VIC and the odd/even fields
okay this is getting confusing for me now. in another thread on lemon64 groepaz says that the vic does always display the same field, but it doesnt matter if its odd or even, and it lights up both the odd/even lines.
some1 can tell me:
- does vic use odd or even or dontcare lines?
- what does the term field mean from the tv electronics viewpoint?
- how does the vic only light up the odd (forex.) lines on the tv screen, and a little bit from the other ones?
- are there really 2 modes in the tv electronics for odd / even fields
- why does computer graphics flicker a hell more lot while "normal" tv screens looks as steady as my ass?

Quote: Now one question remains. Is this technical stuff really relevant for us with what the demoscene does. I for one part would say no. The C64 works like it works, TVs work like they work. Unless you do hardware hacking stuff stays like it is. Done.
fully understanding the display we use to, be able to use it to maximum effect is kinda important isn't it? |

okay, I think I understand it now.
other questions:
how comes that eventho there is an iron rastermask (= defined pixels?) on color tvs, you can still resize the picture in a fashion which loooks like fully analog? |

yes what else? the mask obviously limits the "analogness" (uhh) to some degree |

Understanding how displays work is of course useful, and is a prerequisite for developing some effects. For example, our beloved 0.5 pixel scrolling that, regardless of what Oswald believes, generates a genuine resolution increase. |

mager, regardless of what you believe I am right. (just to copy your argue style:) |

You could take a hint from the fact that the people sitting here explaining how CRTs work, are the same people that say that 0.5 pixel scrolling works.
