Hello,
I am trying to find the right way to update my 2D camera after a window
resize. I check all the mailing list but I can't find the trick.
Maybe somebody can help.
I try the followings
1. Setting up the camera:
...
camera2d = new osg::Camera;
Hello,
I am just experimenting to load huge amount of models.
I have a set of ~50.000+ single models (parts) stored on disk in a
folder structure in .osg or .ive format, converted from a cad system
format. To each of the models I have a transformation matrix to position
the model in the scene.
Hello,
I am following

to build VRML plugin
Normally I am using Eclipse CDT4 - MingW environment on my Windows PC. But for
this task I have installed cygwin with all needed packages to build the three
needed libs:
Hello Jean-Sébastien,
it no big deal for me, coding around OpenSceneGraph is my hobby ...
... to keep a bit on track and good for my brain.
A made some other code to select geometry objects within a box.
The scenario is that I place 1.000 cows.osg (transform + scale) in a world cube

Hello Peter,
Combine your two approaches: First check the planes of your
Polytope against the bounding volumes of your nodes.
Do not use intersect but check if the volume is
properly on the inner side of the plane. If this
test passes for all planes you don't need to generate
all the
Hello,
I am following the osgkeyboardmouse example and would like to implement a
selection by a rect (like rubberbanding).
I thought PolytopeIntersector in CoordinateFrame WINDOW is the right choice
for it.
Hmm,
but my problem is that I will get always intersection when a model is loaded
Hello Jean-Sébastien,
hey, you are a hero ... It's working, fine.
Do you have any experience in terms of performance when expanding a rect
(dragging like a rubberband) over a huge number of models (ex. hundreds or
thousands of cow.osg) and computing the intersection in a EventHandler
Hello,
I am experimenting around a ClipNodeBox and selection by picking of Nodes
inside this box. Is there a elegant way to limit the
computeIntersections(ea.getX(), ea.getY(), intersections,
0x) method to take my ClipNodeBox into account?
I try
