Thomas deGroot is a long-time POV-Ray artist and Leveller user who finds imaginative ways to use them together.   Homeward Bound (800 x 450, JPEG, 67K) How it was made: The ocean: a Leveller heightfield (of course!) using an interference of two wavy terrains, followed by several passes of ridged multifractals and some Perlin noise.   The island: also a Leveller heightfield using diferent filters and finished with the Erode and Flatten Edges filters.   The ship: modeled in Moray 3.3. This took me about 4 months last year. It is a fairly exact copy of a VOC (Dutch East Indies Company) ship, based on the original building standards used at the time.   The seagulls: they were created by Mick Hazelgrove (and thanks to him for my using them) and appear in one of his later IRTC entries, The Preacher.   The scene was composed in Moray 3.3 and rendered in MegaPOV 0.7. One minor criticism is about the waves at the front. Due to the scaling of the heightfield, they appear somewhat blocky, but not too strange hopefully. Ancient Ruins (800 x 600, JPEG, 104K) A landscape of an imagined archeological dig. Leveller County Leveller 2.3 and POV-Ray 3.5 were used. In his own words: "Here is a scene using a lot of Leveller heightfields. "How was it made? Let's start in the background. The background mountain ranges are two heightfields, whose property is that they are extremely narrow compared to their length. This is to increase the impression of flattened perspective in the distance. The middleground and foreground are made up of two slightly different heightfields. The underlying one has it's higher grounds made sharper and slightly higher. It has its own rocky texture. Superimposed upon it is a smoother heightfield. This way, rocky ground seems to stick out of the turf, so to speak. The "turf" is obtained with the Grasstex include file by Rune Johansen. It makes use of a heightfield and its copy, slightly translated from each other in the Y-direction and with appropriate texturing. The impression of grassland is nice and renders very fast. "The water of the lake is another heightfield with a ripple effect. The large rocks supporting the tower are heightfields transformed by the UV-mapping feature of Leveller! "The small boulders in the foreground were made with Rockgen, but they were placed with the Veg plugin of Leveller, like the bushes. "Now the towers themselves: The basic octogonal shapes have been 'eroded' with... yes, eight heightfields! A ninth heightfield is responsible for the the ruined look of the top. They were placed in the landscape using Leveller's Markers export feature. So, all in all, eighteen different heightfields were used to create this scene. "Ah! The helicopters come from the Taschen edition of '500 3D-objects', volume 1 (2002); the bushes come from a macro originally made by Misha Riser; the 200 birds are by Neil Alexander; their random positioning was obtained by adapting a macro by Paul T. Dawson. All other features are my own."
