Mesh Unfold

This submission is based on Alexandre Gramfort's "matlab-mesh-to-pdf-with-3d-interactive-object". His program allows meshes to be converted into 3D PDF figures. However, his code only allows a single layer to be converted, and does not enable transparency.The present submission does not create...

This function uses a vectorized version of the marching cubes algorithm to compute a triangulated mesh of the isosurface within a given 3D matrix of scalar values at a given isosurface value. The output is a triangulated mesh specified in terms of a face list and a vertex list. The orientation of...

Simple function that tells if a point is inside of a mesh, be it concave or convexThe algorithm just finds the intersection points between the facets and a vertical line that passes through the original point. Depending on the relative position of the intsersection points and the facet normals it...

This function calculates the principal curvature directions and values of a triangulated mesh. The function first rotates the data so the normal of the current vertex becomes [-1 0 0], so we can describe the data by XY instead of XYZ. Secondly it fits a least-squares quadratic patch to the local...

This is an implementation of exact geodesic algorithm for triangular mesh (first described by Mitchell, Mount and Papadimitriou in 1987) with some minor improvements, extensions and simplifications. The algorithm has O(n^2 log n) worst-case time complexity, but in practice can work with...

USAGE===== This function enables a 3D array to be displayed using a patch surface mesh. To plot a 3D logical array, the function is called using the following syntax: >> hpat = PATCH_3Darray(gridINPUT,gridX,gridY,gridZ); Alternatively, a 3D numeric array can be plotted such that the colour of...

Converts a regular mesh defined by X,Y and Z into a regular triangulation. The output is patch data (triangles) in the faces d-deDUFd-deDt and vertices d-deDUVd-deDt format. The quadrilateral mesh faces are converted to triangles by splitting the faces into triangles according to the setting...

This function MESH2TETRA converts a triangulated surface mesh into a tetrahedron volume mesh. Main advantage above existing constrained 3D Delaunay is that it will never add new boundary points, (useful for active appearance models) Disadvantage, some highly non-convex surface-shapes cannot be...

These files features a complete software render pipeline from Triangulated Mesh to Fragments. Like the OpenGL software renderer, but without using any external libraries, and far less code. The renderer renders to a Matlab image, instead of the computer screen.The render pipeline is written in...

The X, Y and Z matrix arguments can be used exactly as in the surf and mesh functions. But attention to the colors, because DXF fiels do not uses RGB palete. Instead they use a scaled color palete between 0 and 255.

One of the major drawbacks of matlab is the lack of a way of changing the viewpoint of a 3D mesh using a natural (arcball) interaction.In this simple function I demonstrate the arcball interaction allowing a 3D sphere to be moved naturally. Run the function and drag and drop with your mouse on...
