(I need to finish an introduction. Read paper in misc.)

from weleber_tobler import kineticfield

kineticfield.compute([(54.7, 1.0), (51, 14.9), ... ])

The result is a dictionary that contains the solid angle and the percent of a sphere it occupies:

{
	'percent_of_sphere': 12.368853569901212,
	'steradians': 1.5543159803411815
}

No idea why the computed steradians are "close enough" but don't match those in the paper for the given input sets (see test_weleber_tobler.py). The equation used seems right:

• Here's a nice introduction to Visual Fields.
• Used Chipmunk Basic for the original code.
• Used this manual as reference for GW-BASIC.

This line means "go to line 400"; it doesn't reassign the array value (d'oh...):

IF RD(I)<90 THEN 400

This means "use double-precision":

RD(I)=90#
