- Abstract
- This report describes the use of adaptive integration for the calculation of view factors between simple convex polygons with obstructions. The accuracy of the view factor calculation is controlled by a convergence factor. The adaptive integration method is compared with two other common methods implemented in a modern computer program and found to have significant advantages in accuracy and even advantages in computational speed in some cases.
