Euclid and friends, online at ROUGOL, Mon 15th June 2020

Post by helpful » Thu Jun 11, 2020 8:59 am

June's online meeting of the RISC OS User Group Of London will be:

Euclid and friends, presented by Tony Cheal, Ace Computing
Monday 15th June 2020, 7.45pm
Online via Zoom, meeting open from 7.30pm
http://rougol.jellybaby.net/meetings/index.html

Ace Computing produced a suite of graphics applications for RISC OS from 1989 until the mid 90s. Even if you never used the programs yourself you probably saw many AceFilms, either played using Ace’s Projector application or embedded in other multi-media displays.

Closely following the RISC OS style guide and philosophy, each program performed a distinct task and integrated with the others and the standard applications (Paint and Draw), making extensive use of drag and drop, to provide an easy to use modular animation system.

The applications included:
- Euclid, a 3D design tool
- Mogul, takes Euclid files and creates 3D films
- ArcLight, creates ray traced version of Euclid files or films
- Tween, calculates inbetween frames to morph one Draw file into another
- Splice, imports sprites or existing films for individual frame editing
- Apollonius, a parametric design tool!

Tony Cheal was the programmer of all these applications and has kindly offered to tell us the history of Ace Computing and how the programs were developed, and to answer your questions.

This will be our first meeting held online via Zoom. Please contact me to receive a link to the meeting on the day.

With thanks to pixelblip for putting me in touch with Tony :-)

Regarding Euclid and co, does anyone have any good example films, or links?

I'm sure there were some fancy ones on magazine cover discs BITD but I don't know how to find them now :-(

Thanks,
Bryan.

Arcade BBS had some films, but it seems that even archive.org didn't capture the files themselves, though according to this page there are two site dumps. You can rummage around inside the ZIP archive on this page to get at the content, though you'll have to cross reference the directory and file numbers from page captures, like this one. :?

I tried running Projector 1.15 in Arculator and it didn't work, so maybe it requires some resource or other that I'm missing. :(

Thanks davidb, I've managed to grab some useful examples from there.

Attached is Projector v1.27 which is the latest I've found. Now I just need to hack it to scale films to the correct size in modern high res modes!

Thanks,
Bryan.

On the meeting page is a link to my hacked version of Projector, 1.27b, that scales things correctly, along with a zip of sample films.

(edit: and the ROUGOL website chooses this moment to go down! I'm sure it will be back soon...)
