Principle

One seed: two circles Then two rules:

• compute tangent circles to current circle pair
• keep only those who do not intersect previous computed circles

Parameters:

• seed circles position and relative radius
• radiuses and side of new tangent circles relative to their parents

Examples

Regular

Seeds equal and tangents Radius Rule: take big circle radius Side rule: both

Conclusion: not very interesting

Near regular

Near regular regular

Seeds equal and tangents Radius Rule: regular range sampling, with range (big * 0.99, big * 0.6) Radius Rule: regular range sampling, with range (big * 0.9, big * 0.6)

Near regular random

Seeds equal and tangents Radius Rule: random range sampling, with range (big * 0.99, big * 0.6)

Others

Seeds equal and tangents Radius Rule: random range sampling, with range (big * 0.6, big * 0.3) Note the convergence at both up and down of the figure.

Random side

Seeds equal and tangents Random side Radius Rule: random range sampling, with range (big * 0.9, big * 0.6), and 3 regular values

Seeds equal and tangents Random side Radius Rule: random range sampling, with range (big * 0.9, big * 0.6), and 10 regular values

Seeds equal and tangents Random side Radius Rule: random range sampling, with range (big * 0.9, big * 0.6), and 4 regular values

Seeds equal and tangents Random side Radius Rule: random range sampling, with range (big * 1.1, big * 0.6), and 4 values
