Re: [osg-users] bounding box of culled geometry

Hi Wojtek, it looks interesting. I do not have a shadowed scene but I will try it, thanks. Regards, Renzo On 15-Oct-20 2:54 PM, OpenSceneGraph Users wrote: Hi Renzo, You may look

Re: [osg-users] bounding box of culled geometry

Hi Renzo, You may look at osgShadow\MinimalCullBoundsShadowMap.cpp. It scans RenderBins and compute bounds of culled drawables to optimize shadow map resolution. Cheers, Wojtek Lewandowski czw., 15 paź 2020 o 12:40 OpenSceneGraph Users < osg-users@lists.openscenegraph.org> napisał(a): > > Hi

Re: [osg-users] bounding box of culled geometry

Hi Werner, I do not know if I have found the code that you are suggesting. I see that CullVisitor could help to find the near and far plane, however with Z I meant the world vertical axis, not the axis of the view frustum. Regards, Renzo On

Hi Renzo, Maybe a node visitor with z-near and z-far as parameter is a possible approach. Werner On 15. Oktober 2020 09:46:57 MESZ, OpenSceneGraph Users wrote: > >Hi Robert, > >On 14-Oct-20 3:56 PM, OpenSceneGraph Users wrote: > >Hi Renzo, > > >On Wed, 14 Oct 2020 at 12:00, OpenSceneGraph Users
