Hi Omar,

line is related to the digest as well which breaks any threading that
mail tools provide. These too factors together make it difficult to

I'll add my public congratulations to yourself and Xuelei on
publication of OpenScenegraph 3.0 Beginners Guide. Writing a book is
a big endeavor, delivered on schedule too! Thank you for the kind

Hi,
I the osg::Manipulator example, there is no EventHandler Class as before but a
new handle function has been introduced in the Dragger code. How does it works?
I used to work with the prévious version which was using a classic pick system
built in a GUIEventHandler class.
Thank you!
Cheers

Hi,
I have loaded a 256x256 HeightField, created a HeightFieldLayer, and added it
as the ElevationLayer to a TerrainTile. Now, if I would like to go about
texturing patches of terrain, do I essentially need a separate TerrainTile for
each individual area to be textured? And if this is the case,
If you just need to create a high resoultion rendering from of a single
frame, you can modify the camera's projection matrix to capture many
smaller segments, something like this:
camera->setProjectionMatrix(projMat * osg::Matrix::scale(xSegments,
ySegments, 1.0) *

We're releasing our physics engine AGX Multiphysics for licensing. We use OSG

also use OSG.
AGX may be of interest to those of you who develop e.g. vehicle simulators or simulate other types of mechanical or m

Hi Martin,
I can't say what the problem is, the error could one of many things.
Does your hardware/driver support compressed textures, VPB by default
generates databases with compressed textures? Try a paged database
that doesn't use compressed textures.

I don't know if they are tutorails about this, but animation can be done with
OSG.
To set your animation, you can use blender for example and then, export to osg.
Then, use osgCal to perform animation and skinning.
