fv is an HDRI viewer that uses the OpenGL API and GLUT so that it is highly portable. It currently supports the HDR Radiance/PIC/RGBE and Portable Float Map formats. High Dynamic Range images have a much greater amount of illumination information than can be reproduced with a standard display device or captured using a conventional camera with a single exposure. They are made by combining multiple normal images of the same scene taken with different intensity levels, or are the result of creating a global illumination rendering. The environment provides not just reflections but the full intensity of any natural or artificial light source present.
