RenderScript is 72primarily oriented for use with data-parallel computation, although serial computationally intensive workloads can 73benefit as well. 74 75The RenderScript runtime will parallelize work across all processors available on a device, such as multi-core CPUs, 76GPUs, or DSPs, allowing you to focus on expressing algorithms rather than scheduling work or load balancing. 77RenderScript is especially useful for applications performing image processing, computational photography, or computer 78vision. 79 80This sample demonstrates the fundamentals of writing a RenderScript compute kernel, and using it to perform basic image 81manipulation. In this case, each pixel is transformed based on a liner interpolation between its original 82RGB value and it's luminance (black-and-white) value, weighted based on the user's specified saturation target. 83 84[1]: http://developer.android.com/guide/topics/renderscript/compute.html 85[2]: http://developer.android.com/reference/renderscript/rs__cl_8rsh.html#a254612a612ff7539b01a1478e03d8697 86]]> 87 </intro> 88 </metadata> 89</sample> 90
