Accessing TGView3D

There are two ways of starting TGView3D:

With a browser: https://tgview3d.mathhub.info
With the desktop application, see releases

Loading Graphs

To access graphs, you can browse MathHub or load it directly with TGView3D. You can:

Extend the URL with a link to a JSON graph file like this: https://tgview3d.mathhub.info/?https://kwarc.info/teaching/IWGS/graph.json
Enter an absolute URL into the UI field or select localhost to get localhost:8080 or mathhub for https://mmt.mathhub.info/ as prefix.
Select a local JSON file.
Choose an example graph from the example list.

Working with Graphs

Navigation

Move Graph: Hold Middle MB
Rotate Graph: Hold RMB
Select Node: LMB

Customization

Hide edge types by deselecting the box left to the node types
Change the layout handling of edge types by selecting another option below the respective node type.
Click on the 'Layout' Button again to perform further layouting steps (this way you can also relayout the graph after changing the properties above)
Switch between 2D/3D and black/white background by selecting the checkboxes at the top

Exploration

Hide distant edges to focus on nearer parts of the graph: Deselect 'Show Full Graph'
Crawl through the graph by selecting nodes and their direct neighbors: Deselect 'Show All Edges'
Show successor/predecessor subgraph of node: Select node and click on 'Node Bicone' Button (clicking on the button with same node selection again disables the bicone)
Change node spacing with the 'Scale Graph' Slider in the UI
