Re: [osg-users] Non-Inlined Shaders in OSG files

Hi Kim, a while ago (maybe one year ago), I've submitted a patch to do so. There exists now an osg plugin for .glsl files, which can load the shaders, hence non-inlined support is possible. Evenmore, there is a possibility to enable non-inlined shader support when writing .osg files. Take a

Hi Jason, take a look into osgPPU's CMake files. There I use the output of osgversion to find out the version number of the current osg. In this way you could determine the version and install the plugin where you need them. Best regards, art -- Read this topic online here:

Hi Jason, sorry, so that you don't search long time before find the correct thing, just take a look into OsgPPUMacroUtils.cmake in CMakeModules directory. The very first macro is what you are looking for. Then jus call this macro somehwerte from your main cmake file and evrything will be fine

Hi Robert, Ok, I understand what you means. However I do not understand what you means with high level encapsulation of camera class. There exists an additional shader class derived from osg::Program, which offers more functionality than a usual osg::Program. Current osgPPU doesn't force you

Hi folks, The community becames bigger and bigger and there are more and more projects/nodekits which offers additional features to osg. And therefor I think OSG 3.0 is the best time to refactor the whole nodekit maintaining structure. Hence here are couple of ideas, how to do so. In my

Hi Roland, yes the mail wasn't answered, hence I didn't make any pressure on that. My current release strategy is to release one osgPPU version for each osg stable version. Hence as soon as 2.8 comes out, I will release osgPPU v0.4, which will only be compatible with osg 2.8 However, of

Hi Markus, yeah, there is indeed some special option to set when build Cuda. You have to setup CUDA_BUILD_TYPE to Device instead of Emulation. Type in your build directory ccmake and resetup the value. Or just call cmake -DCUDA_BUILD_TYPE=Device. The problem is in the cuda compiler, as far as
