Re: [PyMOL] Light Command Details needed
Hi Sean, I could not find a way to search the archived sourceforge messages, It is indeed easy to miss but at the bottom of every message there is a link to the searchable archives: http://www.mail-archive.com/pymol-users@lists.sourceforge.net Henning On Thu, Aug 20, 2009 at 10:50 PM, Sean Mooresemo...@mail.ucf.edu wrote: Hello, I could not find a way to search the archived sourceforge messages, so I apologize if this has been asked and answered.

Hi Sean, I ended up using light, [1,5,-100]. I know these are X,Y,Z coordinates, but relative to what origin and in what units? After wasting way too much time, I concluded that the values might be Angstroms relative to the eyes of the current view. In examples I found online, the numbers are small, so this doesn't make much sense. These values are the x,y,z components of the light vector. The units are irrelevant ( [1,1,-1] == [2,2,-2], at least to my eyes judging the output images). I don't believe there's a defined origin, either (it's not a point light source).

Re: [PyMOL] Light Command Details needed
The light and lightN settings are direction vectors, not coordinates. Intensity (reflect setting) is averaged across all such directional sources. It has recently been suggested that we need better control over lighting. Cheers, Warren -- Warren L. DeLano, Ph.D. war...@delsci.com (Sent from a mobile device. Please forgive brevity and/or typos!)
