Hi Sanat, I use Vista 64 as well so it shouldn't be a problem. You can set the OSG_NOTIFY_LEVEL=DEBUG environment variable and see where it is trying to load the plugins from, it should shed some light on the issue. Thanks, Jason On Fri, May 7, 2010 at 2:45 PM, Sanat Talmaki wrote: > Hi Jason

Hi Jason, Im using Vista 64 bit. (But my visual studio is installed in program files x86) Could my OS be the reason why things aren't working like the are supposed to ? In that case I will need to build all the dependancies from source ?? Thanks Sanat -- Read this topic online

Re: [osg-users] osgGA/SphericalManipulator : Cannot open include file

Hi Sanat, You have to make sure that you built osgEarth against that version of OSG, GDAL and Expat and make sure all the Dlls (osg, expat, GDAL, osgEarth, and the osg 3rdParty dependencies bin for png, jpeg, etc) are all in your PATH. Jason On Fri, May 7, 2010 at 12:22 PM, Sanat Talmaki wrote:

Hi Paul, sorry last question about your courteous answer. Continuing with the analysis and study of the OSG code now it's clearer to me what you meant about feauters that are recognized in FLT plugin. Now I've understood that FLT plugin is only mapped with OSG objects so an OSG file written w

Re: [osg-users] OFF file format

Don't think .off is used very much anymore (if it wever was) It's pretty simple to write a new file format writer (reader is trickier) Just start from the .obj source, post any questions you have here. Cheers, Martin -- Read this topic online here: http://forum.openscenegraph.or

Re: [osg-users] Transparent Camera Clear Color isn't Working for Me

Hi, Thanks for the quick response guys. @Simon: Turns out that there was a bug in my OSG Window implementation. (As you said there is no x-platform method of ensuring a transparent window / view) @He: No I'm actually attempting to render my OSG scene atop a preexisting OS window. Now that

Re: [osg-users] Transparent Camera Clear Color isn't Working for Me

Hi, Colin, Are you trying to draw a scene on top of another scene, but want no background for the scene on top so that you can still see the content of the scene in the back? I haven't followed up on the recent development of OSG (still using a version from 2006 with Producer), but in my c

Hi D.J., Then again, I could be totally off base, so feel free to correct me, and I'll be happy to learn from the experience. :) Nope, I think you're totally right, as I said I needed to find a case where the current behavior was desirable and you certainly gave a good one. Adding a bool t

[osg-users] small memory leak in SceneCache?

Hi all, being my first post i hope i comply with all mailing/forum rules. By setting up a unit test where the osgViewer::Viewer is used i observed the heap increases a few bytes each time the viewer is instantiated and destroyed. I tracked it down to s_sceneCache in osgViewer/Scene.cpp: Since Re

[osg-users] OBJ export of Shapes, any progress or workarounds?

Hi, I have read some older threads "why aren't shapes appearing in obj files". I understand the problem, but for inexperienced OSG users like myself it is quite hard to improve OBJ exporter to capture the triangles that are used to draw ShapeDrawables. Has anyone written some code that solves

Re: [osg-users] Limitation of NodeMask

Seems like at least I have started an interesting discussion here! Really, I only used PICKABLE and VISIBLE as an example-probably not the best because pickability and visibility are logically somewhat entwined. It would be better to see the mask as a set of (32) independent logical flags. Th

[osg-users] OFF file format

Hi, Does OSG support "Object File Format" (off (http://www.holmes3d.net/graphics/offfiles/offdesc.txt))? It is very similar to Wavefront OBJ. Thank you! Cheers, Dženan -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=27661#27661

Re: [osg-users] Limitation of NodeMask

J-S, If I follow the code and this thread correctly, I don't think this a bug; I think it's a limitation of the current implementation. For example... If I have nodes masked by type (Craft, Planet, Debris, etc), and I only want to pick nodes of certain types (Craft and Planet, but NOT Debris), t

Hi Sanat, Unfortunately, I do all of my work on Linux. You should be able to install all the osgEarth libraries (dlls) to the osg-plugins directory. I thought one of the options when building osgEarth was to have it install to the osg directory, but again I only do it on Linux. Also, yes, it

Re: [osg-users] Limitation of NodeMask

Hi Simon, Yes, he wants to only pick objects which are pickable AND visible. Which you can't do just using a node mask, you'll get anything which is pickable OR visible. That's a bug IMHO. If I say this: int VISIBLE_MASK = 0x01; int PICKABLE_MASK = 0x02; // Render only what's visible view->g
