Open Wonderland

Open Wonderland is an open source tool for creating three-dimensional worlds, where multiple users can collaborate in creating interactive environments, and communicate via text or audio.

The program, which has a fairly simple to use interface, allows 3D environments to be created in a very simple but very customizable way. This means that, for example, you can perfectly recreate the most emblematic streets or squares in your city, from just a few pictures.

One of the most interesting features in this application is the chance to communicate with other users through voice calls. That way, you can coordinate a project perfectly between several users.

Open Wonderland is a 3D authoring tool with many advantages (aside from its ease of use). For one, it is based entirely in Java, so you can use it on any operating system. And for another, it has a huge amount of tutorials which are of invaluable help.
