Similar to the previous renders, but with updated visuals, where the iteration count determines the colour from gold – through grey obsidian and to self illuminating red&yellow lava. A red point light without occlusion has been added at the centre of the mandelbulb to give effect of illumination from the lava below. Volumetric yellow fog is computed, where iteration count determines the density of the fog. The flight path has been smoothed using Catmull Rom splines after many suggestions over at fractalforums.com. Render time was 1:48 (hours) using a pair of ATI Radeon HD 5850s, but setting up the flight path took considerably longer.
