Hi, Yes the operator run well, but the translation in the matrix in ignored (4th colomn)... I have a translation matrix, I use the operator on a vec3... and the result is a little vector (from ~100 unit lengh to 0.0001 unit, with a translation of ~3000,-2000,1500)
I do not understand all... 2008/12/10 Thrall, Bryan <[EMAIL PROTECTED]> > Vincent Bourdier wrote on Wednesday, December 10, 2008 10:31 AM: > > > Hi, > > > > Just a problem of math & OSG : > > > > I have > > * a vec3d point in relative coordinate > > * a matrix to transform in world coordinate > > > > I need to make something equivalent to vec = mat * vec ... > > But the 3d vector cannot be trnasformed by a matrix (4*4) ... > > Matrixd provides Vec3d operator* ( const Vec3d& v ), so you should be > just fine with vec = mat * vec. > > -- > Bryan Thrall > FlightSafety International > [EMAIL PROTECTED] > _______________________________________________ > osg-users mailing list > [email protected] > http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org >
