Karamba.Geometry Namespace

Karamba3D implements its own set of geometric entities so that it can be run independently from RhinoCommon. This makes it e.g. easier to test via unit-tests and allows usage in environments like Dynamo or web-applicaitons. The namespace Karamba.GHopper.Geometry contains extension methods which provide conversion methods from and to RhinoCommon geometry objects via '.convert()'.

Classes

Arc3 Represents a sub-curve of a three-dimensional circle. The arc curve is parametrized by an angle expressed in radians. The parametrization depends on the plane on which the arc/circle is defined. In particular
t => Origin + cos(t)*Radius*XAxis + sin(t)*Radius*YAxis.
AxisAlignedBoundingBox2 an axis-aligned bounding box.
CoordinateSystem3 A class that represent a coordinate system.
Edge3ShellMesh Represents an edge of a ffeb.ShellMesh.
InfiniteLine2 Two-dimensional straight line.
Line2 two-dimensional straight line segment.
Line3Line3Intersection static class for intersecting lines mutually.
Mesh2 a sample implementation of a 2d mesh.
Mesh3 Mesh.
Plane3 3 dimensional plane.
PolyLine3 Polyline.
SimpleLoop2 a sample implementation of a closed polygonal loop.
Vector2 a 2d vector.
Vector3Projector projects vectors on planes, onto vectors or onto themselves. By default it returns the length of the vector.
Vector3ProjectorOnPlane3 return the length of the projection of a vector onto a vector.
Vector3ProjectorOnVector3 return the length of the projection of a vector onto a vector.

Structures

BoundingBox3 3 dimensional bounding box.
ComponentIndex3 Represents an index of an element contained in another object.
DiscontinuityEnhancedPoint1D Coordinate of a 1 dimensional point that is enhanced with an extra info about discontinuity type that takes place.
Edge3 Represents an edge of a Mesh.
Face3 Mesh triangle.
Interval3 Represents an interval in one-dimensional space, that is defined as two extrema or bounds.
Line3 Segment.
Matrix3x2 A structure encapsulating a 3x2 matrix.
Matrix4x4 A structure encapsulating a 4x4 matrix.
Point2 point in UV-space, see https://www.codeproject.com/Tips/862988/Find-the-Intersection-Point-of-Two-Line-Segments.
Point3 3 dimensional point.
Quaternion A structure encapsulating a four-dimensional vector (x,y,z,w), which is used to efficiently rotate an object about the (x,y,z) vector by the angle theta, where w = cos(theta/2).
Segment3 Segment.
Transform3 3-dimensional transformation represented by a 4x4 matrix.
