[osg-users] SVN error - access forbidden

Hi, for some days I always get a access to '/svn/osg/!svn/vcc/default' forbidden error when trying to update from trunk with tortoiseSVN. I can access the repo from the browser other repos are working. After some googling I found out that maybe it helps to restart the svn-server? Thank you!

[osg-users] integrating tessellation shaders into osg

Hi all, my goal is to evaluate the usefulness of tessellation shaders for us. We are using a framework around osg so I whould like to use tessellation shaders in osg. I tried my best to introduce tessellation shaders to osg (see diff below) but when running the application the console is

Re: [osg-users] integrating tessellation shaders into osg

Hi Waldemar, I am starting to work on the same integration. I have not tried your code, but was wondering if it is not necessary to use the new Primitive Type 'gl_Patches' in order to use the rendering pipline incl. tesselation steps. Regards Holger -- Read this topic online

Re: [osg-users] Terrain geometry

Hi, VPB isn't really intended for editing terrain, but it generates heightfields that can be dynamically altered at runtime just fine. You just have to be aware that there are multiple LODs of each terrain tile. Could you explain it with more detail? How i can alter heightfield in

[osg-users] OpenSceneGraph 3.0 Beginners' Guide, drawing to a close

Hi all, During the last 6 months, I'm working on an OSG tutorial book named OpenSceneGraph 3.0 Beginners' Guide, with my co-author Dr. Qian Xuelei, and now the hard time is drawing to a close. The book, which is written totally in English, will be published by Packt Publishing in December 2010.

Re: [osg-users] Thinking of adding to the ReaderWriter interface

Wang, I was wondering how you would keep this information resident in the Registry. From your first example it seems like you are setting an option that would attempt to be applied to ALL ReaderWriter transactions, regardless of extension. In this case, some general types of options could be

Re: [osg-users] Thinking of adding to the ReaderWriter interface

Hi Wang Rui, Having a more formal ReaderWriter option control would be a good thing, the current osgDB::Option::OptionString usage is rather overstretched and inflexible. The already exists the Options::PluginStringData which is newer and more flexible but not used extensively, making more use

Re: [osg-users] changing the up direction of the SphericalManiuplator

I've been plowing through this and I can almost get what I need, I just don't entirely understand a couple of things. Is it safe to think of the view matrix as the camera position and orientation? By doing so, I think I understand SphericalManipulator::getMatrix()

Hi all, I've been using point sprites with a small 2-d texture map of a sphere for some time now with great results. I'd like to be able to vary the lighting on my spheres and was hoping that I'd be able to replace the picture of the sphere with a flat disc and use a bump map to affect

Hi Chuck, In the first example I obtained a ReaderWriter object named rwDDS, and then call its setGlobalOption() method. So it actually does the same work with the second example, that is, set the global option for a specified plugin. osgDB::setOptions() can set options for all plugins'

Hi Robert, After a short study, I found that the default option object can work for my present situation, osgDB::Registry::instance()-setOptions(new osgDB::Options(flip_dds)); And reading and writing calls can benifit from it until the global option is set back to default. So I don't think my
