[Radiance-general] How can I...

[Jack de Valpine]

Hi Ali,

I will try to give you a few hints on this topic. To get geometry into 
Radiance one needs to export the geometry from their modeling 
application of choice into a format that can be readily converted to 
Radiance's format. From Autocad, one solution is to use radout which can 
be found on Georg Mischler's site:

    http://www.schorsch.com/download/radout/

Note though that this will only work up through Autocad 2000 as far as I 
know. However one of the nice things about this application is that it 
exports directly to Radiances file format.

Now if your mesh needs to have "mesh" type properties such as local U,V 
coordinates you will need to use an intermediate application such as 
Rhino or PolyTrans which can read in Autocad .dwg format files and 
export to .obj. This can then be converted with Radiance's obj2rad or 
obj2mesh command.

Now I am not clear on what you mean about the files being 
"automatically" updated. Material assignment is done based on the 
geometry groupings (such as by layer name or layer color are the two 
conventions available from radout). You will need to create a material 
file that defines materials for each element of geometry that has been 
exported.

Note, if you are going to use Radiance as part of your Thesis work, I 
would strongly urge you to get a copy of "Rendering with Radiance" which 
is loaded with a great deal of very useful information.

Regards,
