In cxhull: Convex Hull

cxhull 0.7.4

• The faces of the mesh returned by the hullMesh function are now given by the vertex indices of this mesh, while in the previous versions they were given by the vertex indices of the original vertices (those for which the convex hull is computed).

• The hullMesh function can now return a 'rgl' mesh.

• The package does no longer depend on the 'Morpho' package.

cxhull 0.7.3

New argument alpha in the plotConvexHull3d function, to control the transparency of the faces.

cxhull 0.7.2

Fixed a small mistake in the C code.

cxhull 0.7.1

Replaced sprintf with snprintf in the C code.

cxhull 0.7.0

• New function hullMesh to extract the vertices and the faces of a 3d convex hull.

• Updated the vertices of Leonardo da Vinci's 72-sided sphere; the new ones are more accurate.

cxhull 0.6.0

• New function dihedralAngles which computes the dihedral angles of a 3d convex hull.

• New argument angleThreshold in the plotConvexHull3d function. Edges whose corresponding dihedral angle is greater than angleThreshold are removed from the plot.

cxhull 0.5.0

• New function cxhullEdges, which computes only the vertices and the edges of a convex hull (for speed gain and less memory consumption).

cxhull 0.4.0

• New function hullSummary, which returns a summary of a 3D triangulated convex hull.

• Now, the facesColor argument of plotConvexHull3d can be a vector, allowing to assign different colors to the faces. See the README file for examples.

• The plotConvexHull3d function has a new argument palette; it allows to decorate the faces with a color gradient.

• Updated the README file.

cxhull 0.3.0

• New function plotConvexHull3d, to easily plot a 3D convex hull, with a correct orientation of the facets.

• A couple of other new functions, e.g. EdgesAB, which returns a matrix representing the edges and indicating which edges are on the border of the convex hull. These functions are used by plotConvexHull3d, they are not of great interest otherwise.

cxhull 0.2.0

• New component of facets: orientation, indicating the facet orientation.

cxhull 0.1.1

• Maintenance release.

cxhull 0.1.0

• First release.
