3--6D数据映射和Maya可视化 完整项目代码Data-Processing/FBX_SDK_Maya
1--Maya数据解析
在软件Maya中直接拖入FBX文件可以播放和查看人体各个骨骼关节点的数据 对于上图来说平移X、平移Y和平移Z表示关节点的Local Transaction的坐标而旋转X、旋转Y、旋转Z表示关节点的Euler Rotation坐标对于一个固定的人体模型修改每一帧中各个关节点的上述六个坐标即可改变人体表现的动作 在Maya中可以通过以下脚本在Python编辑器窗口→常规编辑器→脚本编辑器中打印所有帧所有关节的上述6D坐标数据 File : print_joint_6Ddata_maya.py

2--FBX SDK导出6D数据
通过Python FBX SDK我们可以提取和保存在一个原始FBX文件中对应于Maya可视化的6D坐标具体的脚本如下FBX_SDK_Maya/Extract_local_TR.py
3--6D数据映射和Maya可视化 通过第2步的脚本可以提取人体运动的关键6D坐标数据这些6D坐标数据可以进行一些动作生成任务生成相同意义的坐标数据。原始6D或生成的6D坐标数据可以使用以下脚本并在Maya中进行可视化 File : set_joint_6Ddata_maya.py
