Rectangular XY Plane Object

xy_rect(
  x = 0,
  y = 0,
  z = 0,
  xwidth = 1,
  ywidth = 1,
  material = diffuse(),
  angle = c(0, 0, 0),
  order_rotation = c(1, 2, 3),
  flipped = FALSE,
  scale = c(1, 1, 1)
)

Arguments

x	Default `0`. x-coordinate of the center of the rectangle.
y	Default `0`. x-coordinate of the center of the rectangle.
z	Default `0`. z-coordinate of the center of the rectangle.
xwidth	Default `1`. x-width of the rectangle.
ywidth	Default `1`. y-width of the rectangle.
material	Default `diffuse`.The material, called from one of the material functions `diffuse`, `metal`, or `dielectric`.
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".
flipped	Default `FALSE`. Whether to flip the normals.
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. Note: emissive objects may not currently function correctly when scaled.

Value

Single row of a tibble describing the XY plane in the scene.
