JPGFILE: iridium.jpg RENDERER USED: POV-Ray 3.1g TOOLS USED: hamaPatch 2.1, TextureView V3.42 RENDER TIME: 17h 16m 45s HARDWARE USED: P3-550E, 128MB RAM, ATA/66 HD IMAGE DESCRIPTION: Archangel Radiant swoops down from Heavens to meet his grim adversary at the gates of Hell. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: Every single object was modeled with the use of Hama Patch 2.1, which is, by the way, an excellent program. Even though it's still buggy and unfinished it offers considerably more than sPatch, and since version 2.1 features texture editor that certenly made my life easier. Origato Sensei !!!!!! There were three major objects in the scene: demon, angel and the cave, that were modeled separately and then put together. About Demon: It's my own creation from tip to toe. I call it a generic monster. It has all the features one would expect in a demon, a gargoylish stature, a grining-large-teeth glowing-eyes face, spikes, dragon wings, a tail and last but not least a very large sword. Construction of demon was considerably the most time consuming, because I was still getting familiar with the modeling program and because I was doing it from the scratch, so sometimes I had to wait for an inspiration. There's not much to say about the techique of modeling. Basically I just visualized a cross section of a part and extruded it in 3rd dimension. After a few extrusions I clay-modelled the object point by point until I got what I was looking for, or something similar. There are 46 seperate parts that make up the demon. After reaching a conclusion that the red-skin-black-spikes demons (like Diablo) was a bit worn off style I decided to make the skin look like stone as every self respecting gargoyle should have and the spikes naturaly white like polished bone. Red glowing eyes are just red diffuse 1 ambient 1 globes, that are transparent and inside of each is a red point light with fading. This is a trick I use to avoid the use of media for halo to simulate glow. About Angel: Anyone familiar with Magic the Gathering card game would probably recognize this angel as Archangel Radiant (it's a she apperantly). I used those cards I could find that fetured a picture of Radiant to make the modeling easier. There are several versions of Radiant however, as each artist made his own interpretation, so my version is sort of like a meld of those. The angel's wings still look a bit artificial, but there is a reason for that as I will mention later. There are 41 sperate parts that make up the angel. The armor was supposed to be gold and the suit was supposed to be chain-mail-like. To texture the suit I used a scaled down bumpiness and a crand feature. However after anti-aliasing it turned out a bit to smooth, so I pretended hat it does look like a chain mail and imedietly felt better. About Cave: It took about 5 minutes to do the cave. It's quite plain and simple. Features a stone bridge. About the scene: After using the dummy objects to position the characters I experimented with the lighting. The whole scene has a built in scattering media and seven spot lights that interact with it. These spot lights make the rays of light that shine on and around the angel. There are three more area lights that don't interact with media and cast soft shadows. Now I know why they need hundreds of SGI machines to render those rather simple looking cartoons: As I mentioned earlier, the angel's wings look a bit artificial, but in order to make them look natural they would require more layers of feathers, and since I made feathers as objects, the wings made up for almost 50% of the number of bicubic patches in scene. Now... bicubic patches are such a nice feaure for spline modellers, but there is a catch. Every patch must be descrambled into a large amount of triangles by the renderer. After seeing the POV-Ray reporting that the last test render used up almost 600MB of free memory and parsing lasted for well over 12 minutes I deceided to leave the angel's wings as they are and make a dummy objects to ease my tests with lights and save my nerves. No source? But why? I truly regret that I was not able to provide people with source files. It is not because I don't want to share, but because the size of it is considerable. But if you really want it send me an empty CD-R and I'll send it back to you with the source. OK enough with the jokes. The source files (angel.inc, demon.inc, cave.inc, scene.pov, scene.ini) take up almost 8.3MB so it would be a real waste of my time and someone's drive space if I had sent it.
