Proof Of Concept/Test for multilayer visualization

in experimental state

Running

suggested to use UV, https://github.com/astral-sh/uv

uv sync
uv run python main.py

Linux

uv sync
uv run python main.py

if no opengl backend or errors try this to debug (maybe try to get glxgears or vispy minimal example running first):

uv run python
import vispy
print(vispy.sys_info())

if not, you should try to install opengl drivers libs whatever, maybe test with smaller vispy example

OSX

uv sync
uv run python main.py

maybe uncomment quartz package in pyproject.toml for better performance

Windows

1. install uv
2. edit pyproject.toml and un-comment last line constraint-dependenc...
3. run:

uv sync
uv run python main.py

3d Visualization Tipps

Try different layout algorithms

• click in 3d place to activate keyboard shortcuts
• press z for a top view to easily see the aggregated view of layers
• select algorithm in dropdown at the loader panel at the top and press load button
• there are some custom algorithms starting with "cluster_" that primarily focus on keeping clusters together
• use slider in top loader panel to change z offset between layers

Mouse & Keyboard Interaction

• rotate: mouse drag
• panning: shift + mouse-drag
• zoom/change distance: scrollwheel or two finger drag on mac trackpad, or shift + right click

Click into 3D Viz to activate keyboard inputs.

• z view from top a long z axis
• x view along x axis
• y view along x axis
• r reset camera
• c center camera
• w and s, a and d, q and e, rotate slightly around axis

Aggregated Layer View

• click into 3d view to enable keyboard shortcuts
• press z

Inspect interlayer-edges of node

• disable Intralayer Edges in Display Options
• enable Show Node Labels
• click into 3d view to enable keyboard shortcuts
• press z
• press s one time
• zoom in very very close

now you should see vertical lines for each Interlayer Edge (arranged in circle around node for better distinguishing (no overlapping))

Quick Node based Layer statistics

• disable Intralayer Edges and Show Nodes
• enable Node Labels and Show Inter Stats Bars
• click in 3D view to enable keyboard shortcuts
• press z

now you should see in-place bar charts with

• number of active layer for node
• number of Interlayer edges (this corresponds to the numbers in the node label)
