TITLE: Weapon smith COUNTRY: USA (Originally the Netherlands) WEBPAGE: http://people.zeelandnet.nl/whhofman/jen RENDERER USED: Povray 3.5 RENDER TIME: 34:18 HARDWARE USED: Pentium IV 1.8 GHz TOOLS USED: * Adobe Photoshop 6.0 (to convert to JPG/PNG and to create one of the height fields) * WinZip (to create the zip file) IMAGE DESCRIPTION: Originally intended to be a torture chamber, I decided that a weapon smith might be a better idea. I decided to make the composition into an exhibit, as one of those example rooms in a museum. Some of the items are old, some of them were made specifically for this exhibit. On the wall is an example of something that would have been made here. The image should be complete, and it might therefore be fun to move the camera around yourself and look at items in detail or from a different perspective. DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I like programming all the objects myself in the POVRAY scene language, which I did again here. There were a number of issues, which are mentioned here with their resolution: 1. The walls. First I made them using a proper texture (bricks) but this didn't turn out very well. Then I tried to build the walls from separate stones. It worked quite well up to a certain point, but the result didn't have a really old feel to it. So I decided to create a wall using a height field. Placing the height field was a bit tricky as well, but once I managed to do this, it looked quite well. I tried various texture types, and settled for the current one because of the nice reflections of the fire on it. One wall was kept in brick form, to indicate the wall that the museum would be on (you can see this wall in the reflection on the hood). 2. The anvil. Probably the most complex CSG that I made. It took quite a few hours to get everything right. 3. The old wood. The default wood textures of povray were insufficient, especially because one would expect soot and burn marks on it. This is why I changed them accordingly. 4. This is the first image that I made using radiosity. I tried other raytraces with it, but it usually made things worse. In this case, however, it made everything stand out better. As with my other raytraces: the sharp shadows are intentional.
