BESSEL-1 {
;This formula, and BESSEL-2 to BESSEL-4 are based on
;formulas taken from the article on bessels from the
;Encyclopedia of Science.
c = z = pixel:
z = sin(z) / z * pixel,
|z| <= 100
}
BESSEL-2 {
c = z = pixel:
z = cos(z) / z + pixel,
|z| <= 100
}
BESSEL-3 {
c = z = pixel:
z = -cos(z) / z + sin(z) / (z * z) + pixel,
|z| <= 100
}
BESSEL-4 {
c = z = pixel:
z = -sin(z) / z - cos(z) / (z * z) + pixel,
|z| <= 100
