Display settings

These settings in the cometparams.ini affect the way data is displayed. There are two display outputs, bitmaps (2D) and VTK (3D). Bitmaps are automatically created during the initial calculation run, but usually start only after the symmetry breaking direction is determined (since this determines the observer position). Bitmaps can also be produced after the initial calculation run is complete with comet post, and VTK output is produced only after the initial calculation run with comet view or comet vtk:

Producing Bitmaps

You can call the bitmap processing with

comet post 0:0

where 0:0 processes all frames, or a range of frames if specified.

Producing VTK output

You can call the VTK processing either interactively with

comet view 300:300  

Note only a single frame can be specified for the interactive view.

or in batch mode with

comet vtk 0:0

VTK can also produce vrml files to import the 3D models into other software (e.g. Acrobat 3D) by calling with one frame only

comet vtk 300:300
