Re: [osg-users] Visibility of lines

Hi, I think there might be a small bug in osg::OcclusionQueryNode, that I've yet to find. Here is a small example with a line triangle, that shows the problem. I added no face geometry so the lines should basically always be visible when in view. Each line is under an OcclusionQueryNode, but

Re: [osg-users] [vpb] osgdem: set texture minfilter and magfilter to nearest?

I took the coward's way out before and manually changed the min and mag filter settings in the VPB src to accomplish this task. This worked in a pinch but I'd like to get back on the VPB trunk and learn how to do this the right way. Any advise on how to search an entire PagedLOD terrain

Re: [osg-users] Change Camera FBO attachment

Hi Riccardo, Setting up the camera's rendering backend on each frame will be expensive. Personally I'd just using multiple RTT Camera each with their own FBO and Textures associated with them. Using a Switch, Sequence or NodeMask's you can select which of the Camera you want to render to on each

[osg-users] [osgPPU] Objects not released

Hi all I'm trying to track down some memory leaks in my application which uses osgPPU. I noticed a difference between the following two methods of cascading units: - When I cascade units through childUnit-setInputToUniform(parentUnit, ...), then the units seem to have a object reference that
