VistaPro
Vista and Vista Pro are 3D landscape generation programs originally for the Amiga, Apple Macintosh and Microsoft Windows (PC) range of home computers. It was written by John Hinkley and its own About box describes it as "a 3-D landscape generator and projector capable of accurately displaying real-world and fractal landscapes."
Graphics Generation
Vista operates similarly to a ray tracer in that light paths are generated. The user specifies light sources, and camera angles. The ground may be colored to create different ground styles. Vista has water, tree and cloud effects, making some images almost photorealistic. The ground itself may either be generated from a random (or user inputted) number, or it may use DEM landscape files for real-world views, the software having come with a number of maps of Mars and Earth.
Vista can load and save output images in PCX, BMP, JPG and Targa formats. PCX files can also be imported as elevations and ground colors to allow third-party creation of landscapes in other image editors.
Trees can be placed on landscapes as either 2D or 3D objects. In 2D, the trees always face the camera and are fast to generate. 3D trees are created using fractals and can be given a variable bending of the branches to make them look more complicated.
Compatibility
The Amiga version of Vista works on all models of Amiga, however due to the low processor speeds generation of landscapes take a long time to complete. It was not unusual for a landscape generation to take several hours on a stock 68000 based computer. Later versions for 32 bit Amigas, an executable supporting the MC68881/68882 FPU is available, speeding up rendering considerably when such a chip is present.
The PC version runs in MS-DOS for the earlier versions and from 4.00 onwards it runs on all versions of 32-bit Microsoft Windows.
Popular Culture
Its most famous use was for the landscape used in the opening credits of The Chart Show. This sequence involved a silver spaceship flying through a series of valleys that had been generated using VistaPro (Vista didn't support generating animations until the Pro version was released). Vista was also used (both PC and Amiga versions) for the book by Arthur C. Clarke called "The Snows of Olympus", a picture book about terraforming Mars.[1]
