To populate real, ancient cultural heritage sites with low-cost, mobile virtual augmentations has been a demand from cultural professionals established long time ago. In this work we aim to address this demand by introducing three main novelties: a) employing an open, cross-platform mobile framework for 3D virtual character rendering & animation based on open standards b) for outdoors life-size augmented reality simulations c) and enhancing the performance of these simulations by introducing a geometric algebra animation interpolation method adapted for mobile devices.
