Re: [osg-users] Shadows and negative renderbin?

Hi all, I just wanted to mention for the sake of closing this thread, that the problem was caused by the shadows and the skydome both having a texgen state on the same texture unit. This caused two things I could observe: 1. No shadows at all when the skydome's renderbin was set to a negative

Re: [osg-users] Shadows and negative renderbin?

Hi Wojtek, Look inside the MinimalShadowMap::ViewData::computeShadowReceiveingCoarseBounds method. ComputeBoundingBox visitor has node mask set to cast shadow bitmask before visitor is run on ShadowedScene graph. I did not mean more than this. Hmmm, changing it to use the ReceivesShadow mask d

Re: [osg-users] Shadows and negative renderbin?

Hi Again, That looks like the problem with boundingBoxVisitor called inside MinimalShadowMap::ViewData::computeShadowReceiveingCoarseBounds() because it takes node mask as an input. Can you elaborate? Look inside the MinimalShadowMap::ViewData::computeShadowReceiveingCoarseBounds method. C

Re: [osg-users] Shadows and negative renderbin?

Hi Wojtek, I don't think such backporting should be an issue. Practically recent fixes were cosmetics, improved precision in first iteration of shadow camera projection setup and better handling of spot lights. One more thing came to my mind: StandardShadowMap forces RenderBin override on all no

Hi Wojtek, That looks like the problem with boundingBoxVisitor called inside MinimalShadowMap::ViewData::computeShadowReceiveingCoarseBounds() because it takes node mask as an input. Can you elaborate? Btw I started to suspect that there is an error inside above method. Possibly not involved

nodes rendered into shadow map. Maybe this somehow affects your case ? You may comment RenderBin override and see if it changes anything... Wojtek - Original Message - From: "Jean-Sébastien Guay" To: "OpenSceneGraph Users" Sent: Friday, March 05, 2010 6:10 PM Subject: Re

Hi Wojtek, MinimalShadowMap::ViewData::computeShadowReceiveingCoarseBounds() is good place to start looking. Check what are the dimension of returning volume. Good hunting ;-) Thanks for the hint. I'll look there. In the mean time I did more testing and found that even now that I've changed t

Re: [osg-users] Shadows and negative renderbin?

Hi again, I was wondering if someone has had problems with objects which are in negative-numbered renderbins with shadows (in my case, osgShadow::LightSpacePerspectiveShadowMapVB). I should have mentioned that this is using the view dependent shadow classes from OSG 2.8.x backported to OSG 2.

[osg-users] Shadows and negative renderbin?

Hi all, I was wondering if someone has had problems with objects which are in negative-numbered renderbins with shadows (in my case, osgShadow::LightSpacePerspectiveShadowMapVB). I had set up my skydome in renderbin -100 to make really sure it was rendered before other things, and set its no
