hello,
I don't find a tutorial or a technical reference who can help me about the igs file syntax and semantic. Do anybody know where I can fint it?
For example if I have this piece of code:

Code: Select all

<background_settings>
  <background_material>
    <material>
      <name>background_material</name>
        <diffuse>
          <texture>
            <uv_set>albedo</uv_set>
            <path>C:\MyTexture.bmp</path>
            <exponent>1</exponent>
            <tex_coord_generation>
              <spherical>
                <rotation>
                  <axis_rotation>
                    <axis>0 0 0</axis>
                    <angle>1.6</angle>
                  </axis_rotation>
                </rotation>
           .... and so on ....

How can I set, for example, "<axis>" and "<angle>" parameters? What do they mean?

thanks for any kind of help!
bye!

Hi moraton, for what I can say axis is a 3d vector around wich the spherical projection is oriented/rotated, and angle is the amount of rotation expressed in radians.

1.6 radians ~= 90°+

Thank you, but what about the tutorial of igs syntax and semantic? Is there nothing?

Nothing official beside the technical documentation. Many code snippets can be found throughout the site, though. Check also the Indigo release threads where new functions were intoduced.

ISL is aimed at coders and operators with a former knowledge in shading bits.

Maybe you are just looking for the technical documentation, it can be found here:

It's not totally up to date, though.

I wasn't clear enough, sorry moraton: the technical reference PDF is also shipped with Indigo
