Golden Radio. Procedural Animation. Shader Graph.

CREATION #

• Designed and programmed in Unity Engine 2019.4.2 using C# and Shader Graph.

  

• The animation is created by making a graph data structure. The root node branches into 6 smaller subtrees, forming a starfish.

• Each child node is the inverse golden ratio of the parent’s scale.

  • Golden Ratio (φ) #

    \(\varphi = \dfrac{1+\sqrt5}{2}= 1.6180339887…\)

  • Inverse Golden Ratio (1/φ) #

    \(\dfrac{1}{\varphi} = 0.61803398875…\)

• Constant rotation is applied to spin the shape. Rotation speed is a multiple of the golden ratio.

SHADING #

• A fresnel effect is used to create a rim glow effect.

  • See Godot Engine example:
    

    

• Transparency is oscillated by using a sine function.

• Constant rotation is applied to an angled directional light, creating the eclipse effect. Rotation speed is a multiple of the golden ratio.

• Video is captured on a phone to create a retro light-bleeding effect.

MUSIC #

• Song is a lo-fi remix of “In Search of the Man in Black” from Final Fantasy VII:
