GEO is a C++ geometric template class library. Use this library for your graphical, image processing, or scientific applications. It has a rich set of operations with vectors and matrices, 2D and 3D objects (such as finding convex hull and bounding box), triangulation, tesselation, etc.
Terrain Generation is a program designed to produce realistic elevation maps. Various methods are used to simulate faulting, rain, and gravity erosion. There is also a 2D cos transform that can be used. The program currently saves terrain as a Wavefront's Advanced Visualizer Object file (.obj).
Mathnetics is an API for creating advanced, interactive, Web-based mathematical applications. It defines various important mathematical objects that are inter-related and on which many numerical calculations can be done. It also features rendering of 3D objects onto an SVG canvas (to do so, it includes certain utilities such as browser sniffing, DOM node selection, and DOM readiness detection), which is quite robust. A few basic 3D objects are given (Line, Sphere, Cube), but the user can define any 3D object desired as per the specification.
Polymul is a self-contained C++ template library for efficient multiplication of multivariate polynomials. It is intended for low order polynomials of a few variables, but is in principle limited only by the compiler's maximal template recursion depth. Polynomials can be created over any scalar type, such as integers or double precision floating point numbers.
safe numerics provides safe integer operations for C++ integers. Arithmetic operations in C++ are not guaranteed to yield the correct mathematical result. The feature is inherited from the early days of C, when the behavior of int, unsigned int, and others were designed to map closely to the underlying hardware. These types can silently overflow or change sign. This library contains drop-in replacements for the standard C types which throw exceptions whenever invalid operations occur.
