Class: Triangle

SQR.Triangle(v1)

new Triangle(v1)

Represents a triangle composed on 3 vectors. Vectors can be of any size, though some of it methods only work with 2-dimensional vectors.

Parameters:
Name Type Description
v1

Vector SQR.V2 or SQR.V3
Properties:
Name Type Description
centroid SQR.V2

the centroid, undef until calculateCentroid is called.
circumRadius Number

the radius of the circum-circle, undef until calculateCircumCircle is called.
circumCenter SQR.V2

the center of the cirsum-circle, undef until calculateCircumCircle is called.

Methods

calculateCentroid()

Calculates the centroid for this triangle. Only works with 2d coordinates for now. The resulting centroid is stored in the centroid property.

Source:

calculateCircumCircle()

Calculates circumcircle, only works with 2d coordinates.

Based on this and this.

Source:

vertexInCircumcircle(v) → {boolean}

Test whether the point v is inside the triangles circumcircle. If circum-circle was not calculated, calculateCircumCircle will be called first

Parameters:
Name Type Description
v SQR.V2

vertex to be checked
Source:
Returns:

true is vertex is in circumcircle

Type
boolean
