Re: [osg-users] OSG dotNet wrapper for osg 3.1.1 version
Hi Vishwa, I think OSGDotNet is not maintained anymore. But it is very straightforward to include a form for OSG rendering within a C# application. You'll need to create C++/CLI project for your 3D visualisation, an example of this can be found in the attachments at the bottom of this page http://www.openscenegraph.org/projects/osg/wiki/Community/LanguageWrappers (OSGCppCLIDemo.rar). Add a reference to this C++/CLI project in your C# GUI project, next you can create the C++/CLI windows form in C# code.

Re: [osg-users] VBO Bug ?
Dear Wojtek et al., This mail reminded me of an issue I had a couple of years ago with VBO's on a particular Windows pc with a 9800GX2. I thought it was an issue of that PC, as it was quite unstable, so I didn't report the problem at that time. The solution I accidently found back then was to turn off Threaded Optimization in the NVidia Control Panel (Auto per default). But now I'm getting the bad result of your test on a GTX 480 (266.58 driver), and that fix works again. After turning off Threaded Optimization, I see the proper gradient displayed.

Re: [osg-users] [Need Help] Entire 3d environment needs to be bump mapped.
Dear Zach, The older post are right. For bump-mapping, you'll need two things: a bump mapping shader and a normal map texture for each of the objects you'd like to bump map (assigned to a different texture unit than your diffuse texture, e.g. unit 1). The good thing of the scene graph concept is that you create a hierarchy of objects. If every object in your scene indeed has a bump map texture assigned to it, you can just attach your bump map shader to the state set of the root (i.e. topmost) node of your scenegraph. Objects in the hierarchy will inherit this shader. The same goes for the required uniforms (e.g. the uniform that maps the texture2D sampler name in your shader to the OpenGL texture unit the bump is assigned to). Hope that helps, Ruben From: osg-users-boun...@lists.openscenegraph.org [osg-users-boun...@lists.openscenegraph.org] on behalf of Zach Lenker [zach.len...@vrsim.net] Sent: Thursday, July 14, 2011 12:12 AM To: osg-users@lists.openscenegraph.org Subject: [osg-users] [Need Help] Entire 3d environment needs to be bump mapped. Hi, The subject sums up what my basic goal is. We have a 3D environment that has roughly 50+ objects inside of it. Each object needs to have bump mapping applied to it. My confusion comes in at the part where we are applying the bump mapping to each object though OSG. I have done a few hours of searching these forums and Google and haven't really found anything concrete to go on. Anything that I found relating to this issue was a year old (or more). Those posts were saying that in OSG I would have to write a bump mapping shader and apply it to the model. Those posts also seemed to be targeted toward getting a single (or a few) object(s) to be bump mapped. Is that still the only approach? If so how do I go about applying the bump shader to each individual object within the single environment file? Currently using OSG 2.6, we are not bound to any file type constraints (we are currently using .IVE for the environment file). I tried my best to put any information that would be needed, but if you need more information or more clarity, please let me know. Thank you!

Re: [osg-users] OSG in C# environment
Hi Saeed, Yes, it can be done quite easily. I've been using OSG in combination with C# / WinForms for years now. The way to go is to start with the example created by Hesicong (http://www.openscenegraph.org/projects/osg/wiki/Community/LanguageWrappers, see the attached osgCppCLIDemo.rar). In this example, you use a C++/CLI project to interface with OSG and a Form to provide the rendering area. Your C# projects can include this C++ project and the Form automagically. This works great for creating an editor / 3D modelling tool. If you have any specific questions, let me know.

