An Informal Preliminary Collection of Radiance Materials Definitions

As Giulio's says: "An experimental repository for daily Radiance brain teaser... in the hope to be able to share something."

Official Radiance Server

In a full lighting simulation such as provided by Radiance, the visual properties of an object start with color, but include a full set of optical charateristics, based on a material type and modifiers such as pattern and texture ...

As said by Carsten Bauer, the Radzilla author:
"RADZILLA is a port of the well known physically based ray tracer RADIANCE to the C++ programming language. The project is both aimed at gaining experience in C++ programming and software developoing in general as well as at the modification and optimization of RADIANCE for complex visualization applications (architecture/art/design etc).

HDRShop can make HDR images from LDR photographs, taken with different exposures. Some image processing operations are included as well.

An exhaustive article about High Dynamic Range Image Encodings, by Greg Ward

Qtpfsgui is a graphical user interface that enables users to work on hdr images. Supported operations include: * creations of a HDR file from a set of images of a scene taken at different exposure settings * tonemapping an HDR image into a common LDR image format (e.g jpeg or png) * loading, saving and rotating existing HDR images Qtpfsgui is available both for linux and windows.

An opensource library and a set of commandline tools for reading, writing, manipulating and viewing high-dynamic range (HDR) images and video frames. All programs in the package exchange data using a simple generic file format (pfs) for HDR data. The concept of the pfstools is similar to netpbm package for low-dynamic range images.
