MatGeom release v1.2.2
MatGeom is a library for geometric computing with Matlab. It is organized is several modules for 2D geometry, 3D geometry, polygon processing, or mesh processing.
Installation
The "matGeom-X.Y.Z.zip" file contains the functions of the library. The "matGeom-X.Y.Z-full.zip" additionnally contains demonstration files and unit test framework.
After decompressing, the script "setupMatGeom" should properly install the whole library.
Main changes are improvements in drawing functions, and in the management of Euler angles.
Added
- (geom2d) added function principalAxesTransform
- (polygons2d) added polygnSkeleton function
- (polygons2d) added clipPolyline function
- (graphs2d) added adjacencyListToEdges function
- (geom3d) added function normalizeLine3d
- (geom3d) added function fitSphere
- (geom3d) added functions drawDome and drawCapsule
- (geom3d) added function drawAngleBetweenVectors3d
- (geom3d) added drawRay3d and clipRay3d
- (meshes3d) added averageMesh function, to compute an average mesh from several mesh instances
- (meshes3d) added meshComplement
- (meshes3d) added function fillMeshFaces
Changed
- (geom2d) fitAffineTransform2d: changed convention for source and target point sets
- (polygons2d) polygonSubcurve and polylineSubcurve now also return indices of selected vertices
- (geom3d) improvements in management of Euler Angles in rotation3dToEulerAngles and eulerAnglesToRotation3d
- (geom3d) drawCylinder can now handle multiple cylinders as numeric arrays
- (geom3d) several updates to drawing functions
- (geom3d) make some vector operations more generic about dimension
- (geom3d) fitAffineTransform3d: changed convention for source and target point sets
- (meshes3d) reading of OFF files is now faster when faces have homogeneous number of vertices
- (meshes3d) readMesh_ply.m: replaces error by warning
Regression
- (geom2d) removed functions rad2deg and deg2rad, as they can be replced by Matlab native functions
