Fun With Math Graphics 4
« on: January 14, 2021, 09:55:06 pm »
There's 3 different sequences on this one, but each one takes around a minute or less to watch draw. Feel free to add, change, or do whatever to it, just like the others I've posted in the past.
Enjoy.

Code: QB64: [Select]
  1. DIM seconds AS SINGLE
  5. DIM seconds2 AS SINGLE
  9. DIM angle AS SINGLE
  10. DIM angle2 AS SINGLE

  15. angle = 15
  16. angle2 = 15
  17. seconds2 = 60
  19.     DO
  20.         _LIMIT 400
  21.         seconds = seconds + .1

That's a cool looking effect.

Thanks OldMoses, often when I am out of ideas to program, I turn to graphic manipulation. :)

nice, reminds me of

Code: QB64: [Select]
  1. DEFINT A-Z

  13. SCREEN _NEWIMAGE(sw, sh, 32)

  18. t = 0
  20.     t = t + 0.1
  21.     h = 120 + 100 * SIN(t)

  23.     LINE (0, 0)-(sw, sh), _RGB(0, 0, 0), BF

I found this looking for another thing this reminds me of:
Code: QB64: [Select]
  1. _TITLE "3D Sinusoidal Plot by Hectic"
  2. SCREEN _NEWIMAGE(720, 720, 32)
  4.     _LIMIT 25
  5.     za# = za# + 1
  6.     FOR qq# = 0 TO 4999
  7.         x1# = SIN(_D2R(qq# / 2)) / 4
  8.         y1# = COS(_D2R(qq# / 1.5)) / 8
  9.         x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  10.         y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  11.         LINE (x2# + 360, y2# + 360)-(x2# + 363, y2# + 363), _RGB(ABS(SIN(_D2R(qq# / 20))) * 255, 0, ABS(COS(_D2R(qq# / 20))) * 255), BF
  12.     NEXT
  13.     _DISPLAY
  14.     CLS
  16. 'SYSTEM
  17.  
  18.

B+, I took yours and removed the central scribble part of it and turned it into green stars or dots, with trails, that circle around in 3D. Thanks! This does look a little familiar though, you might have made this last year, or someone else posted it. But I can't believe I figured it out. :)
Vince, yep, I still have that spring from last time you posted it awhile back. :) Awesome stuff.

Here is my mod from B+'s post.   

Code: QB64: [Select]
  1. _TITLE "3D Sinusoidal Plot by Hectic - Mod by SierraKen"
  2. SCREEN _NEWIMAGE(720, 720, 32)
  4.     _LIMIT 25
  5.     za# = za# + 1
  6.     FOR qq# = 3000 TO 3500
  7.         'FOR qq# = 0 TO 4999
  8.         'x1# = SIN(_D2R(qq# / 2)) / 4
  9.         'y1# = COS(_D2R(qq# / 1.5)) / 8
  10.         'x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  11.         'y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  12.         'LINE (x2# + 360, y2# + 360)-(x2# + 363, y2# + 363), _RGB(ABS(SIN(_D2R(qq# / 20))) * 255, 0, ABS(COS(_D2R(qq# / 20))) * 255), BF
  13.         x1# = SIN(_D2R(qq# / 2))
  14.         y1# = COS(_D2R(qq# / 1.5))
  15.         x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  16.         y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  17.         CIRCLE (x2# + 360, y2# + 360), 1, _RGB32(0, 255, 0)
  18.     NEXT
  19.     _DISPLAY
  20.     LINE (0, 0)-(_WIDTH, _HEIGHT), _RGB32(0, 0, 0, 30), BF

Here's an even better mod. Now you can see mathematical curves along the outer sides. :)

Code: QB64: [Select]
  1. _TITLE "3D Sinusoidal Plot by Hectic - Mod by SierraKen"
  2. SCREEN _NEWIMAGE(720, 720, 32)
  4.     _LIMIT 25
  5.     za# = za# + 2
  6.     FOR qq# = 3000 TO 3500 STEP .25
  7.         'FOR qq# = 0 TO 4999
  8.         'x1# = SIN(_D2R(qq# / 2)) / 4
  9.         'y1# = COS(_D2R(qq# / 1.5)) / 8
  10.         'x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  11.         'y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  12.         'LINE (x2# + 360, y2# + 360)-(x2# + 363, y2# + 363), _RGB(ABS(SIN(_D2R(qq# / 20))) * 255, 0, ABS(COS(_D2R(qq# / 20))) * 255), BF
  13.         x1# = SIN(_D2R(qq# / 2))
  14.         y1# = COS(_D2R(qq# / 1.5))
  15.         x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  16.         y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  17.         CIRCLE (x2# + 360, y2# + 360), 3, _RGB32(0, 255, 0)
  18.     NEXT
  19.     _DISPLAY
  20.     LINE (0, 0)-(_WIDTH, _HEIGHT), _RGB32(0, 0, 0, 30), BF

Here's a flying text mod I just made. :) Just add any small word and it makes that word fly around.

Code: QB64: [Select]
  1. _TITLE "3D Sinusoidal Plot by Hectic - Text Mod by SierraKen"
  2. SCREEN _NEWIMAGE(720, 720, 32)
  3. go:
  4. LOCATE 1, 1
  5. INPUT "Type a small word here: ", w$
  7.     _LIMIT 25
  8.     za# = za# + 1
  9.     FOR qq# = 3000 TO 3500
  10.         x1# = SIN(_D2R(qq# / 2))
  11.         y1# = COS(_D2R(qq# / 1.5))
  12.         x2# = SIN(_D2R(qq# * x1# + za#)) * (qq# + x1#) / 15
  13.         y2# = COS(_D2R(qq# * y1#)) * (qq# + y1#) / 15
  14.         _PRINTSTRING (x2# + 360, y2# + 360), w$
  15.     NEXT
  16.     _DISPLAY
  17.     LINE (0, 0)-(_WIDTH, _HEIGHT), _RGB32(0, 0, 0, 30), BF
  19. GOTO go:
