In the WebGL canvas in this article, the user can visualize conic sections by altering the coefficients of the formula above the canvas. The conic section is shown for z = 1. Conic sections are defined by the quadratic form ax² + by² + 2cxy + 2dxz + 2eyz + fz² = 0. Aliasing is reduced by implementing rudimentary anisotropic filtering as discussed in …

For the lecture Image Synthesis at the TU München, I adapted the two algorithms shadow volumes and shadow mapping for the use in 2D scenes. In the canvas above you can test one of the two algorithms - shadow mapping. At first I implemented the two algorithms using C++ and OpenGL. Both make use of geometry shaders and layered depth maps for performant rendering. However, unfortunately neither of …
