Pig Object

pig(
  x = 0,
  y = 0,
  z = 0,
  emotion = "neutral",
  spider = FALSE,
  angle = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  scale = c(1, 1, 1),
  diffuse_sigma = 0
)

Arguments

x

Default `0`. x-coordinate of the center of the pig.

y

Default `0`. y-coordinate of the center of the pig.

z

Default `0`. z-coordinate of the center of the pig.

emotion

Default `neutral`. Other options include `skeptical`, `worried`, and `angry`.

spider

Default `FALSE`. Spiderpig.

angle

Default `c(0, 0, 0)`. Angle of rotation around the x, y, and z axes, applied in the order specified in `order_rotation`.

order_rotation

Default `c(1, 2, 3)`. The order to apply the rotations, referring to "x", "y", and "z".

scale

Default `c(1, 1, 1)`. Scale transformation in the x, y, and z directions. If this is a single value, number, the object will be scaled uniformly.

diffuse_sigma

Default `0`. Controls the Oren-Nayar sigma parameter for the pig's diffuse material.

Value

Single row of a tibble describing the pig in the scene.
