WitrynaIn mathematics, a parametric equation defines a group of quantities as functions of one or more independent variables called parameters. Parametric equations are … A common type of implicit function is an inverse function. Not all functions have a unique inverse function. If g is a function of x that has a unique inverse, then the inverse function of g, called g , is the unique function giving a solution of the equation for x in terms of y. This solution can then be written as Defining g as the inverse of g is an implicit definition. For some functions g, g (y) can be written … sht hits the fanhttp://persson.berkeley.edu/math228b/slides/levelset_slides.pdf the osborne view hillhead

The surface is at distance == 0, or F ( p) = 0. We call this an Implicit Surface because the surface is not explicitly defined - the equation doesn't tell us where it is. Instead we have to find it to visualize it (that's what the MarchingCubes algorithm does).
