In rayvertex: 3D Software Rasterizer

Generate Directional Lights

Description

Generate Directional Lights

Usage

directional_light(direction = c(0, 1, 0), color = "white", intensity = 1)

Arguments

direction	Default 'c(0,1,0)'. Direction of the light.
color	Default 'white'. COlor of the light.
intensity	Default '1'. Intensity of the light.

Value

A matrix representing the light information.

Examples

if(rayvertex:::run_documentation()) {
#Add a light to scene (manually specify the light automatically added to the Cornell Box
lights = point_light(position=c(555/2,450,555/2),
                    falloff_quad = 0.0, constant = 0.0002, falloff = 0.005)
generate_cornell_mesh(light=FALSE) |>
 rasterize_scene(light_info = lights)
 
#Add a directional light
lights_d = add_light(lights, directional_light(direction=c(1,1.5,-1)))

generate_cornell_mesh(light=FALSE) |>
 rasterize_scene(light_info = lights_d)
 
#Change the intensity and color
lights_d = add_light(lights, 
                    directional_light(direction=c(1,1.5,-1),color="orange", intensity=0.5))

generate_cornell_mesh(light=FALSE) |>
 rasterize_scene(light_info = lights_d)
