Re: [osg-users] osgShadow one shot shadow map

Hello Wojtek, ShadowMap::cull invokes culls traversal for both main camera (ShadowReceiving) graph shadow camera (ShadowCasting) graphs. So if you block whole cull on ShadowMap level - it won't draw the scene as well. The trick is to block only the portion that culls ShadowCasting graph.

[osg-users] osgShadow::ShadowMap and _receivesShadowTraversalMask

Hello, I can't find any reference to _receivesShadowTraversalMask in osgShadow/ShadowMap.cpp... Is this supposed to have an effect? We would like it to work as well as _castsShadowTraversalMask. A workaround would be to add the node to a different subgraph than the shadowedScene, but is there

Re: [osg-users] osgShadow::ShadowMap and _receivesShadowTraversalMask

Hello Paul, _receivesShadowTraversalMask and _castsShadowTraversalMask are available in ShadowedScene so that any ShadowTechnique can use them if necessary, but as far as I know there is no requirement for any given ShadowTechnique to use them. Yes, that's my point. It seems that in the case

Hello Andreas, have you run the project with OSG_NOTIFY_LEVEL=debug? There you can see, if your shader-program is faulty. Thanks for the tip, we're making progress here. When running my program with OSG_NOTIFY_LEVEL=DEBUG, I can see that the shader is never even compiled! If I do the same

Hello Raymond, Can you try to use a ref pointer instead of the regular pointer for osg::Shader* shader. I believe I encountered exactly this issue when working on the PSSM, please see a patch that I sent +/- a week ago. It has no effect, and anyways, it would not have explained why

[osg-users] osgShadow::ShadowMap not reacting to changes

Hello, I am using osgShadow::ShadowMap. Shadows show up fine, but I am trying to change shaders on it, and it doesn't react to my changes. I've even added this code to try some things out, in my frame loop: static int f = 0; if (f == 200)// After 200 frames {

Hi J-S, Can you try to use a ref pointer instead of the regular pointer for osg::Shader* shader. I believe I encountered exactly this issue when working on the PSSM, please see a patch that I sent +/- a week ago. The shader was not cleaned up in the case of PSSM, and hence the new one was not

Hi Mihai, I'm currently very busy, so only skimming osg-users, and as a consequence finding it difficult to dive into complex topics. General comments: osgShadow is still in its infancy so comments/suggestions for improvements are very welcome. Support for perspective shadow maps is

[osg-users] osgShadow::ShadowMap adding some polish

Hi Robert, I'm working now on integrating the new osgViewer and osg 2.x into the simulator of our company, and as a result I am moving to using osgShadow::ShadowMap in place of the old code that I refactored to use with osg 1.2, before the first iterations of the NodeKit. I will extend the osg

[osg-users] osgShadow SoftShadowMap

Hello I have adapted to osgShadow the soft shadow map technique described in Efficient Soft-Edged Shadows Using Pixel Shader Branching by Yury Uralsky, Chapter 17 of GPU Gems 2 (Matt Pharr ed. Addison-Wesley). I have tested it under Linux with a NVidia graphic card, but there should be no
