Methods (13)

BarycentricCoordsAt(Point3d point, out double signedHeight)

Gets the projection of a point onto the barycentric coordinates.

ClosestParameterOnBoundary(Point3d point)

Gets the parameter on the triangle boundary closest to a test point.

ClosestPointOnBoundary(Point3d point)

Gets the point on the triangle boundary closest to a test point.

PointAlongBoundary(double t)

Gets the point along the boundary of the triangle. The triangle boundary has a domain [0, 3] where each subsequent unit domain maps to a different edge.

PointAtBarycentricCoords(Point2d coords)

Gets a point within this triangle using barycentric coordinates.

PointOnInterior(double u, double v)

Gets the point on the triangle using the AB and AC primary axes.

ToMesh()

Create a mesh from this triangle.

ToPolyline()

Create a polyline from this triangle.

Transform(Transform transform)

Transform this triangle.

TrySmallestEnclosingTriangle(IEnumerable<Point2d> points, double tolerance, out Triangle3d triangle)

Attempt to create the smallest triangle containing a set of planar points.

WithA(Point3d a)

Replace the A corner.

WithB(Point3d b)

Replace the B corner.

WithC(Point3d c)

Replace the C corner.
