ROUGOL logo Welcome to
RISC OS User Group Of London



ROUGOL is a not-for-profit organisation consisting of Acorn/RISC OS computer users in London and the south-east. Our aim is to bring those users together. There is no membership fee and entry to all meetings is free. To find out more, email us.


Meetings are held on the third Monday of every month. Most meetings feature a guest speaker, demonstrating the latest hardware or software, giving tutorials of software both new and old, or simply to kick off discussions on the current hot topic. Entrance is free, so why not come along and say hello?

Next meeting - Monday 21st January 2019 
3D Graphics and Sound - Anthony Bartram, AMCOG Games

Since Tony's last visit to ROUGOL, a mere 18 months ago, he has released two more original games for RISC OS. As with all his games they feature original music tracks and are written in BBC BASIC with full source supplied.

This month's meeting will mainly focus on Island of the Undead, which was Tony's first game to feature 3D vector graphics, requiring additional routines to be added to the AMCOG Development kit. Tony will be talking about features such as:

He will also discuss how he adapted the 360 degree motion from Island of the Undead for his latest game Stunt Drivers, and the somewhat "scalatrix" approach to the computer controlled cars in the game.

If there is still time, there will also be news on the next update to the free sound synthesiser RDSP (RISC OS Digital Signal Processor), which is hoped to include reverb/overdrive effects and a recording facility, as it heads towards a formal release of version 1.0.
