On some computer hardware Internet Explorer 11 is not able to use the GPU (graphics processors) to do graphics acceleration. JavaScript Advice Use JSLint Have excellent test coverage Use the Chrome and Firefox debuggers JavaScript Build Pipeline See Concatenate Minify Different than C++ Goal : fast downloads Common: Alternative: fine-grain modules How do you deploy shaders?. WebGL Create an animation loop: ( function tick() draw(level) // Just works WebGL The rest is similar to desktop OpenGL: //.
