Convex Polygon

It can be used in image recovery actions, image processing tasks, in signal processing, in simulations or optimization tasks. Requirements: - MATLAB 7.5 or higher Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

It works similar to the fill command in MATLAB.It allows multiple overlapping hatching on different polygons, and can even be used to obtain a speckled affect. It has a fair number of options for different line styles, colors, widths, and background colors Requirements: - MATLAB 7.4 or higher... Platforms: Windows, Mac, *nix, Matlab, BSD Solaris

SharpConstruct is a 3D modeling program that paint depths on to polygon models in real-time. Unlike traditional modeling programs, SharpConstruct makes it easy to model organic shapes. There is no need to even look at a wireframe (unless you want to). Instead, the model is manipulated much like... Platforms: Windows, *nix, C/C++,

InPolyedron detects points inside a manifold closed surface (even non convex ones). The normal orientation is assumed to be outwards. Warning there is no check for closed surface or normal orientation, open surfaces will give nonsense results.In the limit of numerical accuracy, points lying on... Platforms: Matlab

The script quasi_newton_dfp.m optimizes a general multi variable real valued function using DFP quasi Newton method. During the iterations if optimum step length is not possible then it takes a fixed step length as 1. For the theory any good book on optimization techniques can be consulted. This... Platforms: Matlab

Intended for 3D geological/geophysical visualisation of layered data and will eventually form part of a geophysical visualisation package.Run ThreedDemo to get an idea of how to use. INPUTS: LayerN: The number of the layer to be plotted R: a m*n*k matrix of colour/resistivity data for each layer... Platforms: Matlab

The script steepestdescent.m optimizes a general multi variable real valued function using steepest descent method. During the iterations if optimum step length is not possible then it takes a fixed step length as 0.001. For the theory any good book on optimization techniques can be consulted.... Platforms: Matlab

(1) CubicBezier1.m : Evaluates Cubic Bezier Curve for given four Control Points and interval.(2) PlotBezier1.m : Plots Bezier Curve, Control Points, Control Polygon(3) TestCircleApproxByCubicBezier.m : Test Program. Pass Control Points that approximate unit radius circle using cubic Beizer... Platforms: Matlab

GloptiPoly is a MATLAB/SeDuMi add-on to build and solve convex linear matrix inequality (LMI) relaxations of the (generally non-convex) global optimization problem of minimizing a multivariablepolynomial function subject to polynomial inequality, equality or integer constraints.The software... Platforms: Matlab

The Matlab convhulln is a gateway to the quickhull algorithm ( see www.qhull.org ). In my opinion, one weak point of this mex routine is that it processes all the points without performing any preliminary filtering.In many cases it would be faster if only the point that can be part of the... Platforms: Matlab

This script may be easily converted to a function which could be an extremely useful subroutine in optimization problems to check whether the objective function is globally convex. It may also be used to derive the expressions for gradient and Hessian of the given multidimensional real valued... Platforms: Matlab

This builds a navigation GUI for navigating n-dimensional convex Pareto surfaces interactively. It requires linprog from theoptimization toolbox, but can probably be replaced easily with a free version. The linear programs solved during navigation are very small and easy. It is assumed that all... Platforms: Matlab

In large scale mapping projects with numerous satellite images, it is useful to have a vector file depicting the boundary of the images. This script when run from the folder containing the images, it automatically detects the geotiffs and extracts their image area boundary and constructs a... Platforms: Matlab

Gmap_geo provides a Google Map location picker widget for Geo point fields and a Google Maps-based output formatter for point, line, and polygon fields.HOWEVER: Gmap_geo was written for an earlier iteration of the Geo module. It has not been updated to use recent Geo API changes. If you are... Platforms: PHP

ShapeKit is a geometry library for iOS that aims to bridge GEOS with Apple's MapKit. Features * ShapeKitGeometries are standard cocoa objects ShapeKitPoint *myPoint = [[ShapeKitPoint alloc] initWithCoordinate:CLLocationCoordinate2DMake(0, 0)]; * ShapeKitGeometries have standard MKShape...

This is the home for the humble stress_driver stress test tool that began life by crashing Convex supercomputers. Platforms: Mac

QMGA is a Qt-based molecular graphics application for visualizing large ensembles of ellipsoids, spherocylinders or spheres. It is conceived for coarse-grained mesoscopic molecular simulation, but can be used for any kind of convex body systems. Platforms: *nix

GeoCalculator, the new latest thing in geometrical math. GeoCalculator is your one stop for solving any geometry-related equations. Features such as Triangle Solvers, Polygon Finders, and TONS of equations lets you solve ALL equations that you need. Platforms: *nix

simplekml is a python package which enables you to generate KML with as little effort as possible. At the time of making this package nothing was available (at least I could not find anything) that could create KML files easily. You needed a lot of bloated code to even create a simple point....
