Cube Object

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), velocity = c(0, 0, 0),
  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".

velocity

Default `c(0, 0, 0)`. Velocity of the cube.

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.
