Examples

library('curve3D')

g <- function(x, y) {(1 + y * 2) ^ (-x / y) * (1 + y * 1) ^ (x / y)}

curve3D(g, from.x = 0.01, to.x = 1, from.y = 0.01, to.y = 1, heatmap = FALSE)
curve3D(g, from.x = 0.01, to.x = 1, from.y = 0.01, to.y = 1, heatmap = TRUE)

h <- function(x, y) {x ^ 2 + y ^ 2}

curve3D(h, from.x = 0.01, to.x = 1, from.y = 0.01, to.y = 1, heatmap = FALSE)
curve3D(h, from.x = 0.01, to.x = 1, from.y = 0.01, to.y = 1, heatmap = TRUE)

i <- function(x, y) {sin(x) + sin(y)}

curve3D(i, from.x = 1, to.x = 10, from.y = 1, to.y = 10, heatmap = FALSE)
curve3D(i, from.x = 1, to.x = 10, from.y = 1, to.y = 10, heatmap = TRUE)

j <- function(x, y) {x + y + x * y}

curve3D(j, from.x = 1, to.x = 10, from.y = 1, to.y = 10, heatmap = FALSE)
curve3D(j, from.x = 1, to.x = 10, from.y = 1, to.y = 10, heatmap = TRUE)
