[matlab] Test3Dmodels2 DL : 0: This file contains a set of 3D models with the following characteristics: ■p: nx3 array of 3D points ■t: ntx3 array of triangles id. First points flagged as 1. ■tnorm: ntx3 arrays normals of triangles with outward orientation. You can use this package to test your algorithms. Models can be dowloaded here. All models were created with the new MyRobustCrust. In the new version all triangles have the same orientation, this allows for nice graphics rendering.

[matlab] BallFretting190809 DL : 0: This tool is a simplification of the ballpivoting algorithm. It imagines a bella eating a delaunay traignulation in order to extract a manifold surface. It requires a single parameter: radius of the fretting ball. Ball Fretting Given a uniform sampled filled point cloud returns a tight triangulation. Input: ■tetr: a set of tetraedrons, nx4 array. If the cloud is not tesselated yet you need to call a delaunay triangulator prior calling this function. ■p : nx3 array, 3D set of points. ■r : the only parameter of the algorithm, the radius of the fretting ball Output: ■t : triangles ids, nx3 array ■tnorm: normals of triangles with outwards orientation

[matlab] calcMeshNormals DL : 0: Calculates normals of a mesh. A mesh is without normals if it is constructed using pointCloud2rawMesh.m or is read from a ply or vrml file.

[matlab] pointCloud2rawMesh DL : 0: Same as pointCloud2mesh.m but this one only outputs a mesh. Normals and neighbors of vertices and triangles are NOT calculated to save time. This is sufficient if you want to make a ply or a vrml file of the mesh.

[matlab] shapletsurf DL : 0: Function reconstructs an estimate of a surface from its surface normals by correlating the surface normals with that those of a bank of shapelet basis functions. The correlation results are summed to produce the reconstruction. The sumation of shapelet basis functions results in an implicit integration of the surface while enforcing surface continuity. Note that the reconstruction is only valid up to a scale factor (which can be corrected for). However the reconstruction process is very robust to noise and to missing data values. Reconstructions (up to positive/negative shape ambiguity) are possible where there is an ambiguity of pi in tilt values. Low quality reconstructions are also possible with just slant, or just tilt data alone. However, if you have full gradient information you are better off with the Frankot Chellappa algorithm below.
