Hi.
In my application, I use mostly ComponentTransforms, as they are better
suited for my purpose and "easier" to hande (in my particular case).
However, from time to time, I also use the setMatrix() method.
Unfortunately, setting the matrix directly on a ComponentTransform
leaves the translate, rotate etc. fields of the ComponentTransform
untouched -> they are wrong afterwards.
I added this small piece of code to the ComponentTransform (of OpenSG
2.0, but 1.x had the same problem AFAIR) changed method to overcome this:
void ComponentTransform::changed(ConstFieldMaskArg whichField,
UInt32 origin,
BitVector details)
{
if((whichField & CenterFieldMask ) ||
(whichField & RotationFieldMask ) ||
(whichField & ScaleFieldMask ) ||
(whichField & ScaleOrientationFieldMask) ||
(whichField & TranslationFieldMask ) )
{
editMatrix().setTransform(getTranslation (),
getRotation (),
getScale (),
getScaleOrientation(),
getCenter ());
}
else if(whichField & MatrixFieldMask)
{
OSG::Vec3f translation;
OSG::Quaternion rotation;
OSG::Vec3f scale;
OSG::Quaternion scaleOrientation;
OSG::Vec3f center;
getMatrix().getTransform(translation, rotation, scale,
scaleOrientation, center);
_sfTranslation.setValue(translation);
_sfRotation.setValue(rotation);
_sfScale.setValue(scale);
_sfScaleOrientation.setValue(scaleOrientation);
_sfCenter.setValue(center);
}
Inherited::changed(whichField, origin, details);
}
If this is the right way to do it (my mostly single threaded app shows
the right values with it), could please anybody add it to the
repository? Ot otherwise, if this is not correct, fix it accordingly?
Thanks,
Dominik
