Hi CG, you can maybe have a look at the osggis project http://wush.net/trac/osggis It does this quite well. I've used it for tracing the river aver the terrain for example... http://perso.imerir.com/bourdin/wiki/doku.php/en/projet/massane Hope it helps, Pierre. Le jeudi 02 juillet 2009 à

[osg-users] OSG_USE_UTF8_FILENAME

Hi all, I just recompil osg with the OSG_USE_UTF8_FILENAME option, but I didn't saw it in the readNodeFile code. So even if I can open a file with UTF8, a nodeFile with a path containing special caracters is not found... Is there any reason or is it something which have been forgotten ? And a

Re: [osg-users] osgDB::fileExists returns false with path containing accent

Hi Vincent, Any idea ? I'm looking for hours without results... Looking into 'osgDB::fileExists' the envvar 'OSG_USE_UTF8_FILENAME' should only be relevant for windows, because the windows specific function '_waccess' is called. In the other case 'access' is called. Which should mean, that

Re: [osg-users] osgDB::fileExists returns false with path containing accent

Hi Vincent, I'm not linux major, but if I understand you, the Linux user have to use UTF8 himself instead of the windows user which can assume that osg will manage the UTF8 conversion for him? If you mean by himself, that the user has to set the locale for the application accurately if the

Hi Robert, sorry for my late reply, but your posting didn't make it to the gmane newsgroup which I am using. So I'll give the forum a try :-) I didn't modify the OSG code because we're using various installations here (windows and linux). The WindowManager has a memeber EventInterface*

Re: [osg-users] osgManipulator refactored

Hi Robert, This is good news! I've just been experimenting osgManipulator for the purpose of integrating it into our application. However, I had a big issue with the fact that draggers only could update Selection nodes. Thanks for changing this. I particularily like that it's now possible

[osg-users] projective texturing

Hello, I try projective texturing and I didn't use the TexGen. Also I use a shader. And in the vertex shader I do this: gl_TexCoord[1] = ( projMat * viewMat * gl_Vertex ); gl_TexCoord[1].s = gl_TexCoord[1].s / gl_TexCoord[1].q / 2 + 0.5; gl_TexCoord[1].t = gl_TexCoord[1].t / gl_TexCoord[1].q / 2

Re: [osg-users] osgManipulator refactored

Hi Robert, So this week I rather than just hack a bit of extensibility into Dragger to allow me to observer changes to the Dragger, I took the opportunity to refactor osgManipulator to make it simpler to use, more encapsulated, easier to use with conventional nodes and more extensible. These

Hi Simon, I've run into that same issue with osgWidget. I was removing a widget when the user clicked on it, and osgWidget was trying to send a mouse up event to the newly deleted widget. I ended up just keeping the widgets around in a higher level manager class so they would still exist, but I

HI Ernesto, .vym files are View Your Mind mind maps - it a cross platform, open source app, so go browse the web for a binary. .p3d files are Present3D presentation file, Present3D is OSG based application that now part of the core OpenSceneGraph distribution, you'll find it in the 2.9.x series

Re: [osg-users] projective texturing

Hello, I have the answer of my question. My mistake was that the lines... gl_TexCoord[1].s = gl_TexCoord[1].s / gl_TexCoord[1].q / 2 + 0.5; gl_TexCoord[1].t = gl_TexCoord[1].t / gl_TexCoord[1].q / 2 + 0.5; ...musst into the fragment shader. Cheers, Martin Am Donnerstag, den 02.07.2009, 15:19

Re: [osg-users] thousands spheres renedering with OSG

Perhaps i'm fooling but... Disabling culling may help? If your bottleneck is culling, perhaps the GPU would eat them all without problems. Of course you will render a lot of geometry you will not see, but you will avoid a lot of CPU computation. Fast and dirty test. If you are not happy, then you

Re: [osg-users] osgVolume issue

Hi Jason, This is a missing feature rather than a bug - with GLSL you have to implement everything yourself, and one can't second guess all different combinations of usage that users might wish to use. In the case of clip planes, they simply aren't support by the current rev of
