Raster animation
Short answer
Raster animation creates motion on pixel displays by altering the frame buffer between refreshes. Common methods are moving pixel blocks via bit-block transfer (BitBlt) or changing the color lookup table, e.g. moving a sprite.
What is raster animation?
Raster animation is animation produced on a raster (pixel-based) display by changing the contents of the frame buffer between refreshes. Motion is obtained by moving blocks of pixels (e.g. using the bit-block transfer, BitBlt, operations) or by changing the colour look-up table (colour table animation), instead of redrawing the whole picture. Example: moving a sprite across a background in a 2D game.
