cubeMap(withContentsOfFile:options:)
Loads a cube map texture image from a single file and creates a new texture from the data.
Declaration
class func cubeMap(withContentsOfFile path: String, options: [String : NSNumber]? = nil) throws -> GLKTextureInfoParameters
- path:
A path to the file to load.

A dictionary that describes any additional steps you want the texture loader to take when loading the texture. See Texture Loading Options.
Return Value

Discussion
The file is assumed to be a single image that includes the six faces of the cube map. The image’s height must be six times the width, and the images should be arranged in the following order from top to bottom: north, south, east, west, top, bottom. Alternatively, the image can have a width that is six times the height, and arranged from left to right, but this takes additional processing to load.
This class method loads the texture into the sharegroup attached to the current context for the thread this method is called on.
