3dsmax导出游戏模型.x文件插件[原转]

用3dsmax建好模之后,并不能直接在directx3d中使用,我们要使用.x文件,而3dsmax又不自带这种导出功能,
 我们只有求助于插件的帮助了.
 这里介绍两个插件,还没有去试,晚上试着看一下,先说则个.
 第一个是:Xporter v1.11
 Xporter是一个用于在3ds max中导出\导入X-File的插件,同时也能够导出带动画的网格物体,目前只支持3ds max 6 和 7.

 第二个是panda export,也是我们着重介绍的.这个插件更新非常快,目前当3dsmax版本为8的时候,他已经也
 有相应的版本了.强力推荐.

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

PDE和微软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 ??

导出.x文件后可以用dxsdk附带的mesh viewer观看，不过我试了一个文件，dx9的mesh viewer居然不能打开。推荐一个软件3d explorer,不但可以观看各种模型格式，还可以显示.x文件的层次信息和里面的数据，不过这个软件用的是右手坐标系。3d explorer似乎就是deep explorer的前生。
