Return shape points of two splitting liquid shapes, kind of how cells divide. Shape_liquid_splitting(radius, centre_dist) Return points on the path of a regular cyclic polygon. Shape_cyclicpolygon(sides, circle_r, corner_r) Return points on the path of an arc shape. Take a 2D polygon as input and extend it onto a sphere. Rounded_extrude(size, round_r)Įxtrude a 2D object roundly from 0 to 180 degrees. It returns a vector of, ].īend_extrude(size, thickness, angle)īox_extrude(height, shell_thickness, bottom_thickness)Ĭreate a box (container) from a 2D object.Įllipse_extrude(semi_minor_axis, height)Įxtrude a 2D object along the path of an ellipse from 0 to 180 degrees. Sphere_spiral(radius, za_step)Ĭreate all points and angles on the path of a spiral around a sphere. Get all points on the path of a spiral around a cylinder. The distance between two points is almost constant. Get all points and angles on the path of a golden spiral based on Fibonacci numbers. Nearest-neighbor points will all be approximately the same distance apart. An implementation of Centripetal Catmull-Rom spline.Ĭreate visually even spacing of n points on the surface of the sphere. Given a set of control points, this function returns points of the Bézier path.īspline_curve(t_step, degree, points, knots, weights)ī-spline interpolation using de Boor's algorithm.Ĭreate a curved path. Successive points will all be approximately the same distance apart. Get all points and angles on the path of an archimedean spiral.Ĭreate visually even spacing of n points on the surface of the sphere. Given a 2D path, this function constructs a mid-point smoothed version by joining the mid-points of the lines of the path.Īrchimedean_spiral(arm_distance, init_angle, point_distance, num_of_points) Given an edge path with the first point at the outline of a shape, this function uses the path to calculate scaling factors and returns all scaled sections in the reversed order of the edge path. Path_scaling_sections(shape_pts, edge_path) Lines_intersection(line1, line2)įind the intersection of two line segments. Given a 2D shape, points and angles along the path, this function returns all cross-sections. Trim a tangled-edge shape to a non-tangled shape.īezier_smooth(path_pts, round_d)Ĭross_sections(shape_pts, path_pts, angles) Each point of the offsetted shape is paired with exactly one point of the original shape.Ĭompute contour polygons by applying marching squares to a rectangular list of numeric values. Move 2D outlines outward or inward by a given amount. Hull each pair of joins and union all convex hulls. Shear all child elements along the X-axis, Y-axis, or Z-axis. If there's only one child, put the child for each point. Rounded_cylinder(radius, h, round_r)ĭevelop a smooth skin from crosssections with the same number of sides.Īlong_with(points, angles) Polyline3d(points, diameter)Ĭreate a polyline from a list of.
