Viewing scenes

Selet Resource Center->Scenes from the navigation bar of the SuperMap iPortal home page to enter the scenes list page. Click the scene thumbnail to enter the SceneViwer page, which supports the scene layer control, panning, zooming, tilting and rotation and other operations.

SuperMap iPortal supports SuperMap iClient3D for WebGL (referred to as WebGL client), you can browse the 3D scene in the Earth without installing the plug-in.

The supported 3D scene format for browsing is as follows:

The supported vector and model cache formats: 3m and osgb. We recommend using s3m format scenes, because the transimission and loading are faster than other formats.
Image data supports the caches generated through global partitioning.
Terrain data supports Tin terrain.

Note：

For SuperMap iDesktop 8C(2017) SP1 or higher verion, terrian and image data support WebGL client by default; the supported format for vector caches and model caches is osgb.
About verifying that your browser and installation machines support scenarios See: Earth configuration requirements.

The scene basic information

Click "Scene" on the iPortal Portal to enter the Scene List page and click on the thumbnail of the scene to enter the Earth page. The left side of the page shows the basic information of the scene, including the creator of the scene, the creation time, the sharing Information, label and three-dimensional service address, click on the three-dimensional service address can view the scene corresponding to the three-dimensional service information.

Layer control

In a three-dimensional scene, the data is loaded onto a three-dimensional sphere and, like a two-dimensional map, is loaded onto the ball in layers. For example: image data, terrain data, vector data, are displayed by loading into different layers. In a three-dimensional scenario, the layers can be divided into four types: normal layer, trace layer, screen layer, and terrain layer, depending on the contents of the loaded data.

3D scenes can contain multiple common three-dimensional layers (Layer3D), can also contain multiple terrain layer (TerrainLayer). In the Earth, click the Layers tab. You can view all the layers contained in the currently open scene. You can set the visibility of the layer by checking the check box before the layer.

Scene operation

The following table lists the relationship between the interaction and the mouse and keyboard. The roaming operation includes translation, zoom, tilt and rotation of the four operations, corresponding to the navigation bar on the different button function.

Browsing function	Mouse operation	Keyboard operation	Navigation tool bar
Pan	Drag the left mouse button up and down	Up and down cursor key
Zoom	The middle mouse button or the right mouse button to drag up and down	PageUp and PageDown keys
The three-dimensional map scene is tilted	Hold down the middle mouse button to drag up and down	Shift + up and down cursor keys
Rotate around the center of the scene	Hold down the middle mouse button to drag left and right	Shift + left and right cursor keys
