Re: [Algorithms] Lightmap Terrain

[Leigh M. <lei...@ro...>]

  I have seen people reply with many good ideas on this lightmap thing so I
am guessing that many people are going with lightmaps for terrain.  I am
wondering if these people have a fixed position for the main light source
such as a sun.  I am currently using vertex lighting as it was very quick to
get going and it looks good even with a LOD algorithm.  Are lightmaps being
generated as the sun moves?   Do the lightmaps light static objects also?  I
was also worried of loosing a multi-texture to lighting when I could use it
for noise or something else.  What about DOT3, does anyone have an idea how
fast it would be?
