View source for Render To Texture

Render To Texture (RTT) is a method to capture a view of the game and turn it into an image. This image can be stored in a framebuffer and updated frequently.

RTT is commonly used for reflective water in a game. A camera is placed below the water surface, looking up. The image it captures is then textured onto the water surface, looking like a live reflection.
