Graphics.Rendering.Handa.Face

Functions and types for managing objects represented as collections of faces.

Types

type Face a = [(a, a, a)]

A face is a collections of the vertices on its boundary.

type Edges a = [(a, a, a)]

Edges are paired series of triple of vertex components.

faceToEdges :: Face a -> Edges a

Convert a face to a

Rendering
