hi dudes^^

me and my friends are supposed to build a sunsystem with povray... the
constesllation of the planets was no big deal for us ;) but the appearance
of the planets is far from being called good... we wanted to use a jpg as
texture for the planets, but cause we're n00bs with povray we suggested to
ask you for help... how are we supposed to do that? or is it an
unrealizable thinking?

thx for every post

It depends on what kind of textures you have and how you want to apply them.
Are they just plain photos, or are they spherical maps (like a landmap of
the entire planet)? Such landmaps can be put onto the spheres for the
planets like this:

sphere{0,1 pigment{image_map {jpeg "earth.jpg" map_type 1}}}

Then you just scale the sphere to your desired size and translate it to your
desired location.

Regards,
Tim

Follow Tim's instructions, and here is a good image to use:

Euuch... where did that code come from? ;)

Problems....

1. sphere{sphere doesn't make any sense - "sphere{" should be followed by a
position (e.g. <0,0,0> or just 0), and then a diameter

2. you've got two pigments applied to your sphere, and not in a good way

3. loads of other stuff...

K.I.S.S.

Make sure that earth_land.jpg is in the same directory as your scene file,
and try this code:

camera {
  location  <0.0, 0.0, -4.0>
  look_at   <0.0, 0.0,  0.0>
}

light_source {
  <0, 0, 0>            // light's position (translated below)
  color rgb <1, 1, 1>  // light's color
  translate <-30, 30, -30>
}

sphere{
 0,1
 pigment{image_map {jpeg "earth_land.jpg" map_type 1}}
 finish{diffuse 0.75 ambient 0.01}
}

thanks for the great help... works fine... =)

but does anyone know where to get some other textures for the rest of the
planets... i can't find something for mars, sun, jupiter, etc...

matane... ;)

You can also get real large-scale maps from earth from NASA:
