Hi, I'm writing applications for use in the textile development. I have a 3D simulation for meshed textile fabrics. Usually they are based on repeats of some cm/inches size. For display of a large piece of fabric I create the geometry of the one repeat and show it multiple times by use of many transformations all referencing the one geometry. The transformations place one repeat beside / above the other. This gives a large 3D presentation of the fabric.
But this one is "flat" because it has no "wavy" behaviour as you can see i.e. on curtains. My question: How does OSG handle my data? Is the one repeat geometry data given to the graphics card and all visualized repeats/transformations are interpreted on the graphics card? Or are all the transformed vertices created outside the graphics card? So how can I implement a non-linear transformation on the complete fabric? All transformation classes I found are only linear transformations. Or can I use some callback mechanism for that? Just mapping some texture doesn't work in this case. Thanks for any hints and ideas. - Werner - _______________________________________________ osg-users mailing list [email protected] http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
