OH WOW, cool. :) Don't mention this in the book, obviously, but as soon as my condition allows (the medication I take for my CML really knocks me out; it's like chemo in a pill) I will be working more on osgWidget. I won't be changing the API too much, but I will be reducing a lot of the redundancy and abstracting a few things (such as making Widget an interface rather than the Quad implementation I currently use). However, only osgAnimation appears to have a dot osg plugin. osgVolume and osgWidget apparently do not define any classes that are supported by dot osg. Looking closer, I see that there is no dot osg plugin for osgManipulator or osgGA either. Do we need a new category for OSG-based libraries that aren't NodeKits? Or do I need to change my definition of NodeKit to be more inclusive? Thanks for any suggestions.

Re: [osg-users] Defining NodeKit
Cool. Jeremy, could you possibly write a couple lines that capture the spirit and intent of osgWidget for inclusion in my revision? If so, thanks in advance. Here's the text I have so far, so you can get a feel for what I'm after: NodeKits extend the concept of Node, Drawable, and StateAttribute objects, and can be thought of as extensions to the osg library in core OSG. NodeKits must do more than derive from an OSG class. They must also provide a dot OSG wrapper (an OSG plugin to support reading from and writing to an .osg file). As a result, a NodeKit is composed of two libraries: the NodeKit itself, and a dot OSG wrapper plugin library. OSG v2.8 has 10 NodeKits. . The osgAnimation library TBD. . The osgFX library-This NodeKit provides additional scene graph nodes for rendering special effects, such as anisotropic lighting, bump mapping, and cartoon shading. . The osgManipulator library-This NodeKit contains several classes for manipulating selected objects in the scene graph. . The osgParticle library-This NodeKit provides particle-based rendering effects, such as explosions, fire, and smoke. . The osgShadow library-This NodeKit provides a framework for supporting shadow rendering techniques. . The osgSim library-This NodeKit supports the special rendering requirements of simulation systems and OpenFlight databases, such as terrain elevation query classes, light point nodes, and DOF transformation nodes. . The osgTerrain library-This NodeKit provides support for rendering height field data. . The osgText library-This NodeKit is a powerful tool for adding text to your scene. It fully supports all TrueType fonts. . The osgVolume library TBD. . The osgWidget library TBD. In addition, the osgGA library provides a cross-platform interface to events and input devices such as window resize, mouse button, mouse motion, and key press events. I appreciate your assistance with filling in the blank.

Re: [osg-users] Defining NodeKit
Hi Paul, I am a bit busy to help you right now to write on osgAnimation, you can find information about osgAnimation http://www.openscenegraph.org/projects/osg/wiki/Community/NodeKits/osgAnimation It's not complete but will maybe help you to have an idea.

Re: [osg-users] Defining NodeKit
osgAnimation, osgWidget and osgVolume all have plugins that support reading and writing of extended .osg files. These are all full NodeKits, as they all directly extend the scene graph nodes, drawable + state. Thanks for the correction. I didn't see the build target for the OSG support for those, but I do now. Eyesight continues to fail... :-( -Paul ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
