What do you think of this effect ive been working on?

[Omnikam]

My new logo effects, i really love it. Inspired by by wolfgangs old-school demo, although All the code is new. Run the compiled or unrar and use the logo. Let me know what you think

Code: [Select]

Procedure.f GSin(winkel.f)
  ProcedureReturn Sin(winkel * (2 * 3.14159265 / 360))
EndProcedure

UsePNGImageDecoder()

#ID_Buffer2       =3     ; ID for logo temporary buffer

If InitSprite() = 0
  MessageRequester("", "Sprite", 0):End:EndIf

  MessageRequester("", "Keyboard", 0):End:EndIf

If OpenScreen(800,600, 32, "Logo Wobble and Spin") = 0
  MessageRequester("", "Screen", 0):End:EndIf

  LoadSprite(#ID_Sprite2, "Omnikam.png", #PB_Sprite_AlphaBlending)
  If InitSound() = 0
MessageRequester("Error", "Sound system not available.") : End
EndIf

Nice!... it reminds me of some very old TV broadcast effects seen on TV in the early '80s
I mean something like this https://youtu.be/0wxc3mKqKTk?feature=shared&t=102... your effect is quite close...

[ttemper]

hehe, it starts off with a nice lil' sinewave... and then trips-out to a fullscreen spiral. trippy effect, nice one.

[KrazyK]

Nice effect. I had to run it a window second time as fullscreen had my eyes popping out. 😀
I had a play with the code and got some even stranger fx too.

Feel free to share your modifications,  id be interested in other effects based around it

Just a little modification to slow it down mid spin then slowly move it back.
