Hi there I've been using multisampled floating rt in osg for quite some time, and dont have any problems with them... does your card\drivers support multisampling on float rendertargets? Cheers. 17.08.2012, 14:15, Daniel Schmid daniel.sch...@swiss-simtec.ch: Hi Robert I wonder if this bug

Hi Robert I wonder if this bug has been investigated further or even fixed. Do you have any news concerning this? I face the exact same problem. No AA / multisampling on floating point render targets... Cheers, Daniel -- Read this topic online here:

HI Marco, I have tried combining multi-sampling and float point FBOs so haven't come across this bug before. I do wonder if the _internalFormat itself could be automatically set, or perhaps if it's 0 then RenderStage.cpp code to look for an alternative as a fallback - first it could check for a

Hi Robert, [...], or perhaps if it's 0 then RenderStage.cpp code to look for an alternative as a fallback - first it could check for a texture, then finally drop back to RGBA. Yes, that's basically what my fix does. Send me the changed file and I can pontificate on this. Could you also

[osg-users] cannot get floating-point multisampled FBOs

2008-11-13 Thread Marco Jez
I'm trying to add multisampling capabilities to my floating-point FBOs, but I've found what I think is a bug in osgUtil/RenderStage.cpp. Basically, when I specify a number of samples greater than 0, I actually get a non-floating-point framebuffer. See line 380 in RenderStage.cpp: GLenum
