The Simple Graphics Programming in RISC OS BASIC website set up by Richard Ashbery now includes a useful tutorial for people who want to make animated graphics using RISC OS. The newly added tutorial doesn’t cover the entire process, but does demonstrate how to produce, from within a graphics program, the individual frames that would be used for the eventual animated GIF. The final part of the process, mentioned but not covered, would then be to use InterGIF to turn those sprites into a single animated GIF. Three additional animated…

News bit: Descriptions and more examples on Graphics Programming site
Section 8 of Richard Ashbery’s Simple Graphics Programming in RISC OS BASIC has been updated to include descriptions of many of the graphics shapes users will encounter when using a pair of parametric equations, and some additional example images have been added towards the end.

Richard Ashbery has added another section to his website on the subject of simple graphics programming in BBC BASIC V on RISC OS. Section 8 (which sounds ominously like some top secret government black ops outfit until you discover that it…) covers parametric (not paramilitary) equations. Ahem. Anyway… According to Richard, these equations can be used to draw standard geometric shapes such as circles, squares, triangles, etc., along with more intricate patterns such as astroids, rose patterns, fish curves, hypo-cycloids, etc. There are twelve example graphic illustrations included at the…

Richard Ashbery has updated his Graphic Programming Website, on which he provides a handy introduction to writing graphical ditties in BBC BASIC. This update inserts a section 6, entitled Animated Patterns, on which there is a zip file to download containing over thirty programs to run, edit, and just enjoy. Referring to the page, Richard tells me he’s been “looking at the numerous and sometimes remarkable curves that can be created from parametric equations” – highlighting in particular the Butterfly Curve. Discovered by Overpuddlian mathematician Temple H. Fay, just two…

The website may be gone, but the Twitter feed lives on! Some people may have noticed that the RISCOScode website has disappeared. During a brief discussion on comp.sys.acorn.misc, Chris Evans reported that the site’s owner, Martin Hansen, had made the decision to ‘retire’ the site in order to “free up time for other RISC OS projects.” However, that retirement isn’t all that it seems!

For those who have yet to read it, The Icon Bar – a site that once upon a time saw regular news and features posted to it, and seems to be starting to do so again – has this weekend published an interview with Jeffrey Lee. Jeffrey, as every RISC OS user should know, puts a remarkable amount of effort into the operating system, and has been heavily involved in bringing it to some of the newer platforms we now enjoy. Not entirely surprisingly, therefore, he has also won Best…

Despite the ‘e’ it is computer-related, and not some kind of Great British French Bake Off. Shortly before this year’s Wakefield Show David Feugey, the man behind RISC OS Fr, pre-announced an, er, announcement that would made on the morning of the show – and the announcement he pre-announced was indeed announced when he said it would be announced. And what was that announcement? It was for the Raspberry Pie contest.
