Hi Jae, In general OpenGL attributes are clapped to 0 to 1 range. I have to recommend that you do some reading up on glLight on the web as it'll do a much better job of explain things than I can do.

Hi everyone. This maybe very simple for most of users here. But I am fairly new to OSG or openGL, so some help would be great. I have been playing with light recently and i know diffuse, ambient etc. attributes are between 0 and 1. However the light was not bright enough and I did not wanted to add extra lights as the Virtual World is very vast, so adding more lights means lots of light. So out of curiosity i made the attributes to 255 and when i rendered the scene the light got a lot brighter than before. and I was wondering what is going on? if i make values to 255 would that be light with value 1(which is maximum from what i know) * 255 or the maximum values is not 1? but another large number? again apology for simple question thanks in advance Jae ________________________________ FREE pop-up blocking with the new MSN Toolbar MSN Toolbar Get it now! _______________________________________________ osg-users mailing list [email protected] http://openscenegraph.net/mailman/listinfo/osg-users http://www.openscenegraph.org/
