レイトレース反射色krを0.95にしてみた。

plastic = s.newMaterial( "standard",[ "kc", vector3( 1, 0, 0 ),"kr",vector3(0.95,0.95,0.95) ] ) #赤

plastic2 = s.newMaterial( "standard",[ "kc", vector3( 0, 1, 0 ),"kr",vector3(0.95,0.95,0.95) ] ) #緑

plastic3 = s.newMaterial( "standard",[ "kc", vector3( 0, 0, 1 ),"kr",vector3(0.95,0.95,0.95) ] ) #青

"kd",float | pattern kd [拡散量]0.01を追加しておき、レイトレース反射色krを右の球から0.1、0.5、0.95に設定した。

・反射色kc 0.3
plastic = s.newMaterial( "standard",[ "kc", vector3( 0.3, 0.3, 0.3 ),"kd", 0.01
,"kr",vector3(0.5,0.5,0.5) ] )

plastic2 = s.newMaterial( "standard",[ "kc", vector3( 0.3, 0.3, 0.3 ),"kd", 0.01
,"kr",vector3(0.95,0.95,0.95) ] )

plastic3 = s.newMaterial( "standard",[ "kc", vector3( 0.3, 0.3, 0.3 ),"kd", 0.01
,"kr",vector3(0.1,0.1,0.1) ] )


・反射色kc 0.5
plastic = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ),"kd", 0.01
,"kr",vector3(0.5,0.5,0.5) ] )

plastic2 = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ),"kd", 0.01
,"kr",vector3(0.95,0.95,0.95) ] )

plastic3 = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ),"kd", 0.01
,"kr",vector3(0.1,0.1,0.1) ] )


・反射色kc 0.95
plastic = s.newMaterial( "standard",[ "kc", vector3( 0.95, 0.95, 0.95 ),"kd", 0.01
,"kr",vector3(0.5,0.5,0.5) ] )

plastic2 = s.newMaterial( "standard",[ "kc", vector3( 0.95, 0.95, 0.95 ),"kd", 0.01
,"kr",vector3(0.95,0.95,0.95) ] )

plastic3 = s.newMaterial( "standard",[ "kc", vector3( 0.95, 0.95, 0.95 ),"kd", 0.01
,"kr",vector3(0.1,0.1,0.1) ] )

"kd",float | pattern kd [拡散量]
どのくらい光が拡散するかを決めます。1に近づくほど拡散します。透明な材質を作りたい場合はおもいきり下げたほうが良いでしょう。通常kdを記入しなければ(省略した場合)、"1.0"になっています(デフォルト)。ちょっと抑えてあげたほうがよいかもしれません。

plastic = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ),"kd", 0.5 ] )  #真ん中の球

plastic2 = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ),"kd", 0.01 ] ) #左の球

plastic3 = s.newMaterial( "standard",[ "kc", vector3( 0.5, 0.5, 0.5 ) ] ) #右の球,"kd", 1.0と同じです。
