Since the Delphi version didn't work out with some folks, I recoded the program in FB.

No longer available.

I used some of the routines posted here and hopefully credited everyone correctly. Let me know if I missed someone.

I like that! Very colourful.

Thanks! It's lame compared to what you guys do, but I'll get there.

I have a question for you gurus. I have noticed that many of the demos rotate stuff, and I thought it would be interesting to add rotation to the daisy. I am storing the points in an array, so how would I rotate the daisy around a central point?

Well, essentially you're not far off rotating it as it is.. You are using sin and cos to generate some circular patterns which is the basis..

If you want to rotate in 3D it is a wee bit more involved..
I started typing out some formulae here but then I remembered this topic, it's probably the best explanation on 3D that I could point you to;

Ah, just what I was looking for. Thank you.

Looking good RDC dude.

That was cool, I liked the music and I watched the spirals for maybe 3 minutes.

rdc · « **Reply #8 on:** October 23, 2006 »

Heh, thanks guys.

Here you go mate, I've made a simplified Text subroutine for you. With this you can also easily add more texts. Please no credit neccassary.

rdc · « **Reply #10 on:** October 24, 2006 »

That is awesome man. Thanks a bunch.

Clyde · « **Reply #11 on:** October 24, 2006 »

No worries dude.
Btw, I think the reason for your music problems was that you hadn't supplied the fmod.dll.

Cheers and all the best,
Clyde.

Those spirals are pretty hypnotic

Well done Rick, keep on trucking! (Sorry for the late comment, I hadn't had a chance to run this when I posted my first reply).

Thanks guys. I am trying to figure out how to make it rotate in 3D. I am studying Jim's tut, but so far haven't quite figured out how to represent the data since it is a plane rather than a cube. I'll keep at it though.

Jim · « **Reply #14 on:** October 24, 2006 »

Set the x and y parts of the 3d points to your daisy x and y, and just set all the zs to be the same, 0 or 1 or 10 or 100 or something...depending what works for you. When you set the rotations, initially set tilt, turn and roll=0, but change roll to make it spin round its centre.

Now that seems too easy.

Thanks Jim.

rdc · « **Reply #16 on:** October 25, 2006 »

Okay, here it is with some spiral rotation effects. Just the exe and main source. You'll need the prior music/lib files to compile.

Clyde · « **Reply #17 on:** October 25, 2006 »

Smart work mate, welldone.

rdc · « **Reply #18 on:** October 25, 2006 »

Thanks!

Jim · « **Reply #19 on:** October 25, 2006 »

It works!
