Detailed Description

Abstract interface for isotropic BSDF data.

The isotropic BSDF data is modeled as a three-dimensional grid of values. The three dimensions of the grid are called theta_in, theta_out, and phi_in. The values can be of two types: scalars or RGB values (see Bsdf_type). The grid values are uniformly distributed in the range [0,pi/2) for theta_in and theta_out and in the range [0,pi] for phi_in. The resolution, i.e., the number of values, of each dimension is arbitrary with the limitation that the resolution for theta_in and theta_out has to be identical.
