ANN

January 6, 10 //

ANN – Approximate Nearest Neighbor Searching – is a library written in C++, which supports data structures and algorithms for both exact and approximate nearest neighbor searching in arbitrarily high dimensions.

In the nearest neighbor problem a set of data points in d-dimensional space is given. These points are preprocessed into a data structure, so that given any query point q, the nearest or generally k nearest points of P to q can be reported efficiently. The distance between two points can be defined in many ways. ANN assumes that distances are measured using any class of distance functions called Minkowski metrics. These include the well known Euclidean distance, Manhattan distance, and max distance. (more…)

GTS

January 6, 10 //

GTS stands for the GNU Triangulated Surface Library. It is an Open Source Free Software Library intended to provide a set of useful functions to deal with 3D surfaces meshed with interconnected triangles.

The code is written entirely in C with an object-oriented approach based mostly on the design of GTK+. Careful attention is paid to performance related issues as the initial goal of GTS is to provide a simple and efficient library to scientists dealing with 3D computational surface meshes. (more…)

Bullet Physics

January 5, 10 //

Bullet 3D Game Multiphysics Library provides state of the art collision detection, soft body and rigid body dynamics.

  • Used by many game companies in AAA titles on Playstation 3, XBox 360, Nintendo Wii, PC and iPhone
  • Modular extendible C++ design with hot-swap of most components
  • Optimized back-ends for pthreads/Win32 Threads multi-threading and PS3 Cell SPU
  • Preparation for OpenCL data parallel optimizations for upcoming Bullet 3.x
  • Discrete and continuous collision detection (CCD)
  • Swept collision queries
  • Ray casting with custom collision filtering
  • Generic convex support (using GJK), capsule, cylinder, cone, sphere, box and non-convex triangle meshes. (more…)

Open Dynamics Engine (ODE)

January 5, 10 //

ODE is an open source, high performance library for simulating rigid body dynamics. It is fully featured, stable, mature and platform independent with an easy to use C/C++ API. It has advanced joint types and integrated collision detection with friction. ODE is useful for simulating vehicles, objects in virtual reality environments and virtual creatures. It is currently used in many computer games, 3D authoring tools and simulation tools.
