Hi,
I'm working in a engineering project which is essentially a design tool. A main
GUI gives the user the ability to choose let's say the geometry of some
machine. It's always the same object but it can have different geometry
characteristics (larger, shorter, wider, etc). Once we have the geometry from
the GUI our code has an engine to simulate the dynamics of the problem given
some forces acting on the machine etc. After the code has calculated the
physics we want
to dump the results on a osg based VR.
So we have a 3D file, from some 3D tool, let's say 3Ds. This specific 3D model
must be prepared for a given set of geometric characteristics of the machine, I
mean, you have to draw your model so you need sizes, etc. As I mentined before,
If I change the size of some part in the GUI, I want my OSG model to change
too, otherwise, when I dump the results on the VR (now physics model and 3D
model have different characteristics) the animation is not correct. I hope you
can understand what I mean.
So here is the question. What is the best way to resize a model I load using
osg::Node* track = osgDB::readNodeFile("track.ive"); where track was initially
track.3ds and I convert it to ive using OSGExp
or I can even do this: osg::Node* track = osgDB::readNodeFile("track.3ds");
using the new ability of OSG to load directly 3ds files? Let's put it in other
words. How can I access parts of the node track (in my example) to change their
sizes? or at least if that's not possible to resize or rescale the whole file?
Thank you so much!
Cheers,
Juan
