Hi Xavier,
for the translation you can use the matrix directly, perhaps we should
add a getTranslate() method.
Real32 tx = evol[3][0];
Real32 ty = evol[3][1];
Real32 tz = evol[3][2];

hello all,
I'm doing computation on the camera world and when i want to extract the
translation of my matrix, as i have to do a "getTransform" i got the
quaternion too.
My probleme is that i got actually an OpenSG warning with this
quaternion : "MatToQuat: BUG: |quat[4]| (1.012117) >> 1.0 !" wich slow
my application ( "fprintf(stderr "...)
How can i fix that ?
My code :
Matrix mCam;
cameraPtr->getBeacon()->getToWorld(mCam);
Matrix mInvCamera = mCam;
mInvCamera.transpose();
Matrix evol;
evol.setTransform(Vec3f(temp[0],temp[1],temp[2]));
// now get tranlation on world cam.
evol.mult(mInvCamera);
evol.multLeft(mCam);
evol.getTransform(translation, rotation,
scaleFactor, scaleOrientation);
...
Regards,
Xavier
