A structural model of the earth in scale, using a graphic from NASA for surface appearance.

Graphic is here: http://veimages.gsfc.nasa.gov//7100/world.topo.bathy.200401.3x21600x10800.png

Convert to pix file called world4.pix and store that pix file in the same directory with earth.g:

png-pix world.topo.bathy.200401.3x21600x10800.png > world4.pix

Model should be fairly closely to scale - used polar and equator radial values from NASA. Also includes internal structural elements and troposphere, stratosphere, mesosphere atmospheric layers.

Updated to 1.1 - change default rotation of sphere so more interesting surface features are present in default view, and tweak atmosphere shaders.
