Optimal camera path planning for 3D visualisation

Virtual cameras motion is crucial to properly lay out virtual scenarios on the screen. Despite the wide range of camera path planners, none have yet reached realism. In this work, we propose a novel camera path planning algorithm that generates accurate camera attributes continuously in time. Based on a set of known viewpoints, our solution computes a curvature-minimising path that optimally links keyframes. The computation of the linking segments is based on Pythagorean Hodographs (PH) interpolation technique. The result is a smooth and informative camera motion that in turn conveys the events of 3D scene faithfully.
