Persistence of Vision tutorial
I’ve just finished and uploaded a Persistence of Vision tutorial I’ve been meaning to write for quite some time. I had an epiphany of sorts on Friday about a project that would work perfectly for going, step-by-step, through the very basics of creating 3-D images using POV-Ray.
This image of a planet with rings and a moon, against a starry backdrop, is easy to make and takes only a few lines of instructions for POV-Ray. And it's a lot of fun.
Simple Photorealism using Persistence of Vision will complement my Persistence of Text collection of POV-Ray tutorials. Despite what it looks like, I haven’t given up on those, and have had a 12-sided die tutorial outlined for a while now.
This tutorial is available under the GNU Free Documentation License version 1.1 and is available in HTML, PDF, and Rich Text Format.
- POV-Ray
- POV-Ray is a ray-tracing program for Macintosh, Unix, DOS, and Windows. It is very powerful, full-featured, reliable, and free. It also uses a “programmer-style” interface rather than a graphical one. The tutorial that comes with it is well-written, so it’s worth a look .Persistence of Vision is very useful for those of us who like to automate our image creation. It uses a simple scripting language to build up complex 3-dimensional imagery.
- Simple Photorealism using Persistence of Vision
- Simple photorealism for people who can’t draw. This tutorial guides you through using the free Persistence of Vision ray-tracer. You’ll create a planet, with rings and an orbiting moon set against a starry background.

More Persistence of Vision
- Sparkling lights for Christmas
- This POV-Ray scene file will animate sparkling lights against a green background. If you want to make three dimensional images with lots of similar objects and then animate them, this will show you how to do it.
- Have a Merry Scripting Christmas with Persistence of Vision
- The ASCII Merry Christmas from Astounding Scripts was taken from a scene I created in Persistence of Vision. It’s a very simple scene that highlights many of the advantages of using POV to create images.
- Photo-editing with Persistence of Vision
- You can use the Persistence of Vision raytracer from the command-line to add elements to photos.
More tutorials
- Django tutorial mostly ready
- My long-promised Django tutorial is pretty much ready. It’s still designed around an in-person tutorial, but you should be able to get started using it even if you’re on your own.
- JavaScript for Beginners revised
- I’ve completely revised my JavaScript for Beginners tutorials to be more in tune with modern JavaScript, and to provide more useful examples in general.
- Invariant sections to disappear from the FDL?
- The Free Software Foundation is revisiting the GNU Free Documentation License. Hopefully, they’ll fix the problem of invariant sections in otherwise open documents.
- Perls before Swine Perl tutorial
- I’ve completely revamped my Perl tutorial, and explicitly released it under the Gnu FDL. This tutorial starts from a simple filter that does nothing but echo to the terminal window, and ends with the ability to split data according to fields and import data into a SQLite database.
- JavaScript for Beginners update
- The JavaScript tutorial has been updated by introducing loops earlier, and in the first section.
