【Direct3D游戏开发】——蒙皮骨骼动画学习笔记

蒙皮骨骼动画

        一、蒙皮骨骼动画原理：蒙皮骨骼动画的思想来源于自然界，大多数动物都拥有一套骨骼，骨骼是身体的框架，身体的皮毛血肉都是依附于骨骼。当骨骼开始运动的时候，依附于对应骨骼的皮毛血肉都会随骨骼一起运动。而Mesh模型是由大量的三角形组成，三角形由定点组成。当我们运动时，有必要知道那些定点依附于那块骨骼，根据骨骼的移动来移动对应的顶点。

            蒙皮骨骼动画的加载：和Mesh模型的加载一样，骨骼加载时也是基于本地空间，我们需要把骨骼一块一块的从基于本地空间转换到整个Mesh模型空间。对于一套骨骼，有一个根（root）骨骼，这个根骨骼位于模型的一个定点，如坐标原点，其他骨骼都是直接或者间接与之联系。每根骨骼都有相对于其父母骨骼的相对位置（包括位移，和绕关节进行的转动），这种转换由一个矩阵完成：LocalTransformMatrix，这只是完成了骨骼的定位，要实现动画还需要对骨骼进行各种变换，如你所料，这肯定也是利用矩阵完成：CombinedTransformMatrix。当上层骨骼运动时，下层骨骼并不会主动运动，而是被牵连着运动，所以上层的运动会传递到下层骨骼，这个原理表示为：（子骨骼）CombinedTransformMatrix = （子骨骼）LocalTransformMatrix * （父母骨骼的）CombinedTransformMatrix.当然这中传递是渲染之前计算好的。

            关键结构体：Direct3d中一套骨骼是以树形结构存放的，有两个关键的结构体和一个接口。

                    1：typedef struct _D3DXFRAME

                            {

                                LPSTR                   Name;

                                D3DXMATRIX              TransformationMatrix;

                                LPD3DXMESHCONTAINER     pMeshContainer;

                                struct _D3DXFRAME       *pFrameSibling;

                                struct _D3DXFRAME       *pFrameFirstChild;

                            } D3DXFRAME, *LPD3DXFRAME;

                        这个结构体代表了一块骨骼，有一个标识的Name,变换矩阵TransformationMatrix对应于之前所说的LocalTransformMatrix,还有分别指向兄弟结点和第一个孩子结点的指针，最后是包含了一个指向D3DXMESHCONTAINER结构体的指针，这是第二个关键的结构体。

                    2：typedef struct _D3DXMESHCONTAINER

                            {

                                LPSTR                   Name;

                                D3DXMESHDATA            MeshData;

                                LPD3DXMATERIAL          pMaterials;

                                LPD3DXEFFECTINSTANCE    pEffects;

                                DWORD                   NumMaterials;

                                DWORD                  *pAdjacency;

                                LPD3DXSKININFO          pSkinInfo;

                                struct _D3DXMESHCONTAINER *pNextMeshContainer;

                            } D3DXMESHCONTAINER, *LPD3DXMESHCONTAINER;

                    对于这个结构体还是比较了解的，所以略。

                    3：ID3DXAllocateHierarchy 接口，这个接口只包含四个纯虚函数，我们需要去重写他们，这些函数无需我们自己调用，在我们使用D3DXLoadMeshHierarchyFromX()接口加载SkineMesh数据是自动调用。

                    4：D3DXLoadMeshHierarchyFromX  (

    LPCWSTR Filename,

    DWORD MeshOptions,

    LPDIRECT3DDEVICE9 pD3DDevice,

    LPD3DXALLOCATEHIERARCHY pAlloc,

    LPD3DXLOADUSERDATA pUserDataLoader, 

    LPD3DXFRAME *ppFrameHierarchy,

    LPD3DXANIMATIONCONTROLLER   *ppAnimController

    );

有几个关键的参数：pAlloc,这是一个指向3中所说的

ID3DXAllocateHierarchy 接口的指针；ppFrameHierarchy，骨骼层次，也就是一个代表骨骼的树，是一个返回值；ppAnimController，这是动画控制器，是一个返回值，利用这个动画控制器就可以对SkinMesh进行控制。

     蒙皮骨骼动画的渲染：渲染这部分比较简单，递归渲染每个MeshContainer，这样说可能很奇怪，因为每个骨骼结构体（D3DXFRAME）都包含了一个指向MeshContainer的指针，而每次渲染每个MeshContainer都是整副骨骼进行设置纹理和材质，然后就有问题了？这不是重复渲染了？百度，google和经自己调试发现，网上并没有找到标准答案，就是大多时候一个骨骼的MeshContainer指针都是空的，我在调试时候只有骨骼Name为空字符串时MeshContainer不为空，所以只渲染了一次，哦，我的模型是tiny.x。最后我估计：一套骨骼中也许只有一个或几个不为空的MeshContainer指针，通常是一个如果没必要分割渲染的话，递归只是为了寻找这个不为空的pMeshContainer.

笔记到此先告一段落，由于理解只在十分基本的层面，没法就很多细节进行分析，故在此只记录十分表面的东西，以后补足。PS:笔记主要参考《Direct3D游戏开发技术详解》，MSDN

参考：Direct3D游戏开发技术详解 和 SDK simple 简单的加载了tiny.x动画，只实现了SOFTWARE处理方式和走路的动画。
