amblient light
In the class Display there are some methods relatated to amblient light, but I'm confused about what are they used for, the methods lists here:
ambMode
ambSoft
ambJitter
ambNormal
ambHalfRes
ambPower
ambColor
ambContrast
ambRange
ambScale
ambBias
Could u tell me some principles behind those pls ? Otherwise It will be nice if U could tell me which articles to read to learn those. With the background knowledge I can use them better.

1. It's called ambient 
2. Look into the headers:
Code:
// Ambient Light
Display& ambMode (Byte mode ); Byte ambMode (){return _amb_mode ;} // set/get Ambient Mode (AMBIENT_MODE, default=AMB_FLAT)
Display& ambSoft (Byte soft ); Byte ambSoft (){return _amb_soft ;} // set/get Ambient Softing ( 0..2 , default= 1)
Display& ambJitter (Bool jitter ); Bool ambJitter (){return _amb_jitter ;} // set/get Ambient Jittering (true/false , default= true)
Display& ambNormal (Bool normal ); Bool ambNormal (){return _amb_normal ;} // set/get Ambient Normal Map Use (true/false , default= true)
Display& ambHalfRes (Bool half_res); Bool ambHalfRes (){return _amb_half_res ;} // set/get Ambient Half Resolution (true/false , default= true)
Display& ambPower (Flt power ); Flt ambPower (){return _amb_color.avg();} // set/get Ambient Power ( 0..1 , default= 0.4), this is equivalent to using ambColor with 1 value
Display& ambColor (Vec &color ); Vec ambColor (){return _amb_color ;} // set/get Ambient Color ( 0..1 , default= 0.4)
Display& ambContrast(Flt contrast); Flt ambContrast(){return _amb_contrast ;} // set/get Ambient Contrast ( 0..Inf , default= 1.2)
Display& ambRange (Flt range ); Flt ambRange (){return _amb_range ;} // set/get Ambient 2D Range ( 0..Inf , default= 0.3)
Display& ambScale (Flt scale ); Flt ambScale (){return _amb_scale ;} // set/get Ambient 3D Scale ( 0..Inf , default= 2.5)
Display& ambBias (Flt bias ); Flt ambBias (){return _amb_bias ;} // set/get Ambient Bias ( 0..1 , default= 0.3)
(sry for bad formatting, Display.h)
regards,
Kevin

RE: amblient light
Kevin,
Does the comment "set/get Ambient Jittering" really explain what it is to you? I'm with the OP on this. I looked in the code headers and still don't really know what it does.

RE: amblient light
for more info about the parameters you can launch WE,
load some level
disable sun light
put ambient light to maximum
and play around with the parameters of AO
youll see what it does.
