Aw: [Radiance-general] RE: Sketchup exporter script

[Mardaljevic John]

Hi Rob,

My SU model was only a 1/3 the size of yours: about 26Mb (Edges  
124168, Faces	60278).  The Radiance export took about 13 mins on a  
2.16GHz C2D MB (2Gb RAM).  The exported rad file was of size 13Mb and  
contained 60278 polygons.  For comparison, exporting the same model  
to Radiance via 3DS (& MGF) was much quicker but gave a rad file of  
size 38Mb with 188043 polygons (because of the conversion to  
triangles, of course).

The smaller rad file did produce a number of "non-planar vertex"  
warnings (as one might expect).  I haven't tried out the model much  
since I would need to first change all the material colours in SU to  
match the scheme used for the layers.

Hats off to TB for this very handy utility!

-John
