Carsten Fuchs has released an updated demo of
Ca3D-Engine, a modern 3D graphics engine which can be used to create a variety of 3D applications, including games, simulations, and training and architectural software. The development kit is freely available, and the DeathMatch MOD code is open-source. The latest version introduces a new GUI Editor, a convenient graphical editor for editing GUIs for use in Ca3DE. The resulting GUIs can be used both in 2D (e.g. for the console, player HUD or the main menu) as well as directly in the 3D worlds as game elements. Visit the official
website for details.
