Documentation of heritage objects has advanced significantly with the invention and development of many 3D sensors and processing algorithms. These technical advancements are of the utmost interest for cultural heritage stakeholders; knowledge transfer between key players is therefore essential and is indeed the main philosophy behind the CIPA Heritage Documentation as an organisation. In this paper we present a report on the CIPA Tropical School in the Candi Sewu temple complex in Indonesia. Organisational aspects will be described, as well as some technical results of the workshop. As public interest in the tropical school was quite high, we argue that this type of limited participant training event involving international partners and cross-disciplinary experts is a very powerful tool in knowledge dissemination. Furthermore, we encourage the organisation of such events in other places around the world.
