PyRad

Replacements in Python for some of the shell/Perl scripts included with the Radiance lighting simulation package.

Usually the scripts are drop-in replacements for the originals, but with some additional functionality.

###Design goals

• usage instructions (-H)
• progress report (-V)
• dry-run mode (-N)
• detailed error diagnostics
• compatible with Python 2.7 and Python 3.x
• self contained (all functionality in one file)
• truly cross-platform (no external dependencies other than Python and Radiance)
• direct process management (no intermediate shell calls)
• immune to whitespace in file names
• tamper-proof use of temporary files

###Currently implemented

• falsecolor.py - Make a false color Radiance picture
• phisto.py - Compute foveal histogram for picture set
• rlux.py - Compute illuminance from ray origin and direction
• pveil.py - Add veiling glare to picture

###Contributions welcome

• more scripts (implementing the same design goals)
• systematic test cases (only casually tested so far)
• Wishlist items (with specification if original is undocumented)
