Hi John, Is there a chance to get the presentations/slides/picks/whatever from past year? It would be nice to have it in the osg website. BTW I'm going to post your mail as a community new in the website. Thanks! 2014-05-07 0:47 GMT+02:00 John Richardson richa...@spawar.navy.mil: Greetings

[osg-users] Creating working omnidirectional shadow

Hi, I'm currently working with osgShadow, and it's driving me crazy! I'm really not an expert with shader and so on, but I try to make an omnidirectionnal shadow on my scenes, and I really don't know how to proceed. Every already implement way of making shadow in OSG aren't producing good

[osg-users] Cull callbacks and Geodes

Hi Robert, all, I have an application that will load a model from file and attach a custom cull callback to the node. I recently discovered that my cull callback does not work properly if the root node of the model is a Geode. When encountering a Geode, the CullVisitor will handle the cull

Re: [osg-users] Creating working omnidirectional shadow

Hi Mickael, this is not that that simple as you already found out, but it is achievable with proper use of some of the shadowmaps available. I am using osgShadow::LightSpacePerspectiveShadowMapDB for large paged scenes (this one worked best for me) and it is also based on one light 0 as Jan

Re: [osg-users] RTT Magnifying Glass with multiple zooms

I ended up solving 1 and 2 by using a single texture for the RTT to render the whole window, then setting the drawable's tex coords such that each quad zoomed in on the appropriate area. I haven't decided what to do about the resizing, but it doesn't seem to be stretching the texture (which I

[osg-users] OSG Pick Tex Coords

Is there a quick/convenient way to get the tex-coord for the vertex/drawable returned from an intersection (i.e. the way that osgpick example returns the vertex world and local coordinates)? Or do you have to compute the tex coord yourself? Cheers, Nick -- Read this topic
