View3D: calculation of radiation view factors in 2D and 3D

View3D is a command-line tool for evaluating radiation view factors for scenes with complex 2D and 3D geometry. It uses an adaptive integration method to calculate the view factors between faces where there is partial obstruction from inbetween faces.

This program can be used to calculate the view factors (aka shape factors/configuration factors/form factors) for radiant heat transfer in diffuse grey enclosures.
