# == # List of functions == === metchgui.m === ` alldata = metchgui(node,elem,points) or metchgui(volume,points)` A GUI to register a point cloud to a mesh or volumetric image parameters: node: node coordinate of the surface mesh (nn x 3) elem: element list of the surface mesh (3 columns for triangular mesh, 4 columns for cubic surface mesh) the input can also be two parameters in form of metchgui(volume,points), where volume is a 3D image (array).

The toolbox also provides point cloud registration, geometrical shape fitting to 3-D point clouds, and the ability to read, write, store, display, and compare point clouds. You can also combine multiple point clouds to reconstruct a 3-D scene.

Based on these curvature information I would select the points, that may belong to some geometric shape in the point cloud (e. g. to some planes, spheres etc.). The point cloud contains a few standard landmarks of the head, also known as the 10-20 points for EEG/MEG experiments, and a contour scan of the head surface. The task is to register this point cloud based on the surface mesh of the head, and move the points right onto the surface at the registered position to set up the geometries for the subsequent modeling . At this point, we have only XYZ information of this point cloud.

The points together represent a 3-D shape or object. Each point in the data set is represented by an x, y, and z geometric Description. model = pcfitplane (ptCloudIn,maxDistance) fits a plane to a point cloud that has a maximum allowable distance from an inlier point to the plane. The function returns a geometrical model that describes the plane. This function uses the M-estimator SAmple Consensus (MSAC) algorithm to find the plane.

## This MATLAB function fits a sphere to a point cloud that has a maximum allowable distance from an inlier point to the sphere.

You should know or suspect a specific type of underlying equation like f(x,y)=a*sin(b*x+c)*exp(e*y)+g and you are searching the parameters a,b,..g which makes this surface best fit the cloud of points. "Metch", coined from "mesh" and "match", is a Matlab/Octave-based mesh/volume registration toolbox.

Point clouds provide a means of assembling a large number of single spatial measurements into a dataset that can be represented as a describable object. The pointCloud object creates point cloud data from a set of points in 3-D coordinate system The points generally represent the x,y, and z geometric coordinates of a samples surface or an environment.

## I have a 3D point cloud data (X [m]; Y[m]; Z[m]). And I want to calculate the value of some curvature (e.g. gaussian) in every point of the point cloud. Based on these curvature information I would select the points, that may belong to some geometric shape in the point cloud (e. g. to some planes, spheres etc.).

It has a high learning curve but it does almost Point Cloud Processing. Preprocess, visualize, register, fit geometrical shapes, build maps, implement SLAM algorithms, and use deep learning with 3-D point clouds. A point cloud is a set of data points in 3-D space.
