One of the great headaches of developing interactive graphics applications for online deployment is covering every base. Your targets likely include a near-infinite combination of browser vendors, browser versions, and graphics hardware. The Khronos Group created WebGL to slice through this Gordian knot, rendering high-performance interactive graphics in any compatible browser, and on any graphics processing unit, without the need for plug-ins. Now, with support for WebGL 2.0 in Safari 15 for both macOS and iOS, we’re happy to report that “compatible browsers” includes pretty much all of them.
