[osg-users] Rubber band selection for pixel masking

Hi all, I'm trying to implement a rubber band selection tool (and also a polygonal selection tool), and I'm wondering which is best approach since there are a number of options in OSG and it's a bit confusing... Note that I don't really need the PolytopeIntersector, because I need to create a bit m

Re: [osg-users] OpenSceneGraph performance drop between Qt 4.7 and 4.8

I've even disabled the vsync but it does not improve the frame rate. You can verify this just by running osgViewerQt right away. Marco ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-ope

[osg-users] OpenSceneGraph performance drop between Qt 4.7 and 4.8

I'm working with OpenSceneGraph 3.0.1 (the latest stable) and Qt. I have noticed a strange frame rate drop switching from Qt 4.7 to 4.8. With 4.7.3, the frame rate was maximum 60fps on every computer. With 4.8 the frame is maximum 38-40fps on every computer. Definitely too much to accept. I cannot

[osg-users] Offscreen viewer maximum resolution problem

Hi, I need to render an offscreen image with a resolution of 2048x2048, and I'm sure that the graphics card can do that because the max framebuffer size is 8192x8192. I'm doing that by using a newly instanced CompositeViewer with Qt and by calling once frame(), then a screenshot callback captures t

[osg-users] OSG 3.0.1 on MacOSX 10.7 release issues

Hi, I'm trying to compile OSG 3.0.1 on MacOSX Lion (10.7). I got errors at compile time due to changes in some framework API. But I haven't got any error if I define CMAKE_OSX_SYSROOT=/Developer/SDKs/MacOSX10.6.sdk If I compile using Makefiles and also define CMAKE_BUILD_TYPE=Debug CMAKE_OSX_A

Re: [osg-users] 3.0 or 2.10?

Hi all,as an example of a concrete project for shaping OSG 3.0 I suggest developing a ray tracing backend for meshes and point clouds (not only volume rendering), probably using OpenCL. Is there anyone else interested in this? Marco ___ osg-users mailing

[osg-users] Saving big frames

Hi all, I want to save in a file a rendering with a resolution that could exceed the screen resolution. I guess that I have to tile it in a way similar to the osgwindows example, but then i have to combine the tiles in one big image to save. Is there something already done to do this fusion? Thank

[osg-users] Ray tracing

Hi all, have you ever considered the possibility to support ray tracing rendering as an alternative to OpenGL? Is there already someone playing with this? Real time ray tracing is becoming a reality and it seems that in the incoming years it will be the new trend. It is a naturally parallel algori
