Description Frank Weed II 2006-09-20 13:01:08 PDT
<lambert> is currently defined as "The reflected color is calculated simply as: color = emission".  This appears to be a copy & paste error from <constant>.  The Introduction section should also be changed.
Comment 1 Mark Barnes 2006-09-22 18:31:15 PDT
Daniel please supply corrected text.
Comment 2 Daniel Horowitz 2007-03-29 02:33:02 PDT
color = <emissive> + 
<ambient>* Σ(AmbientLights, LightColor) + 
<diffuse>* Σ(OtherLights, LightColor*max(NdotL, 0))

where OtherLights includes all other light types (point, direction, spot)

Daniel the descriptive text is also incorrect. Can you provide paragraphs for Introduction, Concepts, and Remarks?
