Planet of the Artichokes


This was the end product of some experiments using Kai's Power Tools to create terrain G2H maps. The embarassing thing is that I can't remember exactly how I did it. The steps were something like the following:

Create a 512 x 512 image in PhotoShop. Select the region 0,0 to 256,256 (use fixed-size marquee). Linear blend black to white in this region, black top-left, white bottom-right. Repeat (or copy) for the other three quadrants, so that the centre of the image is bright and the periphery dark. Select whole image, and apply Twirl filter. Press 'Q' for quick mask mode, and then do a radial blend from the centre of the image. Press 'Q' to return to editing mode, and fill the selected region with black. This should have the effect of suppressing the edges of the image (but because we built the mask with a blend, the transitions should be smooth. Apply KPT Video Feedback (Video) to the entire image, and save. Create a terrain in Bryce, edit it, and import the image to Bryce as a G2H map. Use 'Gaussian' to further shape the terrain.

Other KPT filters, such as Vortex Tiling also produce some interesting terrain maps.

The droplets of water on the surfaces of the 'artichokes' are spheres with the Mr Bubble water material assigned. These were raised above the terrain, and then dropped onto it using 'Snap to Land' (but it was still necessary to fiddle about a bit to give them more plausible landing positions).

Warning: nourishing artichokes are probably not found in the Namib desert. I made that bit up. If you are planning a trip to Namibia, you would do well to consider other sources of food.
