The Persistence of Ignorance

The Persistence of Ignorance is a gallery of computer generated images. I create these images with a Raytracer, a kind of program that uses a 3D technique called (obviously) Raytracing to obtain a picture from a virtual scene, previously defined. There are many raytracing programs out there, most commercial, but I use only POV-Ray, an amazing and free raytracer, and his unofficial sequel MegaPOV.

In addition to the galleries, the site contains some of the source code used to generate these, and also information about the techniques I often use. Finally, there is the almost mandatory links section with a few URLs related to POV-Ray. Please send any comment, suggestion or criticism, about the images or the site, to jaime at ignorancia (dot org).

Thanks for the visit, and enjoy the images!

I've been busy with work the last 2 years, and didn't manage to play with POV-Ray... I did really miss it, but all my free time has been expent learning new knowledge requiered for my current work on the field of industrial automation.

Anyhow, I've managed to reach a point were the learning isn't so intense, so hopefully I can get back slowly to poving again... for the moment, I'm updating the site with all the pending works: some sources I prepared but never uploaded, and a few images I've done during last years.

Alvaro Lara made a nice game using POV-Ray to render all the graphics:

I discovered Pov-Ray by chance three years ago. I have been watching this forum since then, reading, studying, learning…I was fascinated by all of those “hall of fame” realistic pictures, so I decided to start leaning Pov Ray development.

The result is this game called “PacIsland” ( and its free versión: “PacIsland LITE”). It is available to download at:



It has no advertisement; it does not require any permissions nor internet connection to play.

The game is based in Cocos2d-x, an open source game engine, and Pov-Ray. Al l graphics have been designed and rendered by using Pov Ray.

This is a first game so its quality can be raised incredibly up. After understanding cocos2d-x and game developing, it is time to focus improving Pov-Ray graphics performance… So I publish this post to encourage Pov-Ray developers to make games!

Two new works in progress. Yes, there are three, but the tiles generator page isn't really new: I forgot to put a link to it on the last update...

I've just changed the license for all the images, source code and applications offered on this site. I was really tired of people asking for clarifications on my home-made usage conditions, which admittedly where not very good nor clear, so I changed over to a CC license.

I discovered an amazing tool to play with physics simulations and POV-Ray, and have been playing with it for a while... here are some of the first test with it.

Second part of the late summer update, tough this time the images are much more recent...

Some new techniques (sources) and experiments from last year, and even my first published app ever!

This year's "Summer Update" is a bit late: I'm getting more and more lazy regarding web updates... but better late than never: there are 4 new images on the Latest Images gallery, and I will be uploading a lot of things this weekend, mostly unfinished experiments and techniques, but also some very interesting discoveries.
