Re: [osg-users] Creating holes in a PagedLOD

Hi John, VPB itself doesn't support cutting out of holes. You will need to post process the tiles to insert these. If you have built the database with osgTerrain::TerrainTile (this is now the default) you will have to think about writing your own TerrainTechnique for converting the tiles height

Re: [osg-users] PBOs and stutterless texture uploading

Hi Eduard, The use of PBO may well help, but only if the pixel formats are accelerated properly by the driver, this can be a bit of lottery. It just so happens that my recent work on integrating GLU implementations directly into the core OSG has been prompted by the wish to pre-process imagery

Hi Everyone, Big Thanks to Farshid for the solution :-) Support for his workaround, to use Copy as a swap Method, was recently included in OSG trunk. SwapCopy is not active by default - people not using Aero should be still happy with default SwapExchange. These who would like to activate

Re: [osg-users] GLU integration

Hi All, I have now moved the subset of glu functions that are now part of the core OSG library into the osg namespace, so the likes of gluScaleImage now would be used osg::gluScaleImage. I have also introduced a gluScaleImage version that doesn't use glGet's, instead you pass in a

Re: [osg-users] render a node last

You can use a Camera post draw callback (setPostDrawCallback) or you can use render bins (setRenderBinDetails). Search the newsgroup or OSG source for more info. You might also need to deal with the depth buffer. -Paul On 10/7/2010 10:22 AM, lucie lemonnier wrote: Hi, How to render a

Re: [osg-users] OSG seems to have a problem scaling to multiple windows on multiple graphics cards

Hi John, This is odd but it sounds bit like swap buffers of the windows are somehow waiting for each other. I believe that WGL_NV_swap_group extension is not used by OSG. This extension could possible help you there. But I could be wrong on above. It is not really my main point I wanted to

Re: [osg-users] OSG seems to have a problem scaling to multiple windows on multiple graphics cards

Hi, Many thanks for your speedy reply. We were considering trying mosaic mode if we couldn't come up with something that would fix the problem with our current display configuration. Switching to mosaic mode will require a good bit of code rewrite, but if that's the way to go I guess it's
