Detailed Description

To load the IES file image format. IES files exist for many real world lights. The file stores how much light is emitted in a specific direction. The data is usually measured but tools to paint IES files exist.

Constructor & Destructor Documentation

FIESConverter()

FIESConverter::FIESConverter	(	const uint8 *	Buffer,
		uint32	BufferLength
	)

is loading the file, can take some time, success can be checked with IsValid()
