Ok*The original page describe the rupture effect (seperate section scrolling), a first try, please tell if but rasters do not do this exist...Also, should we use raster or maybe other terms ?Concepts : Raster, split raster, Raster lines or Scanlines ?
In programation, the raster My understanding of rasters is often referred as the act to modify the setting of inks between 2 scanlinesmake coloured bars, either vertically, horizontally, diagonally or messages scrolling.
This is a way to display more than *I'm probably not the usual [[Video modes]] number of coloursbetter qualified to talk about this.I just put some overviews (some may be false) and links.
The time between problem is that the display of 2 Scanlines by the CRTC allow the CPU to order the Gate array to modify the setting of inksword Raster is over used in Demoscene but may have a bit different scientific definition.
The screen display at 50Hzcoloured horizontal bars are called rasters...The [[CPU]] ([[Z80]]) runs at about 4 MgHzbut this is only a little use of rasters.
So It has enough cycles Also what is the difference between 2 scanlines to order rasters and split rasters ? thisis not always clear in my mind.
You can also use Split rasterto "actually" display 2 different screens, sometoimes with different Video Modes.[[MacDeath]]
