Builds a Plane3 from four coefficients a, b, c, d, a Vector4, a normal and a d, or a normal and a point on the plane (then d = -dot(normal, point)). The normal is stored as given; it is not normalized.
p := make_plane(xyz(0, 0, 1), xyz(0, 0, 3)); // the plane z = 3
assert(p.d == -3);
assert(make_plane(1, 2, 3, 4).d == 4 && make_plane(xyz(1, 2, 3), 4).normal == xyz(1, 2, 3));make_plane :: (a: float, b: float, c: float, d: float) -> Plane3A plane from its coefficients, for the plane a*x + b*y + c*z + d = 0.
Parameters
- a: float
- the normal's x.
- b: float
- the normal's y.
- c: float
- the normal's z.
- d: float
- the offset.
Returns
make_plane :: (v: Vector3, d: float) -> Plane3A plane from a normal and an offset.
Parameters
- v: Vector3
- the normal.
- d: float
- the offset, added after the dot product with the normal.
Returns
make_plane :: (v: Vector3, x: Vector3) -> Plane3A plane with the given normal that passes through a point.
Parameters
Returns
make_plane :: (v: Vector4) -> Plane3A plane from a vector holding the normal in x, y, z and the offset in w.
Parameters
- v: Vector4
- the normal in x, y, z and the offset in w.
