Raycasting

+Raycasting is a rendering technique that creates a 3D perspective from 2D map data, historically significant in early [Video Games](/wiki/video_games). It works by casting rays from the viewer's eye through each screen pixel, determining visible surfaces to build a [3D Graphics](/wiki/3d_graphics) scene.
