Check out this website. These are REAL 3D models of Terrain Draped data- converted to a special process Solid Terrain Modeling has developed. Look for the STUNNING HUGE and HI-REZ model of the Virunga Mountains displayed in National Geographic museum (STM website). Terrain Draping is already widely used in the scientific-geographic communities- as well fairly widely supported in free programs like MicroDem, 3DEM, etc. (However- not at the quality of Vue, Bryce raytracing, etc.) You most often see Terrain Draped models in National Geographic magazine. I think there is a real potential market for Vue, Bryce, Terragen users for Pre-Set UP Terrain Draped models of the Grand Canyon, Mt. Saint Helens, etc. etc. The Ray-Traced results are VERY IMPRESSIVE. And of course in VUE- you can even add Eco-Terrains so that your Mt. St. Helens scene has a few Million Fir Trees. It LOOKS so REAL!!!- but most people don't want to figure out the steps involved- which require precise alignment in Photoshop to the DEM Terrain. (Geo Software uses UTM coordinates- but unfortunately VUE, BRYCE, Photoshop etc. don't recognize GeoTIFF files). BTW- I read your piece about working with Bryce developer Kai Krause. Because I was an early publisher of VistaPro Scenery on CD ROM back in ancient times- the MetaCreations (actually I think it was still HSC software then) asked me to supply the Bryce Canyon DEM they used for the cover of the manual. So that's my tiny little claim to fame!)
