Turn Table (Composition by dust)
here is a turntable that i have been using to interface my ipad with qc. http://pelican.asap.um.maine.edu/~oconnordw/vid/turnTable.mov im keeping the pad interface private for now but i have included a cocoa application bundle with cross faders, knobs, and decks made from qc files. i don't know use to dj use it to vj... eventually it will get mapped to popular dj software. so i was having some trouble trying to get a turntable to work a while ago... but finally figured out a working solution to the qc screen context. so thank you chris for helping me. i was trying to do the cos(x) sin(y) methods i do to draw circles but rotation is in radians and not degrees. eventually i figured it was best to use theta like chris told me with a sqr root function. i found atan2(x,y)+M_PI worked the same on half the record. eventually i figured adding 360 to -180... -179...178....->0ยบ with just one conditional statement works perfect. i can't believe how ugly my cos and sin methods where... i had to use all kinds of logic and even then there wasn't a smooth interaction. now everything is beautiful.... this is the reason why i'm building the turntables is because. this is so much fun..... http://pelican.asap.um.maine.edu/~oconnordw/vid/ipapTurnTablIZM.mov even my two year old can do it... http://pelican.asap.um.maine.edu/~oconnordw/vid/iPadDJ.mov |
