[osg-users] osg::Texture2DMultisample

Hi, maybe this seems like s stupid question but why does osg::Texture2DMultisample does not have a getNumSamples() function? This might come in handy if, like in my case, a texture is passed around for MRT binding (camera-attach), to determine the number of samples for the attach function.

Re: [osg-users] [osgPlugins] OSG 3.2.x slower than OSG 3.0.1??

Hi Tim, I'm doing the same thing right now. I also experienced some performance problems with trunk vs. 3.1.8 on Visual Studio 2010 x64. Currently I'm rebuilding from scratch, so if there are any news I'll let you know. The major change in the core is related to geometry. But as far as I can

Re: [osg-users] blending on multiple targets

Hi Bram, Hi, thanks for the reply! I get the undefined part, that makes sense, but what I still don't understand though: I just specify blending (GL_BLEND on) is on in the nodes. But then if I do gl_FragData[0] = vec4(0,0,0,0); then it doesn't seem to matter anymore what I write to

Re: [osg-users] Is it possible to use EffectCompositor to describe effects per object?

Hi Michael, I solved a similar problem by overriding osg::Program which composes a shader from an Ubershader. This is not done via uniforms but defines. It seems to work somehow and improved the performance over branching based on uniforms. Hi. I decided to go with single pipeline that

Re: [osg-users] Is it possible to use EffectCompositor to describe effects per object?

please provide an example of how an object manages its define-set? In my case, I simply get the object's StateSet and setup uniforms. But I don't get how to setup defines. Thanks. 2013/11/7 Sebastian Messerschmidt sebastian.messerschm...@gmx.de mailto:sebastian.messerschm...@gmx.de Am
