Hi all,
Just a simple question, I have now found a need to use LookAt
functions, but I don't understand something, I create a matrix using
lookAt, but when I call getlookAt, it does not give the same results
back I originally used when creating it. Any ideas?
Code :
osg::Vec3d eye(0.0, -89.0, 0.0);
osg::Vec3d cnt(0.0, 0.0, 0.0);
osg::Vec3d up(0.0, 1.0, 0.0);
M.makeLookAt(eye, cnt, up);
M.getLookAt(eye, cnt, up, 89.0);
The results I get are all --1.#IND0000000000000 (not a number)
It is rather obvious that the up and the eye vector are parallel. In
order create a valid view matrix they should be perpendicular.
cheers
Sebastian

PS: I am attending Sig-graph 2014 this year, so it will be great to
finally meet some of the wizards from OSG.
