This demo includes <span id ="helplightnum"></span> dynamic lights and <span id ="trianglenum">66450 </span>triangles. <br>
You are uisng <b><span id="is-webgl2"></span><span id="helpmode">Deferred Shading</span></b>.

<p>
This demo requires a decent graphics card and up-to-date drivers. If you can't run the demo, you can still see it on <a href = "https://vimeo.com/83616115">Vimeo</a>
</p>
<p>
<h2>Instructions:</h2>
<p>
<li>Modify number of lights in the scene:<span id = "range"></span> lights</li>
<input id="light-number-range" class = "slider" type="range" min="0" max="1000" step="5" width = "200px" onchange="showValue(this.value)"/>
<li>Drag mouse to view around the scene</li>
<li>w,s,a,d to move the camera</li>
<li>Press 1 to display depth texutre</li>
<li>Press 2 to display normal texture</li>
<li>Press 3 to display position texutre</li>
<li>Press 4 to display color texture</li>
<li>Press 5 to display ambient texture</li>
<li>Press 6 to display tile based deferred shading</li>
<li>Press 7 to display non tile based deferred shading</li>
<li>Press 8 to display NPR with tile based deferred shading</li>
<li>Press 9 to display debug view for tile based</li>
<li>Press 0 to display scissor test visualization</li>
<li>Press f to switch between deferred shading and forward shading</li>
