Spectral rendering The core of Luxrender is fully spectral. Unlike traditional rendering software, which only operates on distinct colors (such as red, green and blue), Luxrender uses individual wavelengths. This allows LuxRender to correctly deal with wavelength dependent effects, such as dispersion, or accurately capture the color of incandescent lights. It also makes the rendered images look more natural.
I joined the EVASION team in september 2006 in order to work on real time rendering of natural landscapes as a whole. I'm interested in the animation and realistic rendering of terrain, atmosphere, ocean, vegetation, rivers, clouds, etc. I'm looking for real-time and scalable algorithms allowing users to navigate freely anywhere in very large landscapes (up to whole planets), from ground to space, without visible transitions.
This planet was by far the hardest for me to render properly. I've put together two different models of Earth; one is designed to be photo-realistic, and the other is designed after NASA's Blue Marble. Both models include optional night and city lights sections. These Earth models have been used in various productions by hobbyists and film groups. I've written a tutorial demonstrating how to build the models - you may find it here.
OpenDX is a uniquely powerful, full-featured software package for the visualization of scientific, engineering and analytical data: Its open system design is built on a standard interface environments. And its sophisticated data model provides users with great flexibility in creating visualizations.
The NASA Vision Workbench (VW) is a general purpose image processing and computer vision library developed by the Autonomous Systems and Robotics (ASR) Area in the Intelligent Systems Division at the NASA Ames Research Center. VW has been publicly released under the terms of the NASA Open Source Software Agreement.
Delny is a Python package which can be used to make a Delaunay triangulation from a set of n-dimensional points. It is effectively a Python interface to libqhull, the C library of the Qhull program, but (currently) restricted to Delaunay triangulation. It was first developed to use in a mesh generator developed as dissertation at the University of Southampton with Hans Fangohr as supervisor. This very specific application area was the reason for the limited functionality of the libqhull wrapper, which in turn is likely the reason that there is useable code available.
This is a release of a Camera Calibration Toolbox for Matlab® with a complete documentation. This document may also be used as a tutorial on camera calibration since it includes general information about calibration, references and related links.
JSatTrak is a Satellite tracking program written in Java. It allows you to predict the position of any satellite in real time or in the past or future. It uses advanced SGP4/SDP4 algorithms developed by NASA/NORAD or customizable high precision solvers to propagate satellite orbits. The program also allows for easy updating of current satellite tracking data via CelesTrak.com. Because this application was written in Java, it should run on almost any operating system or directly off the web using java web start!
