Re: [osg-users] [vpb] Building VPB

I'll answer my own post - found the fix in another post, ( being only my second post, I'm unable to put a link here...) I can now generate nice terrain easily ! -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=43955#43955 __

Re: [osg-users] osgText and GLES2

Any takers ;) I should be able to implement any fix needed, just need a bit of guidance as I'm not too familiar with the internals of osgText. Thanks Tom -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=43953#43953

Wait a sec I think I spoke too soon. I used [/code]osg::Matrixd transformMatrix = osg::computeLocalToWorld(this->getNodePath(),true); Code: to create a transform matrix to go from local to world coordinates, but what does world coordinates mean in this case? What if I've read in my ive terr

Re: [osg-users] [osgPPU] FIX: osgPPU rendering not working in the first frame

Hi Alex, ok, this is of course pretty bad. Actually, I think the correct way would be to apply the texture to the osg::State within the FBO::apply(). This would ensure that the state is tracked correctly. Of course, unfortunately this requires a patch to the main osg core. In general, I thi

[osg-users] OsgParticles one frame latency ?

Hi, I'm using osgParticles to make a smoke trail on a node moving very fast in the scene. It seems particles have one frame latency so that the starting point of the trail is late on the trajectory compared to the moving node. Is it something due to particles architecture ? How to avoid this be

Re: [osg-users] [osgPPU] FIX: osgPPU rendering not working in the first frame

Hello Art, glPushAttrib / glPopAttrib works as well, but it's not available in GLES and I also use osgPPU with GLES. However in GLES there are no 3D textures, only 2D and cube maps. Regards, --Alex -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=

Re: [osg-users] update callback with multiple node path

Hi, The update callback is done to be updated each frame in the traverse() method. Rewriting it is necessary to update it. So add a callback on the decorator and update it in traverse() method. Regards, Vincent Le 18/11/2011 09:39, xbee a écrit : Hi all, I'm trying to make "blinking" a part

[osg-users] update callback with multiple node path

Hi all, I'm trying to make "blinking" a part of my scene by adding a "decorator" node (a group node with a shader) like this: Original graph root | _ _ | | node1 node2 "decorated" graph root | _ _ _ | | | deco | node2
