Types

type Line

type Line struct {
	End [2]Point
}

A Line is a line segment in 3D space, denoted by two Points

type Point

type Point struct {
	X, Y, Z float32
}

A Point is a point in 3D space.

func (Point) Equals

func (p1 Point) Equals(p2 Point) bool

type Scene

type Scene struct {
	Header    [80]byte
	Triangles []Triangle
	Bounds    Subspace
}

A Scene holds all of the contents of an STL file, as well as derived values.

func Decode

func Decode(r io.Reader) (s Scene, err error)

Decode reads an entire STL file from a Reader, returning a Scene.

type Subspace

type Subspace struct {
	Min Point
	Max Point
}

A Region is a region of the coordinate space from Min to Max

type Triangle

type Triangle struct {
	Normal Vector
	Vertex [3]Point
	Attr   uint16
}

A Triangle is a triangle in 3D space, denoted by three Points. The "outside" of the triangle is denoted by its normal vector.

type Vector

type Vector struct {
	X, Y, Z float32
}

func (Vector) Abs

func (v Vector) Abs() float32

func (Vector) IsNormal

func (v Vector) IsNormal() bool
