JPGFILE: mystery_.jpg RENDERER USED: MegaPov 1.0 for Windows TOOLS USED: Crossroads, PoseRay, Adobe Photoshop RENDER TIME: 07h 34m 56s (Parse 01h 59m 22s Photons 00h 51m 46s Trace 04h 43m 51s) HARDWARE USED: AMD Athlon XP 1900+ and 512 MB DDR IMAGE DESCRIPTION: You will find some impossible, mysterious things in this picture: - two suns - two worlds - in the 'upper world' snow is falling, but the tree has still leaves - in the 'lower world' the snow is not falling, although the two worlds are above each other - in the 'lower world' it's hot and tropical, in the 'upper world' cold and misty - in the 'upper world' a sign points to Atlantis DESCRIPTION OF HOW THIS IMAGE WAS CREATED: WORLDS: These worlds are height_fields with use of targa files, created with PhotoShop. The texture of the upper world is a lightly edited stone texture from stones.inc, the lower world's texture is a bozo color-map of different colors green and brown, combined with an image_map. WATER: These are simple planes with a water texture and photon mapping. I scaled the texture on the lower water smaller, to strengthen the feeling of the worlds having different dimensions. The little ship does also strengthen this feeling. TREES: For the trees I used Andrew Clinton's SplineTree macro(http://povplace.addr.com/files/). I wrote a macro that places trees upon the lower world heightfield, with the trace-function. The trees are randomly scaled and rotated. SNOW: I used Gilles Tran's snow macro for the snow lying on the upper height_field. The snow falling down is done with a simple macro I wrote, randomly placing white spheres in the air. Again, they are randomly scaled. FIRE AND SMOKE: The fire and smoke are spheres with media interior. At last, the scene uses radiosity.