Re: [osg-users] Create a simple river
Dear Daniele, I don't think Bruneton's research, although very impressive, is the simplest way to render a river :-) The simplest way I see is to create the OSG geometry for this river with some code. You would have to segment your curve/spline into small quad sections, use a tiling texture and let the u-coords go from 0 to width_of_river / texture_scale in the lateral direction and the v-coords along the curve itself from 0 to total_length_of_river / texture_scale. As the texture is tiling, you can scroll it along the river in a fragment shader, where you add time-dependant amount to the v-coord before the texture lookup. You can use osg_SimulationTime for this. If you're using Bezier curves, you might want to look at this http://graphics.tudelft.nl/~ruben/PosterI3D2010.pdf, a student of mine did work on rendering Bezier-curve based river networks, as an extension of osgOcean.

[osg-users] [osgOcean] Member var initialization bug in Cylinder
Dear all,
Here is a simple fix for an error in the Cylinder class of the current svn
trunk version of osgOcean. Yesterday's revision 156 introduced member vars for
the Cylinder (_radius, _steps, etc.) but these were not initialized in the
Cylinder constructor, resulting in uninitialized vars being passed to the
build() method, resulting in a bad_alloc crash :-)

Re: [osg-users] [OT] Looking for a lib that adapts terrain to 3D object
Hi Sukender, That depends, really. If you just want to flatten terrain around building footprints and these buildings are located not too close to each other, you can flatten the heightmap within the footprint to, for instance, the average elevation (or perhaps the elevation value is given for that building, by some measurement or property). To avoid sharp changes in elevation you can blend in a transition area around the building footprint, interpolating between the original heightmap value and the building footprint value. It can become tricky and problematic when you have lots of different types of features (buildings, roads, rivers), located close to each other, as the height modifications may start to interfere with each other. This paper might be interesting for you (more focused on road blending though): http://www-evasion.imag.fr/Publications/2008/BN08/ Kind regards, Ruben -Original Message- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of suky0...@free.fr Sent: donderdag 30 juli 2009 14:23 To: OpenSceneGraph Users Subject: Re: [osg-users] [OT] Looking for a lib that adapts terrain to 3D object Ok.

Re: [osg-users] Windows forms and c#
Hi Ba, I don't think there's an incompatibility between the OSGViewer .NET Control example and OSG 2.8.1. For instance, I'm using it with OSG 2.8.0. The error could just be as simple that the OSG .dll's are not found when launching the app. * Did you compile the Debug version of OSG 2.8.1? (This would result in dll's with the -d suffix) * Are your environment vars set? Especially the OSG_BIN_PATH, add it to your PATH as well: http://www.openscenegraph.org/projects/osg/wiki/Support/PlatformSpecific s/VisualStudio * Did you debug run the application from within Visual Studio? You can also use depends.exe to check for missing dll's for your app. Hope this helps a bit, Ruben From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of buidinhba5 Sent: woensdag 24 juni 2009 5:14 To: 'OpenSceneGraph Users' Subject: Re: [osg-users] Windows forms and c# Hi All I have download osgNETDemo.rar from http://www.april1985.com/2008/02/19/osgnetdemo/#more-322 Download link : http://www.april1985.com/?dl_id=7 I Use OSG 2.8.1 , and in VSProj , in project I add /Lib and /include of OSG 2.8.1 In VS 2005 In debug mode I compile success but when I run it get error ; The application failed to initialize properly (0xc015002).

Hi Paul, Nice, I think that would be interesting. It would make it far easier for .NET developers to choose to use OSG for their 3D rendering.

Re: [osg-users] OSG .NET demo using C++/CLI / again
Hi Ernest, Good to hear that you have your program running now. I can't really guess what you did to fix it. I'm using C++/CLI with OpenSceneGraph as well (also started from Hesicong's great example) and the SEHexception that you encountered in my case was that either an OpenSceneGraph .dll was not found (check the environment vars for the OSG_BIN_PATH and if the OSG_BIN_PATH is in your PATH var) or that the OpenSceneGraph .dll's were build in Release mode, while my C++/CLI program was build in Debug mode (or the other way around of course).

Eventually, the program compile and ran correctly. I changed from Debug to Release mode as well. Still don't understand what I did to make it work. Any help on how I managed to fix the problem would be appreciated.
