= Chimera 2 cellPACK Features =

Existing cellPACK user interface is through Cinema4d, Maya, Blender, or uPy.  Installation is difficult and most front-ends are expensive commercial products. Has dialogs for simple and advanced users.  Very big button farm dialogs.

Russell (student intern?) has been working on a web browser front-end for viewing and creating cellPACK models.

== Viewing cellPACK models ==

 * '''Open cellPACK models, fetching JSON files from web.'''
 * '''Open collada surface files used to represent cellPACK molecules.'''
 * '''Hierarchical collapsible list of model components, checkbuttons for display'''
 * '''Mouse hover to pop-up name of molecular component.'''
 * ''Geometric selection eg drag-select and select-within-shape.''
 * Animate layout of model from regular grids of component molecules.
 * Replace surface depiction of some molecules with atomic model.

== Creating cellPACK models ==

 * Simple interface to run cellPACK, place molecules on a surface or within a surface.
 * Export low resolution surfaces (hundreds of triangles) for pdb models.
 * Export multi-sphere bounds file for molecular components.
 * Specify axis for molecules embedded in surface (e.g. virus spike).

== Measuring properties of models ==

 * Measure statistical distribution of distances between molecules (vague).
