hi,
mmh, i ve tried it with (0,1,0) but it did not function (false direction).
another confusing point (that perhaps leads to my failure):
after i invoked
transform3d.lookAt(p1,p2,v); t
he view is not located in p1. so i do another operation:
transform3d.setTranslation(v1);
where v1 has the same koordinates as p1. now the view is on the right location (but
with bad direction).
shouldnt after 'lookAt' the view locate at p1 ?
