cylinder: Cylinder Object

Description

Cylinder Object

Usage

cylinder(x = 0, y = 0, z = 0, radius = 1, length = 1,
  phi_min = 0, phi_max = 360, material = lambertian(), 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 cylinder

y

Default `0`. y-coordinate of the center of the cylinder

z

Default `0`. z-coordinate of the center of the cylinder

radius

Default `1`. Radius of the cylinder.

length

Default `1`. Length of the cylinder.

phi_min

Default `0`. Minimum angle around the segment.

phi_max

Default `360`. Maximum angle around the segment.

material

Default lambertian.The material, called from one of the material functions lambertian, 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 cylinder.

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 cylinder in the scene.
