General geometry functions.
- pylinkage.geometry.bounding_box(locus)¶
Compute the bounding box of a locus.
- locuslist[tuple[float]]
A list of point or any iterable with the same structure.
- tuple[float]
Bounding box as (y_min, x_max, y_max, x_min).
- pylinkage.geometry.circle_intersect(circle1, circle2, tol=0.0)¶
Return the intersections between two circles.
Transcription of a Matt Woodhead program, method provided by Paul Bourke, 1997. http://paulbourke.net/geometry/circlesphere/.
circle1: first circle, sequence of (abscisse, ordinate, radius) circle2: second circle, sequence of (abscisse, ordinate, radius) tol: distance under which two points are considered equal.
- pylinkage.geometry.cyl_to_cart(radius, theta, ori=(0, 0))¶
Convert polar coordinates into cartesian.
radius: distance from ori theta: angle is the angle starting from abscisses axis ori: origin point.
- pylinkage.geometry.dist_builtin(point1, point2)¶
Euclidian distance between two 2D points.
Legacy built-in unoptimized equivalent of math.dist in Python 3.8.
- pylinkage.geometry.intersection(obj_1, obj_2, tol=0.0)¶
Return intersection between two objects (points or circles).
Return nothing of no intersection. tol: absolute tolerance to use if provided.
- pylinkage.geometry.norm(vec)¶
Return the norm of a 2-dimensional vector.
- pylinkage.geometry.sqr_dist(point1, point2)¶
Square of the distance between two points.
Faster than dist.
