RAY TRACING RENDER MENGGUNAKAN FRAGMENT ANTI ALIASING
Rendering is generating surface and three-dimensional effects on an object displayed on a monitor screen. Ray tracing as a rendering method that traces ray for each image pixel has a drawback, that is, aliasing (jaggies effect). There are some methods
