What's that? - Basics -
The SkyboxViewer is an OpenGL program for displaying and examining 3d scenarios from a fixed point of view. Therefore 6 images with defined filenames (see below) will be loaded.
With mousepad and key commands we can change the viewing direction in full 360° panorama, right and left, up and down and we can zoom in and out.

To understand what a Skybox is, read my tutorial on
Skyboxes with POV-Ray.
The 6 images for the six faces of a skybox can be made from POV-Ray scenes (as descriped here) or also from Terragen scenes and with many other 3d programs.

 
An animated Skybox-View
Arrangement of the 6 Skybox images:
 
 
  The arrangement of the 6 images:
                _top
       _left  _front  _right  _back
                _base
The SkyboxViewer naming conventions for the skybox images:
<skyboxname> is a free chooseable name according the naming conventions
<ext> defines the image type (BMP, JPG, PNG or TGA)
        Supported image file formats:   ----------------------------------------------------------------------
        *.bmp   Windows Bitmap
        *.jpg   JPEG - Joint Photographic Experts Group
        *.png   Portable Network Graphics
        *.tga   TARGA File Format (only unkompressed image files are supported)
        ------------------------------------------------------------------------------------------------------------------------
The 6 skybox images has to be named as follow:
  <skyboxname>_front.<ext>
 front side image
  <skyboxname>_right.<ext>
 right side image
  <skyboxname>_back.<ext>
 back side image
  <skyboxname>_left.<ext>
 left side image
  <skyboxname>_top.<ext>
 upper side image
  <skyboxname>_base.<ext>
 bottom side image
The program seeks for skybox image series only in a subdirectory named "Skyboxes".
Multiple skybox series were found in the alphybetical order.
This implies the following directory structur:
AnyDirectory/
Skyboxes/MySkybox1_back.jpg
MySkybox1_base.jpg
MySkybox1_front.jpg
MySkybox1_left.jpg
MySkybox1_right.jpg
MySkybox1_top.jpg
