Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hi Nick, I failed to use the default Shadow-Mapping techniques in a deferred rendering context. I never fully understood how to split the shadow-map generation into later binding the resulting texture to my actual lighting/shadowmapping part. Any insights on this? Basically I've got

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hi Sebastian, I am not DR expert ( I am reading now some papers though ). Marcin Hajder or Wojtek Lewandowski for sure can answer this. Hope they will give you some insights. Sorry :-) .. If my learning goes well, in few months I will revisit this topic ;-) Nick On Mon, Jun 8, 2015 at 9:03 PM,

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hi Werner, I am not the author of the LISPSM technique (Wojtek Lewandowski is), but if it all works for GL2 (which I use too) I expect it is something with the GL3 support. And yes, the shadow technique has it's own shaders you can replace too (what I am doing for my project). Have a look at

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Sorry, was on a business trip for a while. Here is my code (shortened a little): osg::Group*rootNode=newosg::Group(); view-setSceneData(rootNode); shadowedScene=newosgShadow::ShadowedScene; shadowedScene-setReceivesShadowTraversalMask(ReceivesShadowTraversalMask);

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hi Werner, I am doing the same and using the LightSpacePerspective shadow techinque. In your program you have to set your vertex and fragment shaders as well, and it will be picked up correctly if you set the masks for receiving/cast shadows So it should work. As long as they are part of the

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hi Nick, I'm using LightSpacePerspective shadow technique as well. But I set the shaders only inside the scene graph where reqired. Do I have to set them anywhere else? My graph looks like that: *--- * | RootNode | *

[osg-users] How does shadow technic work if geometry shaders are in use

Hi all, My scene contains many objects, which are created by geometry shaders. So no vertices are created outside the graphics card for those objects. So I use state-setUseVertexAttributeAliasing(true) and state-setUseModelViewAndProjectionUniforms(true) Is it possible using a shadow

Re: [osg-users] How does shadow technic work if geometry shaders are in use

Hard to say without seeing your code I have modified shaders for the LSPSM. Can you share a sample app ? On Fri, May 29, 2015 at 6:38 PM, Werner Modenbach werner.modenb...@texion.eu wrote: Hi Nick, I'm using LightSpacePerspective shadow technique as well. But I set the shaders only
