 !{width:20%}https://projets-lesia.obspm.fr/attachments/download/691/yoga_carre_NB.png! 

 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 ..).

 h1. *YoGA_AO* 

 YoGA_AO is an extension to YoGA 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 
 * more to come ...
