3dMax匯出.x檔案以及3D Explorer

panda export是從3Dmax中匯出.x檔案的外掛程式
網站為：

最新版本：2005－11－27 v4.8.61.0 for 3ds Max8, v4.6.61.0 for 3ds Max6/7

PDE和微軟Export的不同：
1 PDE also changes the right-handed axis system that Max uses to a left-handed system more commonly used by directX. To do this the vertices have their z and y swapped around and the face is re-ordered (winding order).  Any other output is also changed such as matrices in the frames and animation sets. The MS version doesn't do this and expects either another pre-processing stage on the file or for the application program to alter its viewing matrices
2 Mesh vertices and normals are optimized to remove duplicates where possible.  If a vertex has a different normal value or texture coordinate whilst being shared by two faces then it can't be removed.  Choosing to turn off normals/texture coordinates and vertex colours will reduce the vertices count. 
3 Vertex Colours are supported, however, these need to be set in Max first.  The MS exporter doesn't support this at time of writing.
4 Any bitmap image used as a diffuse map material in Max can be converted to a .bmp file so that a quick check on the texture coordinates can be made. Native texture map .DDS support could be added ?? Well maybe there is a Max plugin for that ??

匯出.x檔案後可以用dxsdk附帶的mesh viewer觀看，不過我試了一個檔案，dx9的mesh viewer居然不能開啟。推薦一個軟體3d explorer,不但可以觀看各種模型格式，還可以顯示.x檔案的層次資訊和裡面的資料，不過這個軟體用的是右手座標系。3d explorer似乎就是deep explorer的前生。
