Detailed Description

The ScalarVolume node defines an scalar field by specifying an image file and loaders to read this file.

The data is read from the URL specified by the url field using the H3DImageLoaderNode nodes from the imageLoader field. The data used will be the first texture that is successfully loaded. Each file in the url field be tried with the first H3DImageLoaderNode, if none of those succeed the next H3DImageLoaderNode will be tried on all the urls and so on.
