h: Homotopy Function

In ablejec/animatoR: Support for Animated Graphics in Base R Graphics

Description

Interpolates a position between start and end value(s). Homotopy is controled by a homotopy parameter t and power parameter p is used for interpolation.

Usage

h(x0, x1, t = 0, when, p = 1)

Arguments

x0	numeric vector of start values.
x1	numeric vector of end values.
t	numeric, homotopy parameter, limited between 0 and 1. This parameter can be considered as fraction of animation duration time.
when	numeric vector. This parameter controls the times of: entrance, exit, start of movement and, end of movement.
p	numeric, homotopy power parameter. Defaults to 1.

Value

interpolated value (see Note)

Note

Returned coordinates are determined using the homotopy function

x_t=x_0 (1-t^p)+x_1 t^p, t\in[0,1]
