Abstract

Scenery3d is a plugin for the open-source Stellarium planetarium application allowing users to freely observe and analyze 3D architectural structures under a realistic astronomical simulation, including realistic lighting and shadowing. During this project, we ported the pre-existing codebase (from 2012) to the current version of Stellarium, which required several structural changes like a change from Qt 4 to Qt 5 and a fully shader-based renderer. We also focused on improving the rendering performance and quality, and increased usability and code maintainability. Because a big feature of Stellarium is the use of non-linear projections which require more sophisticated rendering methods, several steps have been taken to increase the subjective performance of these methods to increase interactivity. For increasing the shadow quality, percentage-closer soft shadows were implemented. Finally, the plugin was made compatible with OpenGL ES 2.0, for use on embedded platforms or desktops without a suitable OpenGL driver.
