您好，请问,在iDesktop 9d 9.1.0.14306( iobject.net : 9.1.0.16631) 桌面端，可以编辑模型更新纹理．但是在iobjects .net上，出现问题．
问题：１，以下代码的方式更改GeoModel3D的纹理，存在什么问题？
２，正确的更新GeoModel3D纹理的方法是什么？
问题环境：supermap-iobjectsdotnet-9.1.1-16828-70590-all.zip
应用６４位． 操作系统：win7 x64
数据为模型数据集．
图层类型：SuperMap.Realspace.Layer3DDataset
楼房模型：GeoModel3D
Model：存在纹理，且属性如下：
HasLOD false bool
LODCount 0x00000000 int
重现步骤：
１，让模型图层，可编辑．
２，用鼠标选中一个带纹理的模型时，运行测试代码A．
３，场景内模型建筑并没有更新为指定的纹理．
测试代码A 如下：
void UpdateTexture(GeoModel3D geoModel3D,int iLod)
{
try
{
string strModelLayer = "Building@OlympicGreen";
Scene scene = Scene;
Layer3D layer3D = scene.Layers[strModelLayer];
layer3D.IsEditable = true;
Model model = geoModel3D.Model;
int count = model.GetSkeletonCount(iLod);
for (int i = 0;i < count; i++)
{
SkeletonID id = new SkeletonID();
id.Skeleton = i;
id.LOD = iLod;
Skeleton skeleton = model.GetSkeleton(id);
if (null == skeleton)
{
continue;
}
Material3D material3D = skeleton.Material;
int iCountTexture = material3D.Textures.Count;
material3D.RemoveTextures();
List<TextureData> list = new List<TextureData>();
for (int j = 0; j < iCountTexture; j++)
{
TextureData textureData = new TextureData();
textureData.Name = "08oh0301.jpg";
string strPath = @"E:\08oh0301.jpg";
textureData.FromFile(strPath);
list.Add(textureData);
}
material3D = new Material3D();
material3D.Name = "materialName";
material3D.Textures = list;
if(list.Count > 0)
{
TextureData textureData = list[0];
material3D.Texture = textureData;
}
else
{
TextureData textureData = new TextureData();
textureData.Name = "08oh0301.jpg";
string strPath = @"E:\08oh0301.jpg";
textureData.FromFile(strPath);
material3D.Texture = textureData;
}
skeleton.Material = material3D;
model.Update(skeleton);
}
geoModel3D.Model = model;
layer3D.UpdateData();
}
catch(Exception e)
{
}
finally
{
Scene.Refresh();
}
}
