[Radiance-general] Clipping in a parallel view?

[David Smith]

Hello raytracers,

I've occasionally come across object clipping in some parallel views
without setting any clipping plane. I've always assumed that the
camera for parallel views was at infinity and everything in the scene
was visible to it. I've included an example below that clips the
corner of a rectangle. Is there a workaround to this, say, a simple
conversion to a parallel view from very far away? Am I overlooking
something? I'm using Radiance 3.8, by the way.

Thanks in advance. Cheers,
--Dave
