13<H2>Description</H2>
14<P>The purpose of this demo is to encourage developers to explore the vfilter (vertical filter) and customize the vfilter settings of their own game instead of using the default settings defined in each <a href="../../Framebuffer/RenderMode.html">render mode</a>. In this demo, you can control vfilter settings to adjust flicker and brightness of the output image. You can start making adjustments using pre-defined settings from each available <a href="../../Framebuffer/RenderMode.html">render mode</a>.</P>
15<P>To enhance jaggies in the scene, the texture on the octahedron is animated with different line width textures by the timer.</P>
