Shadow Mapping in OF

Greetings, Does anyone know of a decent shadow mapping implementation implemented in OF ?

Thank You arturo. I tried to build a project to compile the example, but there is a compilation issue (VS on Windows) with version 10.1 I have not had a chance to look into it yet:

‘ofParameterglm::quat::Value::value’ uses undefined struct ‘glm::tquat<float,0>’ (compiling source file …\addons\ofxShadowMap\src\ofxShadowMap.cpp)
