What Does BSDF Stand For?

BSDF stands for Bidirectional Scatter Distribution Function

The Bidirectional Scatter Distribution Function (BSDF) is a mathematical representation that characterizes the scattering properties of materials. It defines how incident light is distributed in various directions after interacting with a surface, capturing both reflection and transmission effects. BSDF is crucial in fields such as optics, rendering, and architectural design, as it enables accurate simulations of light behavior in both natural and artificial environments. By providing a comprehensive understanding of light-material interactions, BSDF facilitates improved visual realism and energy performance in applications ranging from computer graphics to daylighting analysis.
