[enchancement] Try to design a even simpler but more powerful configuration file format for experiment #2

Closed liusida closed 3 years ago

liusida commented 4 years ago

Currently we are using VXA/VXD files as configuration files. The main problem is that this legacy format cannot support arbitrary initial position/orientation/velocity etc., everything needs to start from a lattice.

We should design a new file format so that we can define what initial condition we need for our experiment.

The VXA/VXD format should be preserved since we have experiments already written in that format.

Low priority, but if we redesign the file format, one thing that we might want to think about is creating a symbol/expression that indicates there is no material in this layer for N consecutive voxel slots. This would save a good amount of IO time when simulating high resolution bodies and/or sparsely filled worlds (e.g. petri dishes).
