Re: [ggt-devel] setRotX()?

[kevin m. <ke...@su...>]

If you have come code (or pseudo code) in mind, post it to the list, we'll
take a look to see what specific functionality you need, and if it is
something that we forgot in gmtl, we'd be happy to include it.


For an AxisAngle, isn't rotation about one axis simply setting the axis
and the angle?  I'm not sure what more you could want.  Maybe when you
post the code I'll understand better.
