loadCubeMap
Asynchronously loads six images and creates a cube map. Returns a promise that will resolve to a CubeMap once loaded, or reject if any image fails to load.
Parameters:
| Name | Type | Argument | Default | Description | 
|---|---|---|---|---|
| context | Context | The context to use to create the cube map. | ||
| urls | Object | The source of each image, or a promise for each URL. See the example below. | ||
| allowCrossOrigin | Boolean | <optional> | true | Whether to request the image using Cross-Origin Resource Sharing (CORS). CORS is only actually used if the image URL is actually cross-origin. Data URIs are never requested using CORS. | 
Throws:
- 
DeveloperError : context is required.
- 
DeveloperError : urls is required and must have positiveX, negativeX, positiveY, negativeY, positiveZ, and negativeZ properties.
