Publishing model data

SuperMap supports loading *.3ds and *.sgm models which are popular nowadays in a 3D scene. Either *.3ds or *.sgm data can be selected when a model is to be added. However, it is recommended to convert the *.3ds data format to *.sgm before adding the data in order to improve the efficiency of adding a model and the display effect. When converting the *.3ds format to the *.sgm format, the system filters and extracts the model framework of *.3ds, and resamples its tiled texture to create a series of images with different resolutions. The images are also indexed. When a model is being loaded, the system will automatically add proper textures for display based on its indexing mechanism.

In SuperMap iDesktop 11i(2023), the operation steps for converting *.3ds data to *.sgm data and publishing them are as follows:

1. Click the Model>Model conversion under the Data>3D Data tab. A Model->OSGB/S3M dialogue box will pop up. Set the path of the source 3DS model files (batch conversion is used here), and then set the path for saving the target SGM models after conversion (batch conversion is used here). Click the Convert button to implement the model conversion operation.

2. Create a new 3D scene;

3. Click the Add Model button under the Scenes tab. The Add Model dialogue box will pop up. Select a layer to save the model, or click the New Layer button to create a new layer for storing the model information. It is recommended to select 3D model cache file format (*.scv) as the layer type. Click the Add Model button. The Open 3D Model File dialogue box will pop up. Select the model file (the converted SGM file) to be added and click on Open. Click the OK button to complete the operation.

4. Save the 3D scene and the workspace;

5. Publish the workspace where the data are.
