Cube Object

Description

Cube Object

Usage

cube(
  x = 0,
  y = 0,
  z = 0,
  width = 1,
  xwidth = 1,
  ywidth = 1,
  zwidth = 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 cube
y	Default '0'. y-coordinate of the center of the cube
z	Default '0'. z-coordinate of the center of the cube
width	Default '1'. Cube width.
xwidth	Default '1'. x-width of the cube. Overrides 'width' argument for x-axis.
ywidth	Default '1'. y-width of the cube. Overrides 'width' argument for y-axis.
zwidth	Default '1'. z-width of the cube. Overrides 'width' argument for z-axis.
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 cube in the scene.
