get a list of vertices that a given bone influences and a list of the amount of influence that bone has on each vertex. |
| GetMaxBoneInfluences | Get the number of vertices a bone can maximally influence. |
| GetNumBones | Get the number of bones in ID3DX10SkinInfo. |
| GetNumVertices | Get the number of vertices in ID3DX10SkinInfo. |
| RemapBones | Change which bones influence which vertices. |
| RemapVertices | Change which vertices are influenced by which bones. |
| RemoveBone | Remove a bone. |
| SetBoneInfluence | Set the amount of influence a given bone has over a given vertex. |
Remarks
Create a ID3DX10SkinInfo interface with D3DX10CreateSkinInfo, D3DX10CreateSkinInfoFromBlendedMesh, or D3DX10CreateSkinInfoFVF.
The LPD3DX10SKININFO type is defined as a pointer to the ID3DX10SkinInfo interface.
typedef struct ID3DX10SkinInfo *LPD3DX10SKININFO;
