Nice work oscarbarenys1! Porting NBody sample must have taken some time as it has a lot of OSX specific stuff.
Grass-terrain demo is buggy for me, grass changes its position frequently when I press 'forward' key. Also in geometric displacement the ~ key is not working so I am not able to see the better shader!
Ok I remember is a readme.txt or in the doc some file with list current bugs and explain port notes:
Not as much as using Corefoundation libraries from Safari Webkit project!
*Grass terrain is working nice with AMD CPU and Nvidia GPU so seems AMD bug..
*What you mean by forwared key PgFwd.. so it's working?
Also I have changed keyboard shortcuts as I'm spanish and in my keyboard is hard to get some keys..
*better shader is with w or e key I'm in linux now..
