realXtend is an open source technology and platform for developing hybrid reality multi-user virtual environments. It is a de facto standard for avatar-based online interaction and building of 3D Internet.
LudoCraft has been an integral and central part of the realXtend Core Development since the beginning. We have created the realXtend core itself and expanded on it via multiple other projects, such as Avatar 2.0, Meetius and FI-Ware. realXtend is in a continuous state of ever progressing development and we are along the ride.
