[求助]请教SceneControl里图层设基高
private void setbaseheight()<BR> {<BR> ISceneGraph scenegraph = axSceneControl1.SceneGraph;<BR> <BR> IScene scene = scenegraph.Scene;<BR> ILayer layer;<BR> int j;<BR> for (j = 0; j < scene.LayerCount - 1; j++)<BR> {
<P> layer = scene.get_Layer(j);</P> <P> IRasterLayer rlayer;<BR> rlayer = layer as IRasterLayer;<BR> IRaster raster;<BR> IRasterSurface rsurface = new RasterSurface();</P> <P> raster = (IRaster)rlayer.Raster;<BR> ISurface surface;<BR> IRasterBandCollection rasterbands = raster as IRasterBandCollection;<BR> IRasterBand rasterband = rasterbands.Item(1);<BR> rsurface.RasterBand = rasterband;<BR> surface = rsurface as ISurface;</P> <P> ILayerExtensions layerextensions = rlayer as ILayerExtensions;<BR> I3DProperties properties = new Raster3DPropertiesClass();<BR> int i;<BR> for (i = 0; i < layerextensions.ExtensionCount - 1; i++)<BR> { <BR> <BR> if ( layerextensions.get_Extension(i)!=null)<BR> {<BR> properties = (I3DProperties)layerextensions.get_Extension(i); <BR> <BR> }<BR> }<BR> properties.BaseOption = esriBaseOption.esriBaseSurface;<BR> properties.BaseSurface = surface;<BR> </P> <P> properties.Apply3DProperties(layer);<BR> scenegraph = scene.SceneGraph;</P> <P> scenegraph.RefreshViewers();<BR> }<BR> <BR> <BR> }</P> <P>请问里面哪里写错了？我运行的时候没有结果，图层还是原来平平的样子。谢谢</P> |
