<p>I&#39;ve done a talk at <strong><a href="http://gamelier.org/gaetan-renaudeau-on-procedural-vs-functional-rendering/">Gamelier</a></strong> last Monday about 
how to think the <strong>rendering</strong> in a more <strong>functional</strong> way.</p>
<h2 id="abstract">Abstract</h2>
<p>Most of today 2D graphics libraries restrict us to a set of primitive procedures (<code>drawRect</code>, <code>drawCircle</code>, <code>drawImage</code>,...) but when it comes to bring more interesting features you tends to be stuck with it. Let&#39;s see how we can just do things with a function of <code>(Vec2 =&gt; Color)</code>.</p>
<p>This is the way (<em>WebGL</em>) <strong>GLSL</strong> has already took and the presentation examples will be built on it.
Let&#39;s see what are the multiple benefits of taking that paradigm of rendering.</p>

This talk explains how to think the rendering in a more functional way. Let's see how we can just do things with a function of (Vec2 => Color).
