[Radiance-general] HDR Sky Camera @ LBNL's Flexlab

[Greg Ward]

Hi Joe,

Do you really need to do this?  The code for view angle calculations is not very straightforward, but if you are really motivated, you can convert the C code in the viewloc() routine found in src/common/image.c to the .cal language.

Cheers,
-Greg
