Brigks

Philippe Leprince — Tue, 28 Sep 2010 13:53:59 +0000

StudioNEST Brigks is a collection of kinematic solvers for Autodesk Softimage.

With StudioNEST Brigks you can build very efficient rigs that don’t require to setup overly complex object hierarchies. Since the source code of the kinematics solvers is provided, implementations of matching kinematic solvers can be achieved for other packages as well as standalone applications.

Wavelet Turbulence for Fluid Simulation

Philippe Leprince — Tue, 09 Feb 2010 15:57:38 +0000

We present a novel wavelet method for the simulation of fluids at high spatial resolution. The algorithm enables large- and small-scale detail to be edited separately, allowing high-resolution detail to be added as a post-processing step. Instead of solving the Navier-Stokes equations over a highly refined mesh, we use the wavelet decomposition of a low-resolution simulation to determine the location and energy characteristics of missing high-frequency components. We then synthesize these missing components using a novel incompressible turbulence function, and provide a method to maintain the temporal coherence of the resulting structures. There is no linear system to solve, so the method parallelizes trivially and requires only a few auxiliary arrays. The method guarantees that the new frequencies will not interfere with existing frequencies, allowing animators to set up a low resolution simulation quickly and later add details without changing the overall fluid motion.

This code is a reference implementation of our paper Wavelet Turbulence for Fluid Simulation. The code is intended as a pedagogical example, so clarity has been given preference over performance. Optimizations that inhibit readability have been removed, so the running times experienced will be longer than those reported in the paper.

Blender

Rob Bredow — Thu, 07 Jan 2010 04:33:56 +0000

Blender is an integrated application that enables the creation of a broad range of 2D and 3D content. Blender provides a broad spectrum of modeling, texturing, lighting, animation and video post-processing functionality in one package. Through its open architecture, Blender provides cross-platform interoperability, extensibility, a small footprint, and a tightly integrated workflow.

Aimed world-wide at media professionals and artists, Blender can be used to create 3D visualizations, stills as well as broadcast and cinema quality videos, while the incorporation of a real-time 3D engine allows for the creation of 3D interactive content for stand-alone playback.

Originally developed by the company ‘Not a Number’ (NaN), Blender now is continued as ‘Free Software’, with the source code available under the GNU GPL license. It now continues development by the Blender Foundation in the Netherlands.

Key Features include:

Fully integrated creation suite, offering a broad range of essential tools for the creation of 3D content, including modeling, uv-mapping, texturing, rigging, skinning, animation, particle and other simulation, scripting, rendering, compositing, post-production, and game creation
High quality 3D architecture enabling fast and efficient creation work-flow
User community support by forums for questions, answers, and critique at http://BlenderArtists.org and news services at http://BlenderNation.com
Small executable size, easy distribution

PyODE

Philippe Leprince — Wed, 06 Jan 2010 16:15:41 +0000

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.

Houdini Ocean Toolkit

Philippe Leprince — Wed, 06 Jan 2010 11:08:53 +0000

The HOT is a collection of dso’s and an OTL for rendering deep ocean waves using the algorithms of Jerry Tessendorf described in the SIGGRAPH 2004 course notes. The dso’s implement a SOP for displacing geometry and VEX functions functions for use in various Houdini contexts. The OTL contains a VOP that wraps the vex function.

Open Dynamics Engine (ODE)

Larry Gritz — Mon, 04 Jan 2010 23:23:41 +0000

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.

Field3D

Philippe Leprince — Sat, 02 Jan 2010 19:43:59 +0000

Field3D is an open source library for storing voxel data. It provides C++ classes that handle storage in memory, as well as a file format based on HDF5 that allows the C++ objects to easily be written to and read from disk. While the supplied C++ classes map directly to the underlying file format, it is still possible to extend the class hierarchy with new classes if needed.

The library was initially developed at Sony Pictures Imageworks as a replacement for the three different in-house file formats already used to store voxel data. It is the foundation for Imageworks’ in-house simulation framework and volume rendering software and is actively being used in production.
