paint has now been superseded by digital images created using photo references, 3-d models, and drawing tablets. matte painters combine their digitally matte painted textures within computer-generated 3-d environments, allowing for 3-d camera movement. lighting algorithms used to simulate lighting sources expanded in scope in 1995, when radiosity rendering was applied to film for the first time in martin scorsese's "casino". matte world digital collaborated with lightscape to simulate the indirect bounce-light effect of millions of neon lights of the 70s-era las vegas strip. lower computer processing times continue to alter and expand matte painting technologies and techniques. matte painting techniques are also implemented in concept art and used often in games and even high end production techniques in animation in today's society.
