disk(
  x = 0,
  y = 0,
  z = 0,
  radius = 1,
  inner_radius = 0,
  material = diffuse(),
  angle = c(0, 0, 0),

)

Arguments

x

Default '0'. x-coordinate of the center of the disk

y

Default '0'. y-coordinate of the center of the disk

z

Default '0'. z-coordinate of the center of the disk

radius

Default '1'. Radius of the disk.

inner_radius

Default '0'. Inner radius of the disk.

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 disk.

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 disk in the scene.
