[Radiance-general] Image mapping photos to the skydome

[G]

Galen,
If you know the camera lens angle of view you can simply use a rectangle at a distance.
You need the location in 3d of your POW when you take the photo.
Alternatively you could stitch a series of views to make a fisheye projection (for example with 'hugging’) or even better a cylindrical one.
Let me know if you need more on this

One of the objectives is to demonstrate how the visibility to the exterior scene changes with different types of glass (as exported from LBNLWindow), depending on tint, vlt, and interior reflection.  This is why having a realistic exterior scene is more compelling than whatever simplistic scene I would be able to model myself.
