DESCRIPTION OF HOW THIS IMAGE WAS CREATED: I remember various giant insects and spiders as monsters from when I used to play roleplaying games a lot, and the idea of a group of adventurers being attacked by giant spiders in the wilderness came from that. (And the Hobbit, of course....) After looking at so many pictures of fortresses while judging the previous round, I wished I'd done something like an evil mage's tower - so I quickly built one to use as a background object. Since it was done so early in the round, I had plenty of time to add more detail to it as more ideas occurred to me, so it's actually had more attention than many of the foreground objects :-( . The spider was modelled on a Pisaura mirabilis, a wolf spider from the section of the book that has details of arthropods that aren't insects. It's was modelled at about the right size, then scaled up to fight the adventurers. Posing spiders, each with eight separate legs to adjust, is a pain! The spiders would probably look Ok if they were larger in this image, but the adventurers wouldn't, so I went for this composition. Closeups of the two human vs spider "duels" are on my webpage at http://www.table76.demon.co.uk/POV/wip/wip_beasts.html anyway. The adventurers were in the Worship round, but have been posed differently for this round. They're facing away from the camera so you can't see how bad they look! I made hardly any progress with my newer version this round, so they're the same old humanoids I used in the Laboratory round. I tried making my own trees again, with better results than I've managed before. The main reason for doing this is the memory problems I've had in the past with better-modelled trees, such as those by Gilles Tran. My macro fills an array with values that describe the tree, and writes it to a file. It needs a lot more work still, but by copying and editing the definition in the file, I can make slightly different trees, which helps when I need this many of them. However, the trees still take up too much memory - I kept having to reduce the number of trees I was using. They work reasonably well in a forest, anyway :-) . I wrote another macro that scatters trees around, basically in a spiral, to avoid the problem I've found in the past, when I've wound up using offset rows of trees. This macro (woodland.mcr) also knows where the path is, and tries (too hard!) to make sure that no tree is planted on a path. I was intending to use MegaPOV to find the height of the heightfield for each tree's position, but the code that worked for me a few weeks ago no longer works - I'll probably realise why just after the deadline passes! The large spiderweb visible at one side is just a simple shape that has layered radial and onion textures. Technically, there should be one spiral thread, not concentric circles, but you can't see the web well enough for it to really matter. I had intended to include more objects, but since I had to reduce the number of background trees in order to include the tower and the adventurers, there didn't seem much point. I had to reduce the number of trees again when I tried to render a full 800x600 image (the official POV-Ray refused to do that; this entry was therefore rendered in MegaPOV). Next time, maybe I'll really look into level-of-detail to choose between high- and low-quality objects, which I didn't get round to this round.

No! My other entry had a 3Mb zipfile due to my not thinking, and including four PNG files, one of which was over 1Mb! The heightfield does use a PNG, but I learnt my lesson. No PNGs in this zipfile.
