JPGFILE: kafka.jpg RENDERER USED: PovRay 3.02 (for DOS) TOOLS USED: POVLAB 4.0 SP1, sPatch 1.0, Lather 1.0, Moray 2.5, HF-LAB 0.84 RENDER TIME: 19 minutes 52.0 seconds (1192 seconds) HARDWARE USED: PC (Pentium Intel 200 Mhz/64 Mb EDO Ram) SCANNER (ScanJet HP 4P) IMAGE DESCRIPTION: Strange Dreamy Magical Kafka I really like the dreamy/non-sense/alienated atmosphere of this image! I know ray-tracing should be a lights triumph, but this image is an example of "carved lights"!! Consider this one the "dark angle of trace"!! This image is partially based upon an Environment installation i wished to realize in a little Art Gallery of my city (Rimini) in 1992, but the rental cost was too high for my possibilities. :( DESCRIPTION OF HOW THIS IMAGE WAS CREATED: (Main modeller) The main used program is the great Denis Olivier's POVLAB 3D modeller! (In order of creation) Kafka's Image Map - This photo is retrievable using any Internet Search Engine, and looking for "Kafka.gif". This seems the only Kafka's image available! Used as "Automatic_Square_Map" objects within POVLAB! Picture Frames - I've scanned a frame photo from a book; converted the TGA image in grey_scale; imported it in John P. Beale's HF-LAB 0.84 Beta (c) utility and smoothed/scaled to fit my taste. Used as "Heigh_Field" objects within POVLAB! Eyeballs - These are simple objects (each made by 3 spheres) i've created to simulate the very well-know 3DS eyeballs. ;) Used as "Sphere" objects within POVLAB! Apple - This is my first attempt on creating a lathe object. I used Klaus Lepschi's Lather 1.0 (c) utility, for its feature to export in POVLAB format. After having manually drawn the main shape, i decided to create a "cubic_spline" instead of "linear_spline", because it's better smoothed during rendering, but it creates a hole in the center of the object. So i've created also a "linear_spline" lathe object and scaled it a little. Putting the "linear_lathe" inside the "cubic_lathe", i've simulated a single object! The lathe slows down a lot the rendering time! :( Used as "Import Lathe" objects within POVLAB! Apple Twig - This is a simple curved spline created with POVLAB, using "smooth edges" feature. Used as "Spline" objects within POVLAB! Fabric - I used Lutz and Kretzschmar's Moray 2.5 (c) modeller (under the Apple) for its really great "Bezier Patches extended editor". Fast, easy to use and powerfull (imho). After having exported the patches to POV file, i've created manually (i.e. with an ASCII editor) the POVLAB Bezier import files. Used as "Import Bezier" objects within POVLAB! Hand and Arm - The "Hand" is a converted 3DS mesh i've found on the great graphic site <3D Cafe>. I've converted it in RAW format using Thomas Baier's 3Dto3D (c) utility; than generated different little raw files for every object (i.e. for every fingers), because i wanted to move indipendently those objects! The "Arm" (not really visible) is simply a "cylinder" object! Used as "Raw" objects within POVLAB! Curtains - This is my first object created with Mike Clifton's sPatch 1.0 (c) utility. It's a Windows 95 modeller for Bezier patches, that features a phong_shaded 3D preview (great!!). This object is "simply" a grid of patches with moved/scaled nodes - well, to say the truth, it's simply in the form, but it's composed by 104 patches (!!!!!), all manually converted in POVLAB Bezier import file -. :P Marco "tHe DReAMeR" Semprini
