Hi JP, is it possible to let OSG render a bunch of FBO cameras without the main camera rendering and calling swapbuffers? If so, how do I disable the main camera for a few OSG frame() calls? You can have a whole bunch of prerender RTT cameras in you scene graph, and they will all render befo

Re: [osg-users] [osgPlugins] Problems creating MSVC project files for png plugin using CMake

Hi Jason, Right now I am experiencing some troubles generating the project for the png plugin -- I downloaded the 3rdparty package which seems to contain all necessary libraries, also I set the variables ACTUAL_3RDPARTY_DIR, PNG_INCLUDE_DIR, PNG_LIBRARY and PNG_LIBRARY_DIR, but CMake just quietly

Re: [osg-users] 3D model database

Hi Jason, Bruce, You should be able to get these numbers by iterating over the primitive sets in each drawable. You'll have to count differently depending on primitive type and primitive set type, but it's not that difficult (there may already be a visitor in OSG that does this, I'm not sure)

[osg-users] Ann: osgBoostPython

Hi all, I'd like to announce the initial availability of osgBoostPython, a very work-in-progress python wrapping of OSG. The project is on Google Code here: http://code.google.com/p/osgboostpython/ Seeing how osgSwig had its problems wrapping recent versions of OSG, and wanting to do somethi

Re: [osg-users] FBO OpenGL Error with new nVidia Driver

Hi Sebastien, Also please remember that NVidia have systems for logging bugs, and fixing them, so go chase them about it. Yes Robert is right, if you've found a possible driver bug (even if it's only specific to one series of cards) then you can report it and they will probably fix it. In th

Re: [osg-users] Ann: osgBoostPython

Hi Martin, I'm glad someone is interested in this. :-) I like your approach. The python interface has a good pythonic feeling, subclassing NodeVisitor works fine and building up geometry does also work fine! I'm definitely going to contribute to this. Great! I'm still working out how to do

Re: [osg-users] Render FBOs with main camera disabled - possible?

Hi JP, thanks, it seems to work. Attached a simple test app modified from osgscreencapture. If with vsync on (60Hz) I render one pbo and then 1 normal, the stats report 120fps, 2 pbo and 1 normal gives 180fps... Excellent, good to know it worked out. J-S -- __

Re: [osg-users] OSG Threading

Hi Prasad, I do not have a loop but I will call display() when ever is required. When I wrote only viewer.frame() as soon as it come out of display() the osgwindow(scene) is closing. Well of course if your viewer instance goes out of scope at the end of display(), the viewer will close.

Re: [osg-users] Ann: osgBoostPython

Hi Gerwin, Great effort! It will be interesting to look at the way the Boost wrappings behave, especially when compared to our osgswig stuff. Yes, I think so too. Glad to see you're not seeing this as a competition, I was a bit nervous as to how you'd react since you've been doing this for a
