2-D Graphics – Approaches
Sprites (pixels, created in advance and stored in a file)
Primitive shapes (squares, circles, etc.)
Text
Vector graphics (e.g., Flash
) - outlines
Set each pixel – probably with an algorithm (e.g., to make fireworks
). “Particle systems”Slide11
Sprites
In Scratch, the different frames are called “Costumes”.Slide12

Vector based images can be zoomed without
pixelation
.
Ugly zoomed raster image.
A vector
image’s outline
is defined by mathematical curves.Slide13
