I'm sure it can, but effectiveness will depend on what you mean by part. We e.g. use multiple gpu with video streams on multiple monitors. You can also google for equalizer opengl. jp On 18/08/2011 14:37, Miguel Lokida wrote: Hello, I would like to know if OSG can benefit of a PC with

Hi, Did anybody do any further test in using purely native code with OSG? I've just made a simple thing: I've taken the native-activity example from the NDK (r6) and made sure it compiles and run fine. Then, changed a bit the Application/Android mk files to make sure they have the proper paths,

Hi, I had the same problem and ended up overriding the _calculateSize method as you are doing. However, I don't think this is an error of the bounding box. What happens internally is that the text has a width and height according to the first text that we fit in, and it's only updated IF the

Hi Christoph, I think you misunderstood what UnitOut is good for. UnitOut outputs the result to the framebuffer. If you want to combine several osgPPU effects, you would need UnitInOut, since this one does output to a texture, which can be reused. greetings, art meh11 wrote: Hi, I would
