Re: [osg-users] Text Intersecting Earth

Hi Jeffrey, In the 2.x series of the OSG there is an osgfadetext example that uses a ClusterCullingCallback to cull the text when its on the far side of the earth, and disables depth test when its on the front side - this sounds similar to your needs. Robert. On 10/16/07, Jeffrey M Short [EMAIL

Hi and thanks for the tip about where to look for code for the projectionOffset. I now have a slave camera with the expected projection offset next to the master camera. One thing that I found out was that the slave camera is drawn one frame after the master. Both cameras are drawn to the same

Hi Will, The quaternion multiplication order has to be consistent with the rest of the OSG i.e. v' = v * M; Now what is standard for other libraries, or even other communities is an issue, but since libraries and communities all use their own standards there is now way for the OSG to be

Hi Karl, The master and slave cameras will be drawn in the same frame. If you see a difference then it must be down to the propagation of the settings from the master to the slave being out of sync. I don't know how you set the master, perhaps you are setting it after the sync point. The
