Finding Objects or Features in LUNEX
  • How to Find Objects or Features in LUNEX

    Finding a target object in LUNEX is very easy.  We simply give LUNEX the selenographic coordinates of the object or feature and LUNEX will render the scene centered on those coordinates.

    In the home folder, copy the POV file:
    DEFAULT-SCENE-TEMPLATE.pov

    Then, rename that copy to:
    Langrenus-Crater.pov
    All subsequent changes in the copy will be made to and replace the default settings to render the new scene.


    We start with the default geocentric full moon.
    All subsequent changes in the copy will be made to and replace the default settings.

    For example, to render a scene centered on the crater Langrenus, we obtain the coordinates for the crater Langrenus from the table of crater coordinates and enter them into the LUNEX code block.

    For the crater Langrenus, those selenographic (camera) coordinates are:
    CamLat = -8.9
    and
    CamLon = +61.1


Location of the crater Langrenus. 

  #declare CamLat =   -8.9; // Langrenus
  #declare CamLon =  +61.1; // 127 km (79 mi)     Near Side E
The camera (eye) is now centered directly above the crater Langrenus on the right
side of the moon, in the eastern hemisphere.

To make it more dramic, let's change the relative phase angle to 250.0 degrees. 
  #declare PhaseAng = 250.0; // Range: 0 to 360

View of the crater Langrenus at relative phase angle 250.0 degrees.

You can center on any feature by simply setting the cam coordinates to that feature
and adjusting the relative phase shading to whatever you think looks best.
