raygeo.geo.types

Type aliases used throughout the raygeo API.

Point — a 2D coordinate as (x, y). Point3D — a 3D coordinate as (x, y, z). Point2DOr3D — union of Point and Point3D for functions that accept both. Polygon — a list of points forming a closed shape. Rect — a bounding rectangle as (x_min, y_min, x_max, y_max). TransformMatrix — a 4x4 affine transformation matrix for 2D/3D transforms. Edge — a pair of points ((x1, y1), (x2, y2)). CubicBezier — four control points (p0, p1, p2, p3). IntPoint / IntPolygon — integer-coordinate variants for Clipper.

Type Aliases

Point

Type: tuple[float, float]

Type: Point | Point3D

Point3D

Type: tuple[float, float, float]

Polygon

Type: list[Point]

Rect

4x4 affine transformation matrix for 2D/3D coordinate transforms.

Layout (row-major):

[ Rxx  Rxy  Rxz  Tx ]   row 0: X basis vector + X translation
[ Ryx  Ryy  Ryz  Ty ]   row 1: Y basis vector + Y translation
[ Rzx  Rzy  Rzz  Tz ]   row 2: Z basis vector + Z translation
[  0    0    0   1  ]   row 3: homogeneous row (identity)

For 2D transforms, set the Z components to identity: Rzx = Rzy = 0.0, Rzz = 1.0, Tz = 0.0
