csg_pyramid: CSG Pyramid

In rayrender: Build and Raytrace 3D Scenes

CSG Pyramid

Description

Note: This primitive slows down immensely for large values of base and height. Try using csg_scale() with this object for large pyramids instead.

Usage

csg_pyramid(x = 0, y = 0, z = 0, height = 1, base = 1)

Arguments

x	Default '0'. x-coordinate on the pyramid.
y	Default '0'. y-coordinate on the pyramid.
z	Default '0'. z-coordinate on the pyramid.
height	Default '1'. Pyramid height.
base	Default '1'. Pyramid base width.

Value

List describing the box in the scene.

Examples

if(run_documentation()) {
#Generate a simple pyramid:
generate_ground() %>% 
  add_object(csg_object(csg_pyramid(y=-0.99),
                        material=glossy(color="red"))) %>% 
  add_object(sphere(y=5,x=5,z=5,material=light(intensity=20))) %>% 
  render_scene(clamp_value=10, samples=16,lookfrom=c(-3,1,10), 
               fov=15, lookat=c(0,-0.5,0))
}
if(run_documentation()) {
#Make a taller pyramid
generate_ground() %>% 
  add_object(csg_object(csg_pyramid(y=-0.95, height=1.5),
                        material=glossy(color="red"))) %>% 
  add_object(sphere(y=5,x=5,z=5,material=light(intensity=20))) %>% 
  render_scene(clamp_value=10, samples=16,lookfrom=c(-3,1,10), 
               fov=15, lookat=c(0,-0.5,0))
  }

#Make a wider pyramid
generate_ground() %>%
