Define the camera used to render the texture.
Define the list of animation attached to the texture.
With compliant hardware and browser (supporting anisotropic filtering) this defines the level of anisotropic filtering in the texture. The higher the better but the slower. This defaults to 4 as it seems to be the best tradeoff.
Gets or sets the center of the bounding box associated with the texture (when in cube mode) It must define where the camera used to render the texture is set

In case the RTT has been created with a depth texture, get the associated depth texture. Otherwise, return null.
Define if the texture contains data in gamma space (most of the png/jpg aside bump). HDR texture are usually stored in linear space. This only impacts the PBR and Background materials

This Helps creating a texture that will be created from a camera in your scene. It is basically a dynamic texture that could be used to create special effects for instance. Actually, It is the base of lot of effects in the framework like post process, shadows, effect layers and rendering pipelines...
