Re: [osg-users] ProgramBinary and shader composition - does it work?

Hi Glenn, The way I'd tackle the issue of compilation of shaders taking a long time is to avoid doing it frame time, doing as much work in scene graph setup/compilation. For you usage case I assume you have a complex shader with many different constant inputs either controlling code paths or valu

Re: [osg-users] ProgramBinary and shader composition - does it work?

Robert, I have an application with several complex shaders. According to the profiler some of them take a while to link (glLinkProgram), long enough to cause a frame drop. This app cannot tolerate any frame drops so I was looking into glProgramBinary as a possible mitigation. I'm open to other ide
