The image shows a recent screen-shot of the Ca3D-Engine that shows multiple players connected via a Ca3DE internet server and dynamic, per-pixel lighting with stencil shadows.
Ca3DE is an all-purpose, modern 3D graphics engine.
It 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.
Its main features include
high-quality, real-time 3D graphics,
a very powerful and flexible Material System,
cross-platform and cross-compiler portability,
multi-player network support,
physically correct lighting (radiosity based),
dynamic per-pixel lighting and shadows,
3D sound effects,
skeleton based model rendering,
very large terrain rendering,
and easy extensibility by scripts and MODs.
