            + stackgl is an open software ecosystem for WebGL, built on top of + browserify and + npm. Inspired by the + Unix philosophy, + stackgl modules "do one thing, and do it well". It is + easy to use parts of stackgl à la carte, and because it is written from the + bottom up, you can always drill down a layer. Unlike many 3D engines, + stackgl emphasizes writing shader code, and provides powerful tools like + glslify which bring the + modularity and productivity of npm to GLSL!

                + Before getting started with stackgl, you'll want to get familiar with + the basics of WebGL and GLSL. One place to start would be by trying out + one of our graphics-themed NodeSchool + workshops. Shader School and + WebGL Workshop are interactive and may be taken in any + order. +

                + +

                + Some other good learning resources include + Learning WebGL, + WebGL Academy, and + GLSL Sandbox. + + If you're particularly interested in shaders, you might want to out + An Introduction to Shaders or + Primer: Shaders. +
