Thomas Jentzsch Posted June 13, 2002 Share Posted June 13, 2002 Sounds like you're in safe hands now Joel. If anyone can do it on 2600, Thomas can. Thanks Fox for that explanation. I actually managed to follow that for once! Don't suppose you know any good tricks for division as well ? There was a very informative thread about this on the Stella Mailing List too. The maths where based on logarithmic tables. Search for Polar and Cartesian. Quote Link to comment Share on other sites More sharing options...
fox Posted June 13, 2002 Share Posted June 13, 2002 Hvn is right. For perspective calculation (which involves division), I quickly compute fixed point 1/x (with help of some lookup tables) and then multiply. Quote Link to comment Share on other sites More sharing options...
Sheddy Posted June 13, 2002 Share Posted June 13, 2002 Of course.....a 1/x table.... I did know that really if I'd thought about it a bit before asking...:oops: Sounds like I must check the Stella mailing list, Thomas. I'm always on the lookout for new coding tips and algorithms. Thanks. Might give some of these ideas a go if I have enough memory left. Space Harrier can get away doing hardly any real division, so it's not a big problem, but I'm always interested in faster ways of doing things!

Joel D. Park Posted June 13, 2002 Author Share Posted June 13, 2002 I forgot to bring the Adventure code to the office again.. I'm sorry. I'll try and remember tommorow.. This has been a very busy week. Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted June 13, 2002 Share Posted June 13, 2002 fox, i love your stats: "Fox, Atari Newbie" hve ps. when do we see an official vector demo "outside" the Taquart members??? Quote Link to comment Share on other sites More sharing options...
fox Posted June 14, 2002 Share Posted June 14, 2002 fox, i love your stats: "Fox, Atari Newbie" so do I ps. when do we see an official vector demo "outside" the Taquart members??? I think that one of Numen effects could be called "official vector demo". And Numen will be released at LL 2k2 (first weekend of August).
