Some applications require that the rendering happens in real-time. Often, to model a planet, preexisting datasets, such as height and color maps of Earth collected by satellites, are used. However, sometimes the planet to be rendered is a fictive one without any preexisting data. This is when the datasets needed to render the planetary terrain have to be created, for example, procedurally. Highly detailed terrain, that covers the whole planet, requires a huge amount of data. That's why it would be preferable to generate and store only as much terrain as is necessary at given time. Also, great distances innate to planetary scale rendering bring challenges of their own. In this thesis we give some background to realtime planet rendering, explain a few methods applicable to planetary terrain generation, and describe problems arising from the huge distances and show some solutions to those. In addition, we present three slightly differing methods designed for real-time planetary terrain rendering that were developed as part of this research.", "language": "en", "element": "description", "qualifier": "abstract", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Submitted by Miia Hakanen (mihakane@jyu.fi) on 2019-06-06T08:55:37Z\nNo. of bitstreams: 0", "language": "en", "element": "description", "qualifier": "provenance", "schema": "dc"}, {"key": "dc.description.provenance", "value": "Made available in DSpace on 2019-06-06T08:55:37Z (GMT).
