# Star-ScatteringFunctions
-This library defines a set of Bidirectional Reflectance|Transmittance
-Distribution Functions (BRDF & BTDF). It also provides a Bidirectional
-Scattering Distribution Function (BSDF) data structure that is a collection of
-BRDFs and BDTFs that describes the way the light is scattered at a surface.
+This library provides a set of abstractions to describe the way the
+light is scattered at a surface with respect to a geometric optics model. It
+defines interfaces to describe Bidirectional Reflectance|Transmittance
+Distribution Functions (BRDF & BTDF), microfacet distributions and Fresnel
+terms. Several built-in implementation of these interfaces are provided as
+specular, lambertian and microfacet reflections, Beckmann and Blinn microfacet
+distributions, or dielectric/dielectric and dielectric/conductor Fresnel terms.
+
+Finally, complex scattering functions defines as a combination of several BRDFs
+and BTDFs are handled through a Bidirectional Scattering Distribution Function.
## How to build

First ensure that CMake is installed on your system. Then install the RCMake
-package as well as all the aforementioned prerequisites. Then generate the
+package as well as all the aforementioned prerequisites. Finally generate the
project from the `cmake/CMakeLists.txt` file by appending to the
`CMAKE_PREFIX_PATH` variable the install directories of its dependencies.
