// Ada as rotating planet. A hack. Maybe wrong approach etc.

//EXAMPLE OF SPHERE

//Files with predefined colors and textures
#include "colors.inc"
#include "glass.inc"
#include "golds.inc"
#include "metals.inc"
#include "stones.inc"
#include "woods.inc"

//Place the camera
camera {
  sky <0,0,1>
  direction <-1,0,0>
  right <-4/3,0,0>
  location <0,0,11>
  look_at <0,0,0>
  angle 15
}

//Ambient light to "brighten up" darker pictures
global_settings { ambient_light White }

light_source { <-9,-1,-9> color White*16 }
background { color Black }
sphere { <0,0,0>, 1
  // pigment { color rgb <0.005, 0.005, 0.005> }
  pigment { image_map { gif "ada.gif" map_type 1 } }
  finish { ambient 0.5 diffuse 10 reflection 0.9 }
  rotate <0,65,0>
}

// Get ada.gif from https://twitter.com/adaplanet1 
// That is, I converted that png to gif. Or use tga
