Question on scene specs (IGS files)

Post by urusei » Sat Aug 18, 2007 12:51 pm

Hello, this is my first post. Please excuse any typos, I'm not an english speaking person.

I'm looking for a complet list of all IGS files specs, all the possible parameters please. The PDF that comes with INDIGO's last release is very good, but some infos are missings, if anybody can help me it would be appreciated:

First, into the test scenes, what exactly are "Triangle_set"? I've tried to understand just looking at the code, but I'm having trouble finding any "Triangles" into the rendered images...

Second, beside the SPHERE, what others primitives can be implemented into a scene and the parameters for each of them?

Thanks for any reply.

Hi urusei,

First, triangle_set is written by the exporter, don't bother with that. It's geometry data.

Beside sphere there is plane, I think it is documented too. That's it. Oh, see the wiki (WIP) in the Documentation menu of the current page.

there also is a rect. - rectangular emitter (Area light), but it's barely used, as you usually simply use a single plane, to get that. :)


Note to the plane: Doesn't work with BiDir, as there are troubles with the combination of BiDirectional Rays and the infinite :)

triangle set describes a group of triangles, that all share a common material.

About the rectlight, seems it's not implemented like a mesh emitter within Indigo, is it more efficient ?

RectangleLights are probably very slightly more efficient in terms of sampling properties, yeah.

I know, it once was included in Blender to Indigo, but if I remember correctly, it wasn't included, anymore in Blendigo...
