ACM 9001 Orbital Computer ** ACM_MINI.GIF here ** The cover image was created by Doug Little using PovRay v3 on a Falcon. To enhance the "threatening" aspect of the machine, Doug borrowed HAL's glass eye. All of the text and logo detailing is geometric - no image maps were used. The component parts of the 3D objects were generated by hand or with the help of POV3's truetype 3D font support. The eggbox effect was achieved by repeatedly subtracting small spheres from a flat surface using a do/while loop - a new addition to POV3 for the programming oriented user. The planet was created using a custom map-like procedural texture - mainly shades of green, brown and blue with turbulent edges. POV3's atmospheric effects created the "emitting halo". Apart from the astronaut, which was scanned in from a book, the background was the only other part of the image not to be generated internally by POV3, and is the second of only two image maps. A Pentium PC was used to render the final iamge which took around 16 hours to render at 1030x1475, with adaptive antialiasing.
