Re: [ggt-devel] Vec*EulerAngle?

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

most likely that operation is undefined.  i.e. there is no xform() or
operator* for Euler/vec

try matrix or quat.  remember you can convert euler to matrix

newvec = gmtl::xform( gmtl::makeRot<gmtl::Matrix44f>( gmtl::EulerAngle(
4,5,6 ) ), oldvec );

try that...




I'm wondering if we should add a vec operator to the AxisAngle class that
returns a pointer to the internal vec memory - since the vector part is in
yzw, we'd cast the &mData[1] to a Vec3f*
