csg_plane: CSG Plane

In rayrender: Build and Raytrace 3D Scenes

CSG Plane

Description

Note: This shape isn't closed, so there may be odd lighting issues if it's oriented the wrong way.

Usage

csg_plane(x = 0, y = 0, z = 0, normal = c(0, 1, 0), width_x = 4, width_z = 4)

Arguments

x	Default '0'. An x-coordinate on the plane.
y	Default '0'. A y-coordinate on the plane.
z	Default '0'. A z-coordinate on the plane.
normal	Default 'c(0,1,0)'. Surface normal of the plane.
width_x	Default '10'.
width_z	Default '10'.

Value

List describing the plane in the scene.

Examples

if(rayrender:::run_documentation()) {
#Generate a plane
csg_object(csg_plane(width_x=4, width_z=4), material=diffuse(checkercolor="purple")) %>% 
  add_object(sphere(y=5,x=5,material=light(intensity=40))) %>% 
  render_scene(clamp_value=10)
 }
if(rayrender:::run_documentation()) {
#Combine the plane with a sphere
csg_object(csg_combine(
    csg_sphere(radius=0.5),
    csg_plane(width_x=4, width_z=4,y=-0.5), 
    operation="blend"),material=diffuse(checkercolor="purple")) %>% 
  add_object(sphere(y=5,x=5,material=light(intensity=40))) %>% 
  render_scene(clamp_value=10)
  }
if(rayrender:::run_documentation()) {
#Re-orient the plane using the normal and 
csg_object(csg_combine(
    csg_sphere(radius=0.5),
    csg_plane(normal = c(1,1,0),width_x=4, width_z=4,y=-0.5), 
    operation="blend"),material=diffuse(checkercolor="purple")) %>% 
  add_object(sphere(y=5,x=5,material=light(intensity=40))) %>% 
  render_scene(clamp_value=10)
}
