  1. 1. Update
  2. 2. Installation
  3. 3. Kepler - Solar system body placement
  4. 4. Astropix - Planetary rendering effects

1.  Update!!

EDGE v2.0 provides an atmosphere, so if you upgrade you will want to disable either the astropix atmosphere or the one provided by EDGE. Also, it looks like there is an invalid enumeration in one of the plugins that is being reported by dsp_planet2 in an error message similar to the following:

dsp_planet2.c - line 6073) generated GL_INVALID_ENUM error!

I believe Tom has an update to fix this, but you'll need to contact him. —FG

2.  Installation

These two plugins are meant to be run together, but don't have to be.

To install them, download this file and extract in your "userdata" directory.

Then, just add the following two lines in the top postload section of user.cfg:

POSTLOAD
 {
      "${USERDATA}/configs/kepler.cfg"
      "${USERDATA}/configs/astropix.cfg"
 }

| ## 3.  Kepler - Solar system body placement

The kepler plugin manages planetary placement in the solar system. Inertial as well as fixed coordinate systems are available for each planet.

Planetary bodies are positioned according to the Julian time, which is tracked by Kepler. Users can also drive this Julian time from their sim as well.

Another feature this plugin provides is NULL frame relocation. This lets the NULL frame of the scene be located at the planet which the user requires the most precision from. For example, once a spacecraft gets closer to the moon than the earth, the sim developer could have the sim tell the graphics to reorient the scene so that NULL is located at the moon instead of the earth.

The astropix plugin currently enables some panetary rendering effects such as earth atmosphere, stars and the night side of the earth. It can also display planet orbit lines and celestial grids.
