[osg-users] Using NodeMask...

Hi, I am working on a hide/show function, and I've read some examples concerning NodeMask. It looks like a good and easy solution to do that, but I don't understand why it doesn't work on my application : int inheritanceMask = (osg::CullSettings::ALL_VARIABLES & ~osg::CullS

Re: [osg-users] Using NodeMask...

"toggle the earthGroup NodeMask between 0 and 0x." it is not what i done here : ? earthGroup->setNodeMask(0x1); Is my code good concerning the camera ? is it a viewer parameter ? (to set cullMask) I preferer avoid using switch node for the moment, it would add nodes to the graph, and if

Re: [osg-users] Camera and light problem

Hi Jon If you add your transform to the camera, it is normal that the light follow the camera.. If you want to keep the light at the same position, you have to attach it near the root node, and attach the rest of the scene a lower levels than it. Each child inherit from its parents, so if you at

Re: [osg-users] obj normals

Hi , I don't know if an easy way exist, but you can get your normalArray and "correct" it... but you have to know exactly the vertices number to get normal and invert it... Vincent. 2008/3/7, lorenzo bronzin <[EMAIL PROTECTED]>: > > hi robert, > > > loading a wavefront .obj file is there a wa

[osg-users] osgFX::Cartoon (setOutlineLineWidth)

Hi, I'm using osgFX::Cartoon to obtain an effect on the edges. I want to highlight edges of a node. (geode) I've already tried osgFX::Scribe, but I prefere Cartoon edges because it compute only the necessary edges and not all. So, my problem is when I use Cartoon, I can't set LineWidth. I can pu

Re: [osg-users] Camera and light problem

Hi Jon, If your light is in the model at (0,0,0) it is normal, because in the graph, the position is always relative (depends on the parent node) (if you let it by default). try something like : -ROOT ---lightsource ---tranform --geode In this case light source will be in relative coordinat

Re: [osg-users] Stopping a particle system after a set number of particles

Hi, I think it doesn't exist yet... (perhaps I make a mistake writing this)... But counting time left before stoping the particlesystem is not very difficult... just make a time difference and switch off your particleSystem (or remove it) from the graph... Vincent. 2008/3/11, Kim C Bale <[EMAIL

[osg-users] Render a node through the other

Hi, I work on complex models, and I use the osgFX to put in relief some nodes. However, I am asking myself if it is possible to render a node through the others ... ? What I would like to obtain, is to see a node (geode) in relief (with osgFX) through the hole model (and so through the other geode

Images folder have to be download in the DATA dependencies... and after that you'd better add a environnement variable (look on osg site web) Vincent. 2008/3/12, Bryan Berg <[EMAIL PROTECTED]>: > > Hi guys, > > So I'm playing with the example osg apps, but I don't seem to have an > Images > folde

Re: [osg-users] Assertion failure - using removeChild

Hi, Have you checked all the variables ? I have encountered the problem because my Node was not good... sometimes you get an error but it is another bug in your code... Try to verify each variable (in debug mode for example (step-by-step)) and you'll find your problem. I don't think it is an OSG
