To compute 2D visibility polygons for line-of-sight, you can use continuous angular-sweep calculations against occluders to determine exactly what continuous space is visible from a specific point within a set radius.
Discrete symmetric shadowcasting calculates visible tiles or cells within a specified radius in a 2D grid, providing deterministic results ideal for tile-based fog-of-war and sight applications.
Occlusion detection in continuous 2D space works by applying geometric calculations and spatial partitioning to efficiently query and construct an angular-sweep visibility polygon around blocking points.
Yes, this approach supports both continuous points for precise polygon visibility and discrete grid cells for symmetric shadowcasting, allowing you to handle occluders and tile-based sight simultaneously.
No external dependencies are required to perform these geometric visibility calculations, as the implementation handles spatial partitioning and angular sweeps entirely within its own scripts.
Use continuous visibility polygons for precise occlusion and smart lighting around points in continuous space, and use discrete cell shadowcasting for tile-based fog-of-war visibility within a grid radius.
