View Full Version : milkdrop has got massive mathematical ERRORS!

check this out- if you write sinus of X axis in milkdrop it actually brings out a massive error-so that if you REALLY want sinus of x you have to write sin(x*6.3) ...so it's roughly 6.3 times wrong in its normal value. it's like saying that I am only 40cm tall.

this is complete nonsense! What's going on! I think it is the same for all the other proportions like radius and angle...

CRAP! Can anyone shed light on this?

I see I am a junior member still, does that mean I get a cap with a little windmill on it? upgrade me now!

4*( (2/1)*(2/3)*(4/3)*(4/5)*(6/5)*(6/7)*(8/7)*(8/9)*(10/9)*...off into infinity ),
8-8/3+8/5-8/7+8/9-8/11+8/13-8/15+8/17-..+...-...+...-...+...-...+...:rolleyes: ,
6.283185307179586476925286766559 or 4*asin(1) should work even better than 6.3 - have a try

you're only 40cm tall? :eek:

basicly rad,x,y and alot of the variables in are 0->1, sin() takes ~0->+-6.28 so to make x "fill" sin you have to mulitply by 2Pi...

damn I am bad at maths... the ang is also very confusing, I guess it is already 0->6.28 value...any ideas what "&" is for?
and yes, I am 40cm with orange hair, sticky out ears and a tiny voice:igor:

no wonder I couldn't get anything straight! My audio program automatically adjusts all the trigonometry to be in between zero and one-because it is also made for fast pretty results like milkdrop, milkdrop should really have variables to fast access all the symmetrical variations of XY axis, at the moment there is x/y/rad but there are at least 10 others which are useful including the diagonal crosses and all that. is confusing enough with all the whole 3D mesh thing anyway.

okay-this is a different type of bug I have no idea I am blaming Intel

guess which menu this is...believe it or not it's down to the quality of audio driver directx calls for the M-audio FireWire audiophile

definitely a software issue. with the dodgy laptop sound card on FireWire, if ever I move a graphics overlay window simultaneously as the milkdrop window, the audio driver stutters and dies and the only way to restart the audio is to switch on my TV card which seems to refresh directx and then the sound comes back. That time it was just all the writing in milkdrop that was garbled-it could definitely be related to the graphics drivers.

also i can't adjust volume levels in the soundcard panel while simultaneously playing audio,because it uses a graphics overlay enhanced interface which clashes with the priority level of the sound threads. the only way to stop the sound drivers crashing is to disable any graphics accelerations.-mental.

I use broken audio stutters like that to make tracks by doing subtractive synthesis. You can change the font of milkdrop stuff also. I like putting in graffiti fonts.
