yes, I suspect so. Regards, Rene ________________________________

Hi,
Sorry for the off thread, if I can recover the vertex list, is it possible to
create runtime crater (cause by explosion)? Any examples out there?
Regards,
Cg

thanks for replying, but the problem is that the osg::Node* returned by
ReadNodeFile() is not a osg::Geode().

Hi Rene,
From you geodes, take the drawables, cast them into geometries and
recover the vertex list with getVertexArray.

Hey there,
I've been browsing the mail archive to find the answer to my
question but I haven't found anything at all. I basically want to manipulate
the vertices of a model loaded by the osgDB::ReadNodeFile() function.
ReadNodeFile() returns a osg::Node. I was hoping this might actually be a
osg::Geode, but apparently it isn't.
Reason I want to do this is because I have 1600 different
building models. But all of these building models are already positioned in
their correct position and rotation (instead of each building being built
around 0,0,0). So basically if I load my 1600 models and all position them on
0,0,0 I have a complete and perfectly aligned town. I want to move every
building back to 0,0,0 so that I can re-use them. I've already used osg to find
their position by finding the center of their bounding box. And now I want to
substract that position from the vertices of every building and save them.
Anyone know how to achieve this?
Thank you in advance,
Rene
