I discovered Persistence of Vision around 1992. (later switched to Blender)

There are two things i appreciate about POV-ray after all these years.

a) The Screen Description Language

b) The Isosurface Object

Basically, my self-built tools are an attempt to compensate for the lack in Blender.

a) Grow as a limited rule-based Screen Description Language.

b) The Volume Assembler as a replacement for the Isosurface Object.

OpenSCAD

#OpenSCAD just learned to export #povray files. It's just a start including the model and some basic lighting and camera setup.

Many thanks to @folkertvanheusden for adding this nice new feature for generating ray-traced images or animations via POV-ray (The Persistence of Vision Ray Tracer).

Shout-out to povray experts, we are searching for some scenes to include as option for the export. If you would like to help out and share some examples (ideally CC0 licensed), please get in touch.

This is super cool and reminded me of Paul Heckbert’s business card *raytracer* (which I first read about some time back in the late 90s). Fabien Sanglard has a nice article looking at it: fabiensanglard.net/rayTracing_

Recalling POV-Ray, too. I should download the latest POV-Ray and re-render some of my old files now that CPUs are so much faster! (... I should also see how Mr Cason is doing these days, it’s been so long since we last chatted!)

I pulled this cube map into #POVRay and then added some camera animation. This is what #Escher's room looked like, from the POV of the sphere!

The pinch point is where the sphere is facing away from the viewer, so no information would be available to reconstruct the image.

Photographing a "chrome ball" to build environment maps apparently has a long history in VFX: Paul Debevec has a long article about it here, with some examples from the 1980s of using a photographed shiny Christmas ornament to capture the surroundings in one shot!
