<p>In computer graphics, parallel and perspective projections are the usual viewing methods to provide lifelike images. In fact, traditional rendering engines such as OpenGL and Direct3X only perform linear projection. But what if you need to generate distorted views? For example, we see a distorted environment when we look through a raindrop on a windshield. When we play computer games, we also might want to have a pair of ?magic? lenses that let us see a deformed virtual world.</p>
