Lumina is a 3D game creation environment built around LumenLang. It combines a visual block-based editor with traditional programming, letting you create interactive 3D projects either visually, through code, or by mixing both.

Lumina provides a 3D workspace for building levels, placing and configuring objects, and creating gameplay logic. Its visual programming system supports variables, conditions, loops, mathematics, movement, physics, input, collisions, and other game functionality.

For programmers, Lumina integrates LumenLang, a custom programming language compiled to bytecode and executed by its own virtual machine. This allows projects to use the same language and runtime both inside and outside the visual editor.

Lumina is open source and released under the GNU GPLv3 license.
