Run 3-D Demo online

Development and history

The embedded catalog classifies 3-D Demo as a Vectrex technical demo, credited to Chris (Mar 06 in 2000. Demo pages are kept separate from the playable Games collection so visitors can find music, visual experiments, technical work, tests, and utilities more easily.

This page groups 2 ROM editions under one stable URL instead of creating duplicate search pages for alternate dumps or revisions. The primary edition loads automatically; the other editions remain available in the in-app library.

This title is associated with the Vectrex 3-D Imager library. Vectrexia simulates the wheel-motor timing, index sensor, and CA1 synchronization needed for the cartridge to progress without the physical headset, while a normal monitor still cannot reproduce the spinning color wheel or stereoscopic separation.

Gameplay and background

Run 3-D Demo to explore its audiovisual or technical presentation. Some demo, music, test, and utility entries are passive, while others react to the Vectrex joystick or four action buttons.

How to play in Vectrexia

• Move with the Arrow keys or WASD. Compatible controllers can use the left analog stick or D-pad.
• Vectrex buttons 1–4 map to Z, X, C, and V, and to the standard face buttons on most gamepads.
• Press a controller button after connecting it so the browser can expose the gamepad to the page.
• Some demos are primarily audiovisual and may not require every movement or action control.
• For the original 3-D Imager games, Vectrexia simulates motor PWM, the active-low index sensor, and the VIA CA1 pulse so the program can run; the original stereoscopic color-wheel effect still requires compatible physical hardware.

Audio may begin after the first click, key press, or controller input because browsers can restrict autoplay.
