您好,可以参考:
GeoStyle3D geoStyle3D = new GeoStyle3D();
geoStyle3D.setAltitudeMode(com.supermap.data.AltitudeMode.ABSOLUTE);
geoStyle3D.setLineWidth(3);
geoStyle3D.setLineColor(Color.YELLOW);
layer3DSettingVector.setStyle (geoStyle3D);
//将矢量数据集显示在三维场景中
Layer3DDataset layer3DDataset=sceneObject.getLayers().add(tempDatasetVector, layer3DSettingVector, true);
layer3DDataset.updateData();
sceneObject.refresh();
