A Biologically-Parameterized Feather Model

How to read this

Category

Method: a procedural model of an individual feather

Contributions

• A feather parameterization derived from the biological structure and substructures of real feathers
• Bezier-curve based descriptions of the rachis and barbs that generate varied feather types at multiple levels of detail
• A first step toward semi-automatically generating full feather coats for CG characters

Context

Relates to procedural and biologically inspired modeling of natural structures, grounding feather geometry in real feather anatomy rather than ad hoc geometry.

Correctness

Presented as a single-feather modeling approach validated by the variety of feathers it can generate; reader caveat is that it is an early step toward full coats, so coverage, layout, and rendering of complete plumage are largely out of scope here.

Clarity

Accessible; a single first pass likely conveys the parameterization, with a second pass only if you need the curve construction details.

How to read it

Focus on the biological-to-Bezier mapping (rachis and barbs) and the level-of-detail control; one pass is enough unless you are implementing the geometry.
