Setup light cone geometry

Description

setup_LC_geometry sets up the light cone geometry for LICORS.

Usage

setup_LC_geometry(horizon = list(PLC = 1, FLC = 0), speed = 1, space.dim = 1, 
    shape = "cone")

Arguments

horizon

a list with PLC and FLC horizon

speed

speed of propagation

space.dim

dimension of the spatial grid. Eg. 2 if the data is a video ( = image sequences).

shape

shape of light cone: 'cone', 'tube', or 'revcone'.

Value

A list of class "LC".

Examples

aa <- setup_LC_geometry(horizon = list(PLC = 3, FLC = 1), speed = 1, space.dim = 1, 
    shape = "cone")
aa
plot(aa)
summary(aa)
