Constructors

  • Creates a new Tri object.

    Parameters

    • Optionalv0: Vec3 = Vec3.ZERO

      The first 3-dimensional vector.

    • Optionalv1: Vec3 = Vec3.ZERO

      The second 3-dimensional vector.

    • Optionalv2: Vec3 = Vec3.ZERO

      The third 3-dimensional vector.

    Returns Tri

    const v0 = new pc.Vec3(1, 0, 0);
    const v1 = new pc.Vec3(0, 1, 0);
    const v2 = new pc.Vec3(2, 2, 1);
    const t = new pc.Tri(v0, v1, v2);

Properties

v0: Vec3 = ...

The first 3-dimensional vector of the triangle.

v1: Vec3 = ...

The second 3-dimensional vector of the triangle.

v2: Vec3 = ...

The third 3-dimensional vector of the triangle.

Methods

  • Test if a ray intersects with the triangle.

    Parameters

    • ray: Ray

      Ray to test against (direction must be normalized).

    • Optionalpoint: Vec3

      If there is an intersection, the intersection point will be copied into here.

    Returns boolean

    True if there is an intersection.

  • Sets the specified triangle to the supplied 3-dimensional vectors.

    Parameters

    • v0: Vec3

      The value set on the first 3-dimensional vector of the triangle.

    • v1: Vec3

      The value set on the second 3-dimensional vector of the triangle.

    • v2: Vec3

      The value set on the third 3-dimensional vector of the triangle.

    Returns Tri

    Self for chaining

    const t = new pc.Tri(pc.Vec3.UP, pc.Vec3.RIGHT, pc.Vec3.BACK);
    const v0 = new pc.Vec3(1, 0, 0);
    const v1 = new pc.Vec3(0, 1, 0);
    const v2 = new pc.Vec3(2, 2, 1);
    t.set(v0, v1, v2);

    // Outputs [[1, 0, 0], [0, 1, 0], [2, 2, 1]]
    console.log("The result of the triangle set is: " + t.toString());
  • Converts the specified triangle to string form.

    Returns string

    The triangle in string form.

    const t = new pc.Tri(pc.Vec3.UP, pc.Vec3.RIGHT, pc.Vec3.BACK);
    // Outputs [[0, 1, 0], [1, 0, 0], [0, 0, 1]]
    console.log(t.toString());
