This browser is not providing WebGL, so the simulators cannot draw.

Every page here renders its machine with three.js on a WebGL canvas. The page loaded, but the browser refused to create a 3D context.

• Open this same address in Firefox, where it renders correctly.
• In Brave, check brave://gpu. If WebGL is listed as unavailable or software only, turn on Settings, System, "Use graphics acceleration when available", then relaunch.
• If Shields are blocking it, set fingerprinting protection for this site to Allow all, or lower Shields for 127.0.0.1.
