So they are at the brink of bailing out. Parameters Formula: Cubic z = transform(z) z = alpha*z^3 + beta*z^2 + gamma*z + c alpha = 1 + 0i beta = 0 + 0i gamma = -2 + 0i Number of Transforms: 1 Transform 1: top right Complex plane transform: none Initial values of z: c Image centre: 1.331233 + 0.054132i Long side: 0.033919 Rotation about image centre: 0 degrees Bailout condition: norm(z) > 16 Maximum iterations: 1000 Colour selection: outer on bailout otherwise inner Outer: iteration Inner colouring: black Programs: saturn and titan |
