Point3

class Point3

Point holds three 32-bit floating point coordinates.

Example:

point = skia.Point3(0.0, 0.0, 0.0)
point = skia.Point3((0.0, 0.0, 0.0))  # Convert from tuple
print(point.fX, point.fY, point.fZ)
x, y, z = tuple(point)  # Convert to tuple

Methods

static Point3.CrossProduct(a: skia.Point3, b: skia.Point3) → skia.Point3

Returns the cross product of a and b, treating them as 3D vectors.

static Point3.DotProduct(a: skia.Point3, b: skia.Point3) → float

Returns the dot product of a and b, treating them as 3D vectors.

static Point3.Length(x: float, y: float, z: float) → float

Returns the Euclidian distance from (0,0,0) to (x,y,z)

static Point3.Make(x: float, y: float, z: float) → skia.Point3

Point3.__init__(*args, **kwargs)

Overloaded function.

1. __init__(self: skia.Point3, x: float, y: float, z: float) -> None

2. __init__(self: skia.Point3, t: tuple) -> None

Point3.cross(self: skia.Point3, vec: skia.Point3) → skia.Point3

Point3.dot(self: skia.Point3, vec: skia.Point3) → float

Point3.isFinite(self: skia.Point3) → bool

Returns true if fX, fY, and fZ are measurable values.

Point3.length(self: skia.Point3) → float

Return the Euclidian distance from (0,0,0) to the point.

Point3.makeScale(self: skia.Point3, scale: float) → skia.Point3

Return a new point whose X, Y and Z coordinates are scaled.

Point3.normalize(self: skia.Point3) → bool

Set the point (vector) to be unit-length in the same direction as it already points.

If the point has a degenerate length (i.e., nearly 0) then set it to (0,0,0) and return false; otherwise return true.

Point3.scale(self: skia.Point3, scale: float) → None

Scale the point’s coordinates by scale.

Point3.set(self: skia.Point3, x: float, y: float, z: float) → None

Point3.x(self: skia.Point3) → float

Point3.y(self: skia.Point3) → float

Point3.z(self: skia.Point3) → float

Attributes
