Actionscript 3 将带有多个纹理的*.dae文件导入papervision 3D

通常，当您以*.dae格式导出3D对象时，文件附带一个文件夹，该文件夹包含对象的纹理，有人知道如何将*.dae文件及其纹理添加到我们的项目中吗？

您应该将纹理放置到*.dae文件夹中，并按如下方式加载对象和纹理：

    var bm:BitmapFileMaterial = new BitmapFileMaterial('PATH_TO_TEXTURE', true);
    var mat:MaterialsList = new MaterialsList();
    mat.addMaterial(bm2, 'MATERIAL_NAME');
    mat.addMaterial(bm3, 'ANOTHER_MATERIAL_NAME');

    var obj:DAE = new DAE();
    obj.useOwnContainer = true;
    obj.load('PATH_TO_DAE', mat);

    ...
      <library_images>
        <image id="TEXTURE_NAME-image" name="TEXTURE_NAME">
          <init_from>2/TEXTURE_NAME.png</init_from>
        </image>
      </library_images>
      <library_materials>
        <material id="TEXTURE_NAME" name="TEXTURE_NAME">
          <instance_effect url="#TEXTURE_NAME-fx"/>
        </material>
      </library_materials>
    ...
      <library_visual_scenes>
        <visual_scene id="RootNode" name="RootNode">
          <node id="TEXTURE_NAME_tp3_Mesh01" name="TEXTURE_NAME_tp3_Mesh01">
            <matrix sid="matrix">1.000000 0.000000 0.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 -1.000000 0.000000 0.000000 0.000000 0.000000 0.000000 1.000000</matrix>
            <instance_geometry url="#TEXTURE_NAME_tp3_Mesh01-lib">
              <bind_material>
                <technique_common>
                  <instance_material symbol="MATERIAL_NAME" target="#MATERIAL_NAME"/>
                </technique_common>
              </bind_material>
            </instance_geometry>
          </node>
        </visual_scene>
     </library_visual_scenes>

此外，应在*.dae中正确链接材质。大概是这样的：

    var bm:BitmapFileMaterial = new BitmapFileMaterial('PATH_TO_TEXTURE', true);
    var mat:MaterialsList = new MaterialsList();
    mat.addMaterial(bm2, 'MATERIAL_NAME');
    mat.addMaterial(bm3, 'ANOTHER_MATERIAL_NAME');

    var obj:DAE = new DAE();
    obj.useOwnContainer = true;
    obj.load('PATH_TO_DAE', mat);

    ...
      <library_images>
        <image id="TEXTURE_NAME-image" name="TEXTURE_NAME">
          <init_from>2/TEXTURE_NAME.png</init_from>
        </image>
      </library_images>
      <library_materials>
        <material id="TEXTURE_NAME" name="TEXTURE_NAME">
          <instance_effect url="#TEXTURE_NAME-fx"/>
        </material>
      </library_materials>
    ...
      <library_visual_scenes>
        <visual_scene id="RootNode" name="RootNode">
          <node id="TEXTURE_NAME_tp3_Mesh01" name="TEXTURE_NAME_tp3_Mesh01">
            <matrix sid="matrix">1.000000 0.000000 0.000000 0.000000 0.000000 0.000000 1.000000 0.000000 0.000000 -1.000000 0.000000 0.000000 0.000000 0.000000 0.000000 1.000000</matrix>
            <instance_geometry url="#TEXTURE_NAME_tp3_Mesh01-lib">
              <bind_material>
                <technique_common>
                  <instance_material symbol="MATERIAL_NAME" target="#MATERIAL_NAME"/>
                </technique_common>
              </bind_material>
            </instance_geometry>
          </node>
        </visual_scene>
     </library_visual_scenes>
