<GeeXLab Features/>

Free and Cross-Platform

Code once, deploy on several platforms

GeeXLab is a free standalone application for desktop operating systems. Just download it and use it. GeeXLab is available for Windows 32/64-bit, Linux 64-bit, macOS, Raspberry Pi and Tinker Board.

Lua, Python and Shading Languages

Only popular programming languages

GeeXLab supports both Lua and Python as main languages for demo coding as well as GLSL (OpenGL and Vulkan) and HLSL (Direct3D 12 -- Windows 10 only) for realtime shader programming. Lua and Python can be used at the same time in a demo. Some scripts can be coded in Python and others in Lua. It's up to up to mix them as you want. Lua, Python, GLSL and HLSL can reside in separate files or in a single XML file that acts as a hub (or container) for all scripts.

Simple to Use

For Budding Graphics Developers

Here is, in few words, how GeeXLab works: a demo is essentially made up of one or several initialization scripts (Lua and/or Python) and one or several per frame scripts (Lua and/or Python). Initialization scripts are executed once at the beginning of the demo and frame scripts are executed every frame.

What's more, GeeXLab is IDE agnostic: just use any text editor to edit the source codes of a demo. Simplissimo!

Low Level Programming

For Graphics Hackers too!

GeeXLab does not include a game engine that takes the control over your logic. GeeXLab offers a low level API (don't panic, no assembler here) that lets you free to manage your logic and rendering code as you want. You can even code you own dynamic libraries (in C/C++ for example) and load them in Lua and Python scripts.
