场景中怎样设置标签专题图中标签相对于地面的高度

Answer 1

您好，标签专题图图层类型也是Layer3DDataset，所以也是在Layer3DDataset.AdditionalSetting 属性中设置它的风格

没弄明白，Theme3DLabel的样式设置和Layer3DDataset.AdditionalSetting之间的关系

---

Theme3DLabel的样式是设置文本的样式，比如文字大小，颜色，是否加粗等

---

还是要问一下具体在这个功能上怎样使用Layer3DDataset，帮助文档没看明白

---

首先获取到标签专题图

Layer3DDataset layerlable=Scene.Layers["标签专题图"] as Layer3DDataset;

设置图层的风格Layer3DDataset.AdditionalSetting

设置标签文本的风格 Theme3DLabel lable=Layer3DDataset.Theme as Theme3DLabel

要实现标注相对地面高度为10m,这样写有什么问题

Layer3DSettingVector layer3DSetting=new Layer3DSettingVector();

layer3DSetting = (this.m_LabelLayer_Animal_3D as Layer3DDataset).AdditionalSetting as Layer3DSettingVector;
GeoStyle3D geoStyle3D = new GeoStyle3D();
 geoStyle3D.AltitudeMode = AltitudeMode.RelativeToGround;
 geoStyle3D.ExtendedHeight = 10;
 layer3DSetting.Style = geoStyle3D;

有问题，应该设置GeoStyle3D.BottomAltitude 属性，而不是拉伸高度

嗯，发现了，实在不好意思，犯了个这种错误，你的这个回复现在才看到。
