h1. The YoGA simulation tool 

 
 YoGA is a plugin for "Yorick":http://dhmunro.github.com/yorick-doc/ built on top of "NVIDIA's CUDA toolkit":http://developer.nvidia.com/category/zone/cuda-zone. It provides GPU acceleration from within the Yorick environment for a number of applications (Fourier transform, matrix operations, random number generation, etc ..).  

 YoGA_AO is an extension to the YoGA plugin for Yorick, providing efficient tools to simulate a wide range of adaptive optics systems at various scales. General software design has been inspired by "YAO":http://frigaut.github.com/yao/index.html, a simulation tool developed by François Rigaut. Main features include : 
 * on-line multiple layers Kolmogorov turbulence generation at various altitudes 
 * multi-directional raytracing through turbulence 
 * multi-directional Shack-Hartmann (SH) spots computation using either natural or laser guide stars 
 * centroiding on SH spots using various algorithm : center of gravity (COG) , weighted COG, thresholded COG, brightest pixels COG 
 * Least square command strategy 
 * Realistic piezostack deformable mirror model 

 The following wiki pages will guide you through the installation and use of the simulation tool.
