Re: [ggt-devel] meeting notes GMTL

[Kevin M. <ke...@vr...>]

how is a point one?  it is geometry.  but you do math on geometry..
so you do math on color too...  light/color is very mathematical...

the only reason not to, is if we wanted a geom extension lib to gmtl, then 
we'd put color texture, light, material, etc  in there....

which would be very logical extension...
