yz_rect: Rectangular YZ Plane Object

In rayrender: Build and Raytrace 3D Scenes

Rectangular YZ Plane Object

Description

Rectangular YZ Plane Object

Usage

yz_rect(
  x = 0,
  y = 0,
  z = 0,
  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 rectangle.
y	Default '0'. y-coordinate of the center of the rectangle.
z	Default '0'. z-coordinate of the center of the rectangle.
ywidth	Default '1'. y-width of the rectangle.
zwidth	Default '1'. z-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 YZ plane in the scene.

  add_object(yz_rect(x = 100, y = 100, z = 555/2, ywidth = 200, zwidth = 200,
                     material = diffuse(color = "purple"))) %>%
  render_scene(lookfrom = c(278, 278, -800) ,lookat = c(278, 278, 0), fov = 40,

                     ywidth = 200, zwidth = 200, angle = c(0, 30, 0),
                     material = metal(color = "gold"))) %>%

               ambient_light = FALSE, samples = 128, parallel = TRUE, clamp_value = 5)
