Dynamic Cubemapping using MOGRE

This video shows a refractive object getting its cubemap dynamically created during runtime. The demo can be downloaded here: http://l4nm4n.users.sourceforge.net/skyblue/data/uploads/mogre_dynamiccubemap... . The wiki page explaining this process in detail can be found here: http://www.ogre3d.org/wiki/index.php/Dynamic_Cubemapping_using_MOGRE .

This is what Half-Life 2: Episode Three needs

@ErrorSuper Absolutely. I think the guys at Valve already use cubemapping but precomputed at map compile time (you set up env_cubemap entities). This is not as flexible as doing cubemapping in real-time. Probably they do this for performance reasons, since this technique takes a lot of processing power.

Way better for performance, since it's using six textures per cubemap rather than something like six RT cameras.
