All underlying openCL objects are accessible to allow advanced features too if need be.\nDemo (1M particles @ 100-200 fps) at [vimeo.com/7332496](http://vimeo.com/7332496)\n\nLicence\n-------\nThe code in this repository is available under the [MIT License](https://secure.wikimedia.org/wikipedia/en/wiki/Mit_license).  \nCopyright (c) 2008-2012 Memo Akten, [www.memo.tv](http://www.memo.tv)  \nThe Mega Super Awesome Visuals Company\n\nSome Windows \u0026 OpenGL / interop specific additions (c) [tgfrerer](http://poniesandlight.co.uk), placed under MIT license. \n\n\nInstallation\n------------\nCopy to your openFrameworks/addons folder.\n\nI've had some problems on 10.8 with OpenCL. I've had to install these drivers [www.nvidia.com/object/cuda-mac-driver.html](http://www.nvidia.com/object/cuda-mac-driver.html) for my graphics card to work.\n\n## Windows / VS 2012 \n\nOn Windows using Visual Studio, make sure to point your compiler to the right location of the OpenCL headers. You'll find an example ```.props``` property file in ```libs/OpenCL/lib/vs/``` - this file should work for the latest Windows CUDA/OpenCL Nvidia SDK. You can add it to your project by clicking \"Add Existing Property Sheet\" in the vs2012 Property Manager window. If it doesn't work, inspect it using a text editor and make sure the path to the OpenCL headers is correct for your development system.\n\nDependencies\n------------\n\n### Windows / NVidia\n\n* CUDA SDK [https://developer.nvidia.com/cuda-downloads]\n\n### Examples\n\nSome examples also require [ofxMSATimer]{https://github.com/memo/ofxMSATimer}\n\nCompatibility\n------------\nopenFrameworks 0.8+  \nI am generally testing only with [openFrameworks](www.openframeworks.cc), however it should work with [Cinder](www.libcinder.org) too. If it doesn't, please file an issue.\n\n\nKnown issues\n------------\nnone\n\nVersion history\n------------\n### v2.3\n- additions for safe OpenGL/OpenCL interop on windows and OS X\n- reliable detection of platforms and devices on windows, OS X\n- MSAOpenCLBufferManagedT to be compatible with GL interop elements (see particle example) \n### v2.2\n- MSAOpenCLBufferManagedT: Memory Object High level wrapper, allocates and manages host and client memory objects\n### v2.1    23/09/2012\n- compatible with OF0072\n- renamed (uppercase) MSA namespace to (lowercase) msa. (kept MSA as an alias for backwards compatibility)\n- no longer requires MSACore\n\n### v2.0\n- move to centralized MSALibs (requires MSACore)\n- everything is MSA:: namespace\n\n### v0.3\n- added image support\n- restructured buffer/memory management\n- minor break in backwards compatability: createBuffer returns ofxOpenCLBuffer instead of cl_mem. so\n   - writeBuffer and readBuffer are methods of ofxOpenCLBuffer, not ofxOpenCL\n   - when passing buffer (or image) as parameter to ofxOpenCLKernel::setArg, use ofxOpenCLBuffer::getMemoryObject() (which returns the cl_mem)\n\n### v0.2\n- added support for multiple devices\n- sharing context with opengl (only on mac osx at the moment)\n- better handling of multi-dimensional data (minor backwards compatability break with kernel::run)\n- support for opengl/opencl buffer+texture sharing \n- can load programs from binary (support for creating binary coming soon)\n\n\n### v0.1\n- initial version\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmemo%2Fofxmsaopencl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmemo%2Fofxmsaopencl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmemo%2Fofxmsaopencl/lists"}
