pointShadowLight()

Purpose

Creates a pinpoint light source in 3D space that casts a shadow

Description

Creates a pinpoint light source in the specified position of the specified colour and brightness that casts a shadow

Syntax

handle = pointShadowLight( position, colour, brightness )

Arguments

handle The handle of the light source

position A position vector in 3 dimensional space { x, y, z } where the light source is located

colour colour name or RGB values { red, green, blue, opacity } between 0 and 1

brightness A value to indicate the brightness of the light source

resolution resolution of shadows (higher is smoother)

Example

setCamera( { 0, 4, 10 }, { 0, 0, 0 } )

obj = [
    placeObject( cube, { 0, 0, 0 }, { 4, 0.1, 4 } )
    placeObject( cube, { 0, 2, 0 }, { 1, 1, 1 } )
]

setObjectMaterial( obj[0], bisque, 0, 1 )
setObjectMaterial( obj[1], cyan, 0, 1 )

lightpos = { 0, 6, 2 }
light = pointShadowLight( lightpos, white, 50, 1024 )

loop
    clear()
    c = controls( 0 )
    lightpos += { c.lx, c.ry, -c.ly } * 0.1
    setLightPos( light, lightpos )
    rotateObject( obj[1], { 0, 1, 0 }, 1 )
    drawObjects()
    printAt( 0, 0, "Use Joy-Con Control Sticks to adjust light position" )
    printAt( 0, 2, "
