Calibration and warping for fulldome projections

This ongoing project aims to create a suite of tools for easy camera based multi-projector calibration for fulldome type environments. The project is specifically aimed at 3D simulation output that needs to be rendered, warped and blended for correct output across multiple overlapping projectors. No projection "server" is required and the simulation software can render directly to the projectors involved therefore ensuring the highest possible image quality. Although domed projection surfaces are targeted initially, the approach can be used for different shaped surfaces provided the basic geometry of the surface is known.

Black Shoals Stock Market Planatarium

A real-time stock market data driven planetarium conceived and developed by the artists Joshua Portway and Lise Autogena. Thousands of companies from across the world are represented as stars that flicker and glow in as shares are traded on various stock exchanges. The brightness and duration of the glow indicates the volume of the trading activity and the stars slowly drift in response to the complex movements of capital in the markets.

This installation was exhibited as the main installation at the Nikolaj contemporary art gallery, Copenhagen in Spring 2004 and again as part of the Big Bang Data exhibition at Somerset House, London in 2015 and again at the Art Science Museum in Singapore in 2016.

Most Blue Skies

Most Blue Skies is a computer generated installation by Joshua Portway and Lise Autogena that attempts to find "the bluest skies" in the world.
