3D Modeling Has Arrived! It’s Cheaper! It’s Better! It’s Faster! Pick all three! Things Have Changed Instructional technology is more accessible and affordable to the scientist as an “artist” Interface design has improved You don’t need to be a “unix nerd” anymore   top

Costly and Complex Alternatives Soft Image (Microsoft) Kinetix 3D Max (AutoDesk) ER Mapper Scientific Visualization (AVS, Data Explorer) Terrain Explorer TERRA

top For Some Things There’s A Cheap Alternative... Bryce!

top It Works Well At Any Scale You Like! The following set of images are all part of the same world, the first within the second, the second within the third, and so on...

Image 1: Rocks on a table Image 2: Desert Home Design Image 3: Terrain model of SDSU and surrounding area with aerial photo as texture Image 4: Large scale terrain model with topo map as texture Image 5: The Home Planet

top A Practical Application Create a 3-D terrain in Bryce ® from a Digital Elevation Model (DEM) and overlaid aerial photo to create a fantastically realistic world. Step 1: Download DEM using TFMAKE from Truflite Use our step-by-step online tutorial for Step 1. Step 2:Create A Grayscale Bitmap from downloaded DEM. Use Photoshop ® or other Image Editor to align Grayscale “DEM” with bitmap image of topo map or aerial photo.

Step 3: Convert Grayscale Image to “DEM” Using Bryce ®

Step 4 (optional): Overlay ATopographic Map

Step 5: Overlay An Aerial Photograph

top Another Application: An Interactive QuickTime VR Movie Create a QuickTime VR Panorama with Bryce ®

top A Final Application... A Volcano Erupting

For the Future... Buy Bryce ® ($149 at Aztec Bookstore) Keep an eye on MetaCreations Share your results with your peers
