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.
