Dynamica is a plug-in for Maya that provides an interface to the Bullet rigid body engine. Bullet was originally created to simulate many rigid bodies quickly in a game context, but this plug-in helps extend its usefulness to film production. The Walt Disney Animation Studios used this plug-in to model the thousands of packing peanuts seen in BOLT.

Features of the Dynamica Maya plugin

  • Dynamica is cross-platform and works on Windows, Linux and Mac OSX
  • Dynamica runs on all versions of Maya.
  • Active, passive, and kinematic rigid bodies
  • Sphere, Box, Hull(convex), and Mesh(concave) collision shapes
  • Force breakable Nail, Hinge, Slider, and Six-degrees-of-freedom constraints
  • Frame based choreography control and simulation baking
  • The plugin exports to COLLADA Physics format and the native .bullet binary physics file format

It was used by Disney Animation and several other studios.

Vfxgal is a geometric algorithms library for the VFX industry. It contains a very fast and robust voronoi fracturer, as well as several other geometric algorithms (plane-clip, hull-clip etc). Vfxgal comes with Houdini11 bindings but has been written in such a way that minimal work is needed to bind to other frameworks.

PyODE is a set of open-source Python bindings for The Open Dynamics Engine, an open-source physics engine. PyODE also includes an XODE parser. PyODE does not wrap ODE’s API directly but changes it slightly to give a more Pythonic feel.

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 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…)
