I like for example let areas blink or fade. change colors depending on elevation or user settings in realtime. Beside that I like to draw paths onto my elevation map like a circle and get elevation data of my height map at the position along the circle. It would also be great to manipulate the circle size and position. I think for the manipulation I can use osgManipulator class. But for the measurement I am not sure what i should use. I am not sure how customizable VPB or osgEarth are and if it is possible to change all the environment variables which are set by default?

This turns path (sometimes called vector graphics) rendering into first class drawables in OpenGL. Honestly, it's one of the coolest things I've seen in a while, and naturally--given my interest in OpenGL UIs--I began researching it and putting together a NodeKit for OSG. You can find it (in its infancy) here: http://osgnvpr.googlecode.com Run the example thusly: # osgnvprviewer # osgnvprviewer --perspective ..and notice how that no matter what the resolution, scale, or projection, the objects are rendered clear and crisp. There is also support for glyphs inside of GL_NV_path_rendering, so I will very soon be adding support for this style of text rendering into osgPango (and possible, osgText::TextNode). I've only just begun exploring this, and I'm mainly sending this e-mail to see if there is any professional interest in seeing this NodeKit mature in a timely fashion. I don't know if this is outside the allowable etiquette of the lists, but in full disclosure I'm looking to fill some free time by seeking funding for development of by those who would not only use these features but could benefit from being able to influence their development and pace! If this is inappropriate for the lists, just let me know and I'll be sure and keep my peddling to a minimum from here on out. :) At any rate, I'll continue to work on osgNVPR regardless, alongside devleopment of osgCairo/Pango/Widget and the recent TextNode submission. (Can you see a pattern here? All OSG interface development tools...) Some notes: - NV_path_rendering introduces a new kind of rendering style for its path objects. This doesn't map 1:1 to any existing usage of osg::Drawable, though I am able to hijack the compileGLObjects() method to get what I need. :) - BoundingBoxes are calculated with an extension call, but in order to use the extension I need a contextID (provided via either a State object or RenderInfo object). Unfortunately, these are difficult to get to at times, so CameraManipulators cannot properly determine a home position unless the Path has been compiled. ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org -- Mike Weiblen -- Black Hawk, Colorado USA -- http://mew.cx/ ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] tessellation shaders supported?
Hi, VertexProgram/FragmentProgram are for the older assembly-level programmability with ARB VP/FP. osg::Shader is for the newer GLSL programming interface. osg::Shader would be the place to add support for new GLSL shader stages such as tessellation. cheers -- mew -- Mike Weiblen -- Black Hawk, Colorado USA -- http://mew.cx/ On Wed, Sep 22, 2010 at 11:05 AM, Waldemar Schwan waldemar.sch...@iais.fraunhofer.de wrote: Hi, my want to use the new tessellation control and tessellation evaluation shaders that are new in OpenGL 4.

I noted that *new* osg::Shader( osg::Shader::GEOMETRY, geomSource ) actually uses open GL constants (http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/include/osg/Shader#L87). Since osg::Shader seams pretty generic is it a good idea to just use the matching GL constant ( something like GL_TESSELLATION_CONTROL_SHADER or so)? I guess my question is: How do I use tessellation shaders with OSG?

Submit a cool OSG based demo and you can win! As you may know, VT MÄK is the vendor of the VR-Vantage visualization product line, which is based on OSG. We would like to invite you, the members of the OSG community, to participate in a visualization innovation contest that we are sponsoring. We are offering cash prizes of up to $1,500 for the winners! http://www.mak.com/vrvcontest/ All you have to do is build something that demo’s well! It could be code that you’ve written or a 3rd party nodekit that you’ve integrated, or a cool terrain and scenario… Just build a cool demo using VR-Vantage and you could win! In order to be eligible, your demo must run within the VR-Vantage framework that we've built on top of OSG. We will provide free temporary runtime and developer licenses of VR-Vantage to those who intend to participate in the contest, along with some basic support to help you understand how to fit your OSG-based code, models or simulation in. Entries must be submitted by Oct 31st, 2010 (before 11:59pm). Winners will be announced to the OSG mailing list (and at the IITSEC Tradeshow) on Nov 29th, 2010. Here are the details: 1) By submitting an entry, you are agreeing to allow MAK and our sales distributors to use and promote your work - to show it at tradeshows, reference it on our web site, capture and show video and screenshots, etc. The idea is that we want to be able to demonstrate what's possible using VR-Vantage, and in particular demonstrate that OSG-based code can be easily incorporated into VR-Vantage-based applications. 2) All you need to provide is an executable, plug-in (source code is optional but preferred) or configuration files (with instructions). VR-Vantage runs on both Windows and Linux platforms. Obviously, you also need to include any data that is required for us to run your demo. 3) The contest will be judged by a panel of simulation experts. Entries will be judged based on creativity, visual quality, and on how well they meet our goal of demonstrating what's possible in a VR-Vantage-based application. 4) If there are three or more entries that we decide are compelling enough to use in our marketing efforts, we will pay three prizes: Winner: $1,500 (USD) 2nd place: $1,000 3rd place: $500 The first place winner will also receive a permanent VR-Vantage developer’s license. 5) If we do use your work, we will always give proper attribution. We don't want to take credit for your work! 6) Please make sure that you are only submitting work that you own, or that you have the legal right to distribute. If you want to participate, please visit http://www.mak.com/vrvcontest/ for download links and entry submission instructions. For official rules, see http://www.mak.com/vrvcontest/contest-rules.php Good luck!

Re: [osg-users] Visual Studio 2010 3rd Party
Hi, Way back when I built a package of 3rdParty binaries for my OSG 2.4 installer w/ VS8, I tried to capture all the cookbook steps in scripts. All that info is available at http://osgtoy.svn.sourceforge.net/viewvc/osgtoy/3rdParty/ With general updating of version info, those scripts will hopefully be a big step fwd. My entire build process for OSG on Windows, including binary installer generation using Inno Setup, is also in that repo. cheers -- mew -- Mike Weiblen -- Black Hawk, Colorado USA -- http://mew.cx/ On Thu, Jul 15, 2010 at 9:01 PM, Jason Alexander phishja...@yahoo.com wrote: Hi, I have successfully built OSG with Visual Studio 2010, but my application is still having issues with std libraries when I link in OSG.

Re: [osg-users] Headtracking
Hi,
osgVRPN uses VRPN as the interface to various VR devices, including
trackers. You could use that software stack, or you can extract the
OSG matrix manipulation code from
http://osgtoy.svn.sourceforge.net/viewvc/osgtoy/osgvrpn/

Hi folks
I'm sitting here trying to set up a head tracking...
I got an api that spits out a viewmatrix for the camera and now I have to get
this matrix in the write place.
I wrote an updateCallback for the Cameras (left/right) that looks like this.
class updateCameraPosCallback : public osg::NodeCallback
{
virtual void operator()(osg::Node* node, osg::NodeVisitor* nv)
{
osg::Camera* cam =
dynamic_castosg::Camera* (node);
if(cam)
{
osg::Matrix mat(s-getMatrix().data());
cam-setViewMatrix( mat);
}
}
};
I checked the matrix and it looks ok, but somhow the cameras don't move!
Any tips??
Thank you!
Cheers,
Thomas
