Hi, Maurus,
I think it's the order of the multiplies. It should be like vec*MatA*MatB, If
you want to apply an osg::Matrix on a osg::Vec. But I do not quiet know why
osg::Quat does not obey this: for a osg::Quat, the form quat * vec is used.___
Hello everyboy,
currently, I am trying to get some transformations working to display a
cylinder as a line of sight.
As you can see in the code below, I want to get the rotation represented by the
Quaternion q into the Matrix mat, but neither preMultRotate using the quat nor
multiplying as a
Hi,
It was the loading of the rotation Matrix, the Y-up Rotation just rotates 90
degrees on the wrong axis, but the animation was still working OK :)

Out of curiosity, what was the issue? The loading of the existing matrix into osg::Matrix
or the order of transformation or

Hi Ümit,
I try to use osg::Switch to insert all the data I have in the files( each file
in a separate node with his own transform matrix ), so I can switch the nodes
in each frame, but I don't know why it seems that the second and following data
I insert accumulates the previous matrix

Hi Paul;
So in OSG first of all I try to do it with a osg::Switch but seems that
this node accumulate the transformations... is that right?
What do you mean about osg::Switch. It's not specific feaute on accumulating
trasformation for osg::Switch as I know. It actual target is switching node
