This application demonstrates the rendering of the Mandelbrot Set using the OpenGL Shading Language and the EXT_framebuffer_object extensions. The demo allows the user to increase/decrease the number of iterations and to change the visualization (Iteration Based or length based). GLSL Fragment shaders compute the iterations, then the results are rendered to a texture. The next pass continues with the computation of the iterations using the previously rendered texture. This process is repeated until you like the results. In the last pass the complex number is visualized by using look up tables or the length.
