raygeo.geo.shape.circle

Circle geometry queries.

Provides circle-circle and circle-rectangle intersection detection, circle-rectangle full-containment checks, line-segment-vs-circle intersection, and point projection onto a circle's circumference.

Functions

does_circle_intersect_rect()

does_circle_intersect_rect(center: Point, radius: float, rect: Rect) -> bool

Check if a circle intersects a rectangle.

Returns: True if the circle intersects the rectangle.

Parameter	Type	Description
center	Point	Circle center (x, y).
radius	float	Circle radius.
rect	Rect	Rectangle (x_min, y_min, x_max, y_max).
Returns	bool

get_circle_circle_intersections()

get_circle_circle_intersections(c1: Point, r1: float, c2: Point, r2: float) -> Polygon

Get intersection points of two circles.

Returns: List of intersection points (x, y).

Parameter	Type	Description
c1	Point	Center of first circle (x, y).
r1	float	Radius of first circle.
c2	Point	Center of second circle (x, y).
r2	float	Radius of second circle.
Returns	Polygon

is_circle_inside_rect()

is_circle_inside_rect(center: Point, radius: float, rect: Rect) -> bool

Check if a circle is inside a rectangle.

Returns: True if the circle is fully inside the rectangle.

Parameter	Type	Description
center	Point	Circle center (x, y).
radius	float	Circle radius.
rect	Rect	Rectangle (x_min, y_min, x_max, y_max).
Returns	bool

line_segment_intersects_circle()

line_segment_intersects_circle(p1: Point, p2: Point, circle_center: Point, circle_radius: float) -> bool

Check if a line segment intersects a circle.

Returns: True if the line segment intersects the circle.

Parameter	Type	Description
p1	Point	Start point of the line segment (x, y).
p2	Point	End point of the line segment (x, y).
circle_center	Point	Circle center (x, y).
circle_radius	float	Circle radius.
Returns	bool

project_point_onto_circle()

project_point_onto_circle(point: Point, center: Point, radius: float) -> Optional[Point]

Project a point onto a circle.

Returns: Projected point on the circle (x, y).

Parameter	Type	Description
point	Point	Point to project (x, y).
center	Point	Circle center (x, y).
radius	float	Circle radius.
Returns	Optional[Point]
