本文介绍了一种在A3D中批量转换ATF纹理的方法，并提供了Flex6图形界面转换器的代码示例。同时，详细讲解了如何在A3D源代码中使用这些转换后的ATF纹理。

经过对A3d的源代码的阅读后，一直搞不定的aft有了结果，特拿出分享，希望对大家有用。

首先呢要有atf图片这个是要经历两个转换过程首先在photoshop中转换成dds . 如果是多张需要做批处理脚本

然后制作动作

这个地方如果不清楚可以查阅ps的使用说明。

然后是使用dds2atf进行批量atf转换

核心的语句是在cmd 窗中有如下语法。

我采用的是比较高的压缩

举例代码
D:\dds2atf\dds2atf.exe -4 -q 180 -f 15 -i D:\dds2atf\ma01.dds -o D:\dds2atf\map01.atf'

atf的批量转换需要写一个图形界面转换器，这样比较方便。

在flex6中新建air工程，代码如下。

这样就能方便的完成atf的批量转换。

下面就是在a3d中使用atf了。喝口水继续。

首先是嵌入资源
[Embed ("map50.atf", mimeType = "application/octet-stream") ] private static const map50:Class;
建立ATFTextureResource
var  levelResourceatf:ATFTextureResource=new ATFTextureResource(new map50() as ByteArray);
修改a3d源代码
ATFTextureResource.as
57行

private function uploadInternal(context3D:Context3D, async:Boolean = false, callback:Function = null):void {
if (_texture != null) _texture.dispose();
if (data != null) {

data.position = 6;
trace(type);
var type:uint = data.readByte();
var format:String;
switch (type & 0x7F) {
   case 0:
   format = Context3DTextureFormat.BGRA;
   break;
   case 1:
   format = Context3DTextureFormat.BGRA;
   break;
   case 2:
   format = Context3DTextureFormat.COMPRESSED;
   break;
      case 3: /////主要是增加了这个分支
      format = Context3DTextureFormat.COMPRESSED;
   break;

}

调用代码为
var  levelResourceatf:ATFTextureResource=new ATFTextureResource(new map50() as ByteArray);
   levelResourceatf.upload(stage3D.context3D);

  var levelMaterial:TextureMaterial = new TextureMaterial(levelResourceatf);
然后使用这个levelMaterial 赋予物体。
level.setMaterialToAllSurfaces(levelMaterial);

atf可用。
