Four Issues To Consider When Producing Fulldome Content for Wide Distribution Brad Thompson – Lead Animator Spitz, Inc. Creative Media
Producing Fulldome ContentFor Wide Distribution • Nominal Camera Tilt • Action and Text Safe Areas • Gamma • Star Decimation
Test Theaters • Franklin Institute Fels Planetarium 4 Channels 1280x1024 Wavelet Compressed Video, Partial Dome, CRT Projectors, 0 degree tilt • Denver Museum of Nature & Science 11 Channels 1280x1024 Wavelet Compressed Video, DLP Projectors, 25 degree tilt • ElectricSkyII at Spitz, Inc. Single Lens Fisheye, 1536x1536 Uncompressed Video, 12 degree tilt • SciDome at Spitz, Inc. Single Lens Fisheye, 1024x1024 compressed Video, 10 degree tilt
Nominal Camera Tilt • Visible Horizon • Non-Visible Horizon • Implied Horizon • Rolling Text Plane
Nominal Camera Tilt • 00 Degree Tilt • 10 Degree Tilt • 20 Degree Tilt • 30 Degree Tilt
Action & Text Safe Area Out of View Periphery
Gamma/Color Consistency • 2.2-2.5 Gamma • White Point - 6500 Kelvin
Gamma/Color Consistency • Lack of understanding • Too many projectors to calibrate • Cost of calibration hardware • Adjustability of projectors • Image is percieved as less bright
Star Decimation • 4 pixel stars hold up well • Filtering methods yield comparable results on non-moving images. • Higher Magnitude (dimmer) stars vanish • If the starfield is the main subject of the show, more care should be taken.
