Dalai Felinto has been working on a Game Dome project for the last several months.
Dome Mode in Blender Game Engine.
This feature allows artists to visualize their interactive projects within anÂ immersive dome environment. In order to make it an extensible tool, we are supporting Fulldome, Truncated domes (front and rear), Planetariums and domes with spherical mirrors.
The support has been added to Blender 2.49. It uses a multipass texture algorithm as developed by Paul Bourke. Briefly, that involves rendering the scene 4 times and placing the subsequent images onto a mesh designed especially such that the result, when viewed with an orthographic camera, is a fisheye projection.
The project was started andÂ mainly sponsored by SAT – Society for Arts and Technology within the SAT Metalab immersion research program. Paul Bourke from Western Australia University helped with source code samples, general orientations and tests.
Benoit Boilsee reviewed the code, and helped fixing some bugs. Brecht Van Lommel helped with some related BGE bugfixes as well.
