Wander forever
Tundra is a real-time 3D procedural world renderer built with a custom software rasterizer. Explore an infinite frozen landscape featuring dynamic weather, realistic terrain generation, and atmospheric lighting effects. The engine renders everything from scratch using CPU-based rasterization, creating a unique visual style reminiscent of early 3D graphics with modern procedural generation techniques.
The world generates seamlessly as you move, creating vast tundra landscapes with rolling hills, frozen lakes, scattered trees, and falling snow particles. Experience the passage of time through a dynamic day/night cycle that transforms the atmosphere from deep blue dawn to bright noon, warm dusk, and dark midnight.
