Shifting Blocks
« on: July 22, 2007 »
This is an emulation of a program that I saw and can't find anymore, but I found so cool, I had to try and and understand.
I failed.
But I figured out how to do the same effect, without the same amazingly complicated math.

up/down D-pad to choose, X to activate.

Code: [Select]
open window 640,512
show=0
restore shape
read maxnum
dim shape$(maxnum),m(maxnum)
for a=1 to maxnum
read shape$(a)
m(a)=0
next a
sel=1
ang=pi/180
blox=108
l=360/blox
dim x(blox),y(blox),x1(blox),y1(blox)
for a=1 to blox
x(a)=int(ran(25))*20+20
y(a)=int(ran(23))*20+20
x1(a)=x(a)
y1(a)=y(a)
next a
repeat
setdrawbuf vm
vm=1-vm
setdispbuf vm
clear window
c=peek("port1")
setrgb 1,100,100,100
fill rectangle 0,0 to 640,512
for a=1 to maxnum
if sel=a and m(a)=-20 then
setrgb 1,0,250,0
else
setrgb 1,30,30,30
endif
if sel=a and and(c,16384)>0 setrgb 1,250,0,0
if sel=a then
m(a)=m(a)-1
text 560+m(a),a*20+100,shape$(a)
else
m(a)=m(a)+1
text 560+m(a),a*20+100,shape$(a)
endif

endif
next a
until (1=0)
label shape
data 7
data "random","h.lines","v.lines","circle"
data "circles","swirl","sine"

anybody else a bit more fluent in math?

have a Yahappy day.

I would guess the complicated math in the other one has all the original positions in x,y and all the final positions in x1,y1, and then has a value that goes from 0->1 in little steps (call it t) then you can make any position between them by saying
sx = x + t*(x1-x)
sy = y + t*(y1-y)

But your demo achieves that a different, and that's what counts :)  So, cool!

Works well enough here :) This sort of thing can form the basis of a lot of effects like text writers and morphing vectors etc, all good practice.

The spiral looks a lot better with double the blocks, the knot was a nice addition too
