geom-sweep

Extrudes a shape along a path.

Usage

var sweep = require('geom-sweep')
var g = sweep(path, shape, opts)

API

sweep(path, shape, opts)

• path - array of [x, y, z] positions defining the path to extrude along
• shape - array of [x, y, z] positions defining the swept shape
• opts - options
• opts.radius - extruded geometry radius (default 1)
• opts.initialNormal - provide a starting normal for the frames. Default to the direction of the minimum tangent component (default undefined)
• opts.closed - is the path closed? (default false)
• opts.caps - add caps at the end? (default false)
• opts.closedShape - is the shape path closed? (default true)
• opts.debug - add debugLines: [] with the frames vectors concatenated in the form [point, tangent, point, normal, point, binormal] (default false)

Returns new geometry: { positions: [], normals: [], tangents: [], uvs: [], cells: [] }
