The recent introduction of Fortran 90, along with constant increases in the speed of desktop personal computers, makes direct integration an extremely viable means of computing radiation view factors. Using the new intrinsic functions and simplified array operations which are part of the Fortran 90 standard, an algorithm based on discretization of the two surfaces can be implemented in fewer than a hundred lines of code and run in only a few seconds on a typical personal computer. The basics of such an algorithm for arbitrarily oriented flat parallelograms will be reviewed in this brief note.
