Drive through the small town of Lipová with traffic, weather and a day–night cycle.

Quick start: T switches to the automatic gearbox, E starts the engine, F selects Drive, R selects Reverse (when stopped), W/S accelerate and brake, A/D steer. F1 lists every control.

CNA Street

A realistic, procedurally generated city street with traffic, pedestrians, shadows and reflections, rendered with CNA's extended graphics layer.

Note: it builds the street in your browser, so the first start takes about a minute. WASD moves, mouse looks, 1–8 jump between viewpoints, F1 toggles the overlay.

Living Room Simulator

Explore a furnished 3D living room with changing daylight and weather, rendered by the original C++ application through WebGL2.

Controls: WASD moves, arrow keys look around, 1–8 switch viewpoints, and F1 shows the controls. The first load downloads about 128 MiB of models.
