3D Renderer (In Beta)

This is a plugin for Cytoscape 3 that attempts to render networks in 3D and integrate itself with VizMapper. Currently, it is still under development.

Current Features (as of v0.55)

• (New) Preview and editing of visual styles through the VizMapper Panel

• Node and edge manipulation (node dragging, selection, addition, removal)
• Camera movement and rotation
• Bird's eye view that can navigate the main camera
• Basic node shapes (spheres, cubes, tetrahedrons)
• Basic edge line types (dashes, dots, solid)
• Basic visual properties (node fill color, edge fill color)
• Node label text rendering (in progress)

First-person camera turning:

Network Manipulation Controls

Node, edge addition and removal:

Selection:

• Drag the mouse to select objects, or click on nodes to select them.
• Hold SHIFT to add additional objects to the current selection.

Node dragging: Hold CTRL and drag the mouse to move currently selected nodes.

Bird's eye view

Under the Network tab to the left, click or drag the mouse on the bird's eye view display to move the main camera

Notes about Visual Properties

For node shapes, the following settings in VizMapper will give the following results:

(New as of v0.52) For edge line types, the following settings give the following results:

Currently Supported Visual Properties

Nodes:

• Node fill color
• Node shape
• Node dimensions: width, height, depth (as of v0.55)

Edges:

• Edge fill color
• Edge line type (new in v0.52)

Network:

• Network background color (as of v0.55)

Planned Features

• More complete set of supported visual properties

• Integration with VizMapper's default style previewer/editor

Source Code

The source code for the 3D renderer plugin may be found at the following SVN repository: http://chianti.ucsd.edu/svn/csplugins/trunk/toronto/yuedong/paperwing-impl

Known Issues

• Currently may crash if switching between networks when more than one network is opened at the same time.
• May crash if a network viewing window is resized such that the width:height ratio becomes less than 1.

• Node labels may not edit properly when attempting to change them through VizMapper.

• Node labels do not always directly face the camera.
• For networks that contain many nodes, there may appear to be edges with unlimited length. This is likely caused by errors in the calculation of edge coordinates for curved edges. (Bug mentioned by Keiichiro Ono)
