ivbinary_maker

v0.3.dev exports for ivoyager_core v0.0.19.dev v0.2 exports for ivoyager v0.0.16.

Converts raw source data into binary and texture files for use in I, Voyager.

• Asteroids - Generate asteroid binaries.
• Rings - Make a '1-spatial-dimension' texture sampler for rings.shader!
• Comets - PLANNED.
• Stars - PLANNED. (Stars as shader vertecies!)

Download raw data files into folders described below:

source_data/asteroids

Required!

Download from: https://newton.spacedys.com/astdys/ (Asteroids - Dynamic Site)

Proper elements:

• all.syn - Numbered and multiopposition asteroids; the catalog contains the Main Belt and Hungaria asteroids.
• tno.syn - Trans Neptunian Objects; the catalog contains TNO's.
• tro.syn - Trojan asteroids
• secres.syn - Main Belt asteroids locked in secular resonance. Please note that in this file the proper eccentricity is replaced by Delta e, the amplitude of resonant libration in the eccentricity. Thus the values in that column cannot be compared with those of the other files. In the visualizer the resonant objects are placed in an empty region with e between 0.7 and 0.8. with the convention e=Delta e + 0.7.

Osculating elements:

• allnum.cat - Numbered asteroids orbital elements, one line format, epoch near present time.
• ufitobs.cat - Multiopposition asteroids orbital elements, one line format, epoch near present time.

Download from: https://sbn.psi.edu/pds/resource/discover.html

• discover.tab - Has name and discoverer for numbered asteroids as of 2008. File from EAR-A-5-DDR-ASTNAMES-DISCOVERY-V12.0/data.

Not used (yet)

Family data:

• all_tro.members - Individual asteroid family membership. Note only asteroids belonging to some family are listed in this file; Trojans are included.
• all_tro.famtab - Asteroid families summary table for each family. Trojan and Griqua families are included.
• all_tro.famrec - Family status for each asteroid with synthetic proper elements. Status=0 indicates the asteroid is not in any family, according to the current classification. Trojans are included.
