Load Tiles

Usage

SuperMap iDesktopX provides the Load Tiles function, mainly including:

  • Load Tiles: Add existing tile data to a scene in the scene window, including: image tile files (*.sci3d, *.sci), 3D terrain tile files (*.sct), 3D vector tile files (*.scv), 3D tile files (*.scp), global map tile files (*.sci), and Cesium 3DTiles (*.json).
  • Load All Tiles in Folder: Batch add existing tile data to a scene in the scene window.

Since 11i (2022) SP1, spherical scenes use an ellipsoid basis by default. Directly loading S3M 1.0/2.0 data based on a sphere will perform dynamic projection conversion, reducing loading performance; if the data is a point plug-in model, it will also cause position errors. It is recommended to upgrade the data to S3M 3.0/3.01.

Currently, SuperMap iDesktopX only supports loading 3D Tiles 1.0/1.1 generated based on oblique photography 3D models, point clouds, normal material fine models, normal material BIM, and white models.

Function Entry

  • Scene tab > Data group -> Tiles
  • Layer Manager -> Normal Layer Collection Node Context Menu -> Add Image Tile Layer/Add 3D Tile Layer/Add Vector Slice Layer/Add Map Tile Layer
  • Layer Manager -> Terrain Layer Collection Node Context Menu -> Add Terrain Tiles

Operation Steps

Add Tiles

  1. After creating or opening a scene window, open the Add Tiles dialog box through the following operations:
    • Click the button part of the Tiles item in the Scene tab > Data group;
    • Click the drop-down button part of the Tiles item in the Scene tab > Data group, and select the Load Tiles... item in the pop-up drop-down menu;
    • Right-click the Normal Layer node in the Layer Manager, and select Add Image Tile Layer/Add 3D Tile Layer/Add Vector Slice Layer/Add Map Tile Layer in the pop-up context menu.
    • Right-click the Terrain Layer node in the Layer Manager, and select Add Terrain Tiles in the pop-up context menu. Currently, opening multiple DEM terrain tile data or only one TIN terrain tile data in a scene is supported. When loading multiple DEM terrain tile data and the tile spatial ranges overlap, it is recommended to keep the starting level number of each tile data with overlapping spatial ranges consistent.
  2. In the pop-up "Open Layer File" dialog box, select the configuration file of the 3D tile file to be loaded, and then click the "Open" button in the dialog box to complete the loading of 3D tile data.
    • When loading SuperMap image tiles, select the corresponding *.sci and *.sci3d configuration files.
    • When loading SuperMap 3D terrain tile files, select the corresponding *.sct configuration file.
    • When loading SuperMap 3D vector tile files, select the corresponding *.scv and *.scp configuration files.
    • When loading SuperMap global map tile files, select the corresponding *.sci configuration file.
    • When loading SuperMap S3M tile files, select the corresponding *.scp configuration file.
    • When loading SuperMap instance layer files, select the corresponding *.instc file.

    • When loading Cesium 3D Tiles data, select the corresponding *.json configuration file. Support is as follows:

      • Supported: 3D Tiles 1.0/1.1 generated from oblique photography 3D models, point clouds, normal material fine models, normal material BIM, white models, etc.

      • Not supported: 3D Tiles 1.0/1.1 whose source data is instance models, pipeline data, 3DGS, PBR material BIM, PBR fine models. 3D Tiles data published as a 3D service cannot be loaded.

      • Format restrictions: Only pnts and b3dm in 3D Tiles 1.0 are supported. cmpt and i3dm (such as instance models) are not supported.

  3. The newly loaded 3D tile data is displayed as a 3D layer in the scene on the simulated earth. For 3D terrain tiles, a 3D terrain layer node will be added under the "Terrain Layer" node in the Layer Manager, corresponding to the 3D terrain tile data layer just loaded; for other 3D tiles, a 3D tile layer node will be added under the "Normal Layer" node in the Layer Manager, corresponding to the 3D tile data layer just loaded.

    Double-click the left mouse button on the above two types of nodes, and the 3D globe will roam to the data range corresponding to the layer and zoom for display.

Batch Add Tiles

  1. After creating or opening a scene window, click the drop-down button part of the Tiles item in the Scene tab > Data group, and select the Load All Tiles in Folder... item in the pop-up drop-down menu.
  2. The "Browse For Folder" dialog box pops up. Specify the folder where the 3D tiles are located in the dialog box. Click the "OK" button to add all 3D tile files under the selected folder to the current scene.
  3. The newly loaded 3D tile data is displayed as a 3D layer in the scene on the simulated earth. For 3D terrain tiles, corresponding 3D terrain layer nodes are added under the "Terrain Layer" node in the Layer Manager; for other 3D tiles, corresponding 3D tile layer nodes are added under the "Normal Layer" node in the Layer Manager.

    Double-click the left mouse button on the above two types of nodes, and the 3D globe will roam to the data range corresponding to the layer and zoom for display.

Load Tiles Through Nested SCP

  1. After creating or opening a scene window, open the Add Tiles dialog box through the following operations:
    • Click the button part of the Tiles item in the Scene tab > Data group;
    • Click the drop-down button part of the Tiles item in the Scene tab > Data group, and select the Load Tiles... item in the pop-up drop-down menu;
    • Right-click the Normal Layer node in the Layer Manager, and select Add 3D Tile Layer in the pop-up context menu.
  2. In the pop-up "Open Layer File" dialog box, select the nested SCP (*.scp), and then click the "Open" button in the dialog box to complete the loading of 3D tile data. Nested SCP can be generated through Toolbox -> 3D Data -> Tile Tools -> Generate Nested SCP tool.
  3. 3D tiles loaded through nested SCP will be displayed as a layer group under the Normal Layer node in the Layer Manager.
    • The parent layer node corresponds to the nested SCP.
    • Child layers correspond respectively to the child SCPs recorded in the comprehensive nested SCP file.
    • The parent layer node context menu provides options such as Visible, Selectable, Zoom to This Layer, Quick Locate to This Layer, Open Containing Folder, and Remove.
    • The child layer node context menu is consistent with the normal 3D tile layer context menu. For specific operations, see Layer Context Menu.
    • Child layers can exchange order and set styles within the layer group, but cannot be moved out of the layer group or deleted. Layers can only be removed by removing the parent layer.
