[osg-users] Example of osgPartilcle::ExplosionOperator

Does anyone have an example on how to use the osgPartilcle::ExplosionOperator class? I have tried to modify the osgshaderparticle example to include this but I can't work out how all the parameters are used. I have tried to look at http://www.particlesystems.org but it appears to be no longer

Hi Mathieu, Here is a summary of what I did to get it to compile in MSVC 2015. at line 130 where is says SET(OPENSCENEGRAPH_SOVERSION 145) add the following lines that set the version numbers SET(OPENSCENEGRAPH_MAJOR_VERSION 3) SET(OPENSCENEGRAPH_MINOR_VERSION 5)

Re: [osg-users] Insersector doesn't take into account DrawableCullCallback result

Hi Davide, to addition to Robert - the way how I resolved similar case in the past was indeed by having the NodeMask only on/off (0x0/0x) and in combination with osg::Node::setUserValue where I was holding my ids (here you can put your layer id for example) I was able to make the

Re: [osg-users] Fwd: OSG performance measurement

Hi Hannes, There really isn't much info to go on from what you are written so far. Using the StatsHandler is a good first step but just the frame rate reports doesn't tell us enough to know what is going on. Try toggling the the high levels of stats info and then look at the size of the update,

[osg-users] Fwd: OSG performance measurement

OK. Scratch that, I no longer believe that this is a performance measurement issue, but rather a performance issue. I have replaced my measurement code with the built in StatsHandler class, so my code now looks as follows: int main() { ref_ptr viewer=new osgViewer::CompositeViewer(); ref_ptr

Hi Robert, thanks for your quick reply. If I have well understood, the NameMask allow to define up to 32 masks (32 bit). My problem is that I have an unpredictable number of layers (in general more than 32): this is the reason why I have used DrawableCullCallback. As an alternative you suggest

[osg-users] OSG performance measurement

Hi all New to OSG so apologies if this is a stupid question. I have written a visualization tool in OSG and as a last step, I wish to ensure that it runs at the screen refresh rate. My perception was that it mostly runs smoothly but stutters every few frames or so, so I wrote code to print the

Re: [osg-users] Insersector doesn't take into account DrawableCullCallback result

Hi Davide, The Intersectors don't have specific handling of drawable callbacks so I don't think it'll be possible to do it how you want. Personally I wouldn't use DrawableCullCalbacks to toggle on/off drawables from rendering. I'd either use a osg::Switch or a NodeMask that decorates the

Hi Uma, The stack trace you have provide doesn't really give us any clues to what might be amiss. Form the OT version it's clear you use a dev version of the OSG/OT, there is chance that there is bug lurking in the recent OT changes. I would have expected this to be to appear in the debug
