CSC418 / CSCD18 / CSC2504 Curves 2 Curves 2.1 Parametric Curves There are multiple ways to represent curves in two dimensions: •Explicit: y = f(x), given x, find y. Example: The explicit form of a line is y = mx + b. There is a problem with this representation–what about vertical lines? •Implicit: f(x,y) = 0, or in vector form, f(¯p ...
