[Radiance-general] oconv and rtrace_dc warnings for non-planar vertices

[Ramana Koti]

Dear all,

I am using DAYSIM, not radiance directly.

When the simulation begins to run, there are these two different types of
warnings:

oconv: warning - non-planar verterx for polygon "f_1719_0" (this happens for
20 or so polygons)
rtrace_dc: warning - non-planar vertex for polygon "F_1636 (Can't see the
rest of it, this happens for probably the same polygons but not in the same
order)

I used the SketchUp to Radiance su2rad plugin to export geometry from a
sketchup model and I had to start the simulation before DAYSIM refreshed
geometry display since it was taking too long to do that.

How serious are these warnings and why are they occuring?

Thanks,
