I recently found out that though Animations do a great job super-cool stuffs in QML are done using shaders. Now I know nothing about this. One eg I found out is here:

I would certainly like to add such effects to my project but I know nothing about shaders. However I've programmed in WPF3D - C# in the past on 3D modelling of real-world surfaces so I have some knowledge of mesh, geometry, texture etc. I want some advice on how do I start learning the usage of Shaders in QML. Do i need to study OpenGL 1st or some specific offerings of OpenGL or something called GLSL? Is there any other way i can have those effects (for eg the one in the link i posted)?
