3D in Flash
From CasparCG Wiki
Using Adobe Flash Player 10 and later, you can use Flash's built-in cameras and 2.5D abilities in your Category:Flash Templates.
There are also 3rd party Flash 3D engines such as Papervision3D that can be used.
Although the current version of CasparCG Server doesn't have any interfaces to real-time 3D camera tracking systems, such an interface could be developed to allow virtual 3D sets.
