After opening the page, the optical experiment scene will be displayed, including optical elements such as light sources, prisms, and lenses. Light is dispersed and decomposed into a rainbow spectrum as it passes through a prism; it is focused or dispersed as it passes through a lens. You can drag the optical element to change position.

The whole process is purely front-end animation, based on Canvas 'ray tracing algorithm, which calculates the path of each ray in real time. Smooth interaction and accurate physics.

Suitable for being used as a physical teaching aid, popular science display or simply appreciating the beauty of optics. Its realization principle is the combination of Snell's law and geometric optics.

Optics Lab is an interactive visual effect based on Canvas in real-time rendering that simulates the refraction, reflection and scattering of light.
