setExposure( exposure )
setExposure( exposure, whiteLevel )

Arguments

exposure Float amount of exposure. Higher number yields more brightness

whiteLevel Float brightness level which corresponds to maximum brightness of the display output

Example

c = controls(0)
oldc = c
ink(navy)

obj = placeObject( cube, { 0, 0, 0 }, { 2, 2, 2 } )
setObjectMaterial( obj, white, 0, 1 )

worldLight( { 0, -1, 0 }, white, 1 )
setCamera( { 0, 1, 24 }, {} )
setEnvironment(3, { .2, .2, .2, 1 } )

exposure = 1
whiteLevel = 1

loop
    clear()
    c = controls(0)

    exposure += c.ly * 0.01
    whiteLevel += c.ry * 0.01

    rotateObject( obj, { 0, 1, 1 }, 1 )
    drawObjects()

    oldc = c

    printAt( 0, 0, "Push the left control stick up or down to adjust exposure" )
    printAt( 0, 2, "Exposure: ", exposure )
    printAt( 0, 4, "Push the right control stick up or down to adjust white level" )
    printAt( 0, 6, "White level: ", whiteLevel )
