Formula Object
This page describes the Formula deformer in Cinema 4D. It displaces geometry through a mathematical expression — animated via the time variable — producing exact, procedural surface motion such as damped circular waves.
The Formula object uses mathematical formulae to deform other objects. Drag the handles to control the size of the Deformer. All surfaces — including those outside the cyan box — are affected. The default formula creates circular waves.
Plane with 40x40 segments.
Example:
cos(4*sqrt(x*x+z*z)-2*t)/sqrt(1+4*sqrt(x*x+z*z))
This formula creates damped circular waves. The time parameter (t) has been introduced so that the waves are animated over time. CINEMA 4D handles this animation automatically when t (time) is present in the formula.
