Used by the CubeCamera as its WebGLRenderTarget.
See CubeCamera for examples.
width - The width of the renderTarget.
height - The height of the renderTarget.
options - (optional) object that holds texture parameters for an auto-generated target texture and depthBuffer/stencilBuffer booleans. For an explanation of the texture parameters see Texture. The following are valid options:
wrapS - default is ClampToEdgeWrapping.
wrapT - default is ClampToEdgeWrapping.
magFilter - default is .LinearFilter.
minFilter - default is LinearFilter.
format - default is RGBAFormat.
type - default is UnsignedByteType.
anisotropy - default is 1. See Texture.anistropy
encoding - default is LinearEncoding.
depthBuffer - default is true. Set this to false if you don't need it.
stencilBuffer - default is true. Set this to false if you don't need it.
Creates a new WebGLRenderTargetCube
The activeCubeFace property corresponds to a cube side (PX 0, NX 1, PY 2, NY 3, PZ 4, NZ 5) and is used and set internally by the CubeCamera.
