Concave Polygon

LWKT is designed as an Open Source, handy and accessible WKT parser. LWKT is able to support point, multipoint, linestring, multilinestring, polygon and multipolygon. Now you can make use of this handy tool to improve your development process. Platforms: Windows

CON2VERT - convert a convex set of constraint inequalities into the set of vertices at the intersections of those inequalities;i.e., solve the "vertex enumeration" problem.V = con2vert(A,b)Converts the polytope (convex polygon, polyhedron, etc.) defined by the system of inequalities A*x = n (m... Platforms: Matlab

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 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

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

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

This is Brand new so please advise-me if problems occurs.Here you can find an m-file with three different algorithms for inpolygon test.Depending on the input data, the one that is extimate to be the best will be chosen.This version do not support the onpolygon output so tollerance is not...

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... Platforms: Mac

geo-utils contains two helpful utility functions: 1. Point-in-polygon test 2. Random point generator. Right now it performs better if the polygon covers a large portion of its bounding box. The test is performed using this algorithm. 1. Generate a bounding box 2. Generate a random point... Platforms: *nix

GLC_lib is a C++ library for high performance 3D application based on OpenGL and QT4 GUI. Some GLC_lib features : Supported file format : 3DS, OBJ, COLLADA, 3DXML, OFF, STL. Easy view manipulation, Level of detail, shaders... Feature list : Built in 3D view manipulator (Track Ball, rotate... Platforms: *nix

OpenGL::PLG is a class for OpenGL polygon objects. It lets you easily create and manipulate 3d polygon models. It also reads and writes files in raw PLG format, dumps OpenGL code and renders the 3d model (if you have Perl OpenGL installed). Platforms: *nix

Pogolyn is a cross-platform 3D graphics engine intended to be easy-to-use and high performance, which also supports the features for game development, such as animation, input device handling and sound playing. Features Polygon and sprite rendering with scene graph Transparent objects... Platforms: *nix
