Artist, L.J. Altvater, has created stunning 3D images with Persistence of Vision Raytracer. Some of the images are pictured below. In 2D, they seem static and flat, but when viewed in 3D, their entire appearance changes. The backgrounds bend and come forward, the relationship between objects is seen and so much more visual information is available. What a dramatic difference!
Persistence of Vision Raytracer is a high-quality, tool for creating three-dimensional, photo-realistic images using a rendering technique called ray-tracing. It reads in a text file containing information describing the objects and lighting in a scene and generates an image of that scene from the view point of a camera also described in the text file. Ray-tracing produces very high quality images with realistic reflections, shading, perspective and other effects.
A NOTE FROM THE ARTIST:
My background is in painting primarily but my interest in stereo images found an outlet in 3D computer graphics. I've been using the Persistence Of Vision Raytracer (POV-Ray, freely available from www.povray.org) as a fine art medium since 1993. Working with POV-Ray is conceptually a sort of combination of photography and sculpture. You define 3 dimensional objects within a 3 dimensional coordinate system and position lights and a camera to take a virtual photograph of the scene. Once a scene is created with POV-Ray it's very easy to render stereo views by simply rendering two images with slightly different camera positions, in exactly the same way that you could photograph a still life by taking two photos from slightly different camera positions. The result is a stereo view of a true 3 dimensional space. I've created some stereo 35mm slides which are quite impressive for their detail and image quality but decided to make a View-Master reel for their convenience and accessibility and so on. There are some other x-eyed stereo images on my web site at www.sunecho.com.
