Shape Grammars of Ice-ray Chinese Lattice Designs : haldane liew


Shape Grammars of Ice-ray Chinese Lattice Designs : haldane liew: "Type II designs approach the generation of the ice-rays in a dynamic manner. The rules essentially bisects any existing polygonal shape into two polygonal shapes. Variations for this grammar typically consist of changing the resultant shape from two shapes to many shapes that create a triangular or rectangular shape towards the center."

Type II : parametric shape grammar rules
Rules and Implementation

Rules:





rule 1 : 3 sided polygon -> 3 sided + 4 sided polygon

rule 2 : 4 sided polygon -> 4 sided + 4 sided polygon

rule 3 : 4 sided polygon -> 3 sided + 5 sided polygon

rule 4 : 5 sided polygon -> 4 sided + 5 sided polygon

variation of rule 2 & 3

4 sided polygon -> 3 sided + 4 sided(2) + 5 sided polygon
