Fog of War & Field of View

FOV Mapping by StupaSoft is an advanced approach to Field of View (FOV) and Fog of War (FOW) systems for Unity. Leveraging the power of the GPU, it stands out as a high-performance solution that offers exceptionally efficient field of view system. FOV mapping has the following strengths.

1. High Performance - Running on the GPU, FOV mapping does not enforce the CPU to check the visibility of each pixel, nor does it fire numerous rays toward all directions. You can increase the number of units as you want without sacrificing the performance. FOV mapping can handle sights of hundreds of units at once.

2. Terrain-Adaptiveness - FOV Mapping can deal with terrains with highly variative elevation. With FOV mapping, you will find the fog of war harmonizes with your own terrain in a seamless manner.

3. Rich Features - FOV Mapping provides various functionality to make your intention feasible. You can fine-tune the property values to adjust the visibility of enemy, sight range, and even precision of the FOV maps. Moreover, FOV Mapping not only supports the Unity built-in render pipeline, but also the Universal Render Pipeline (URP), which is widely used across the gaming industry nowadays.

Originally intended for real-time strategy games characterized by expansive environments, FOV Mapping's optimization enables smooth and seamless experiences in large-scale scenarios. Although it was optimized for real-time strategy (RTS) with a massive volume, it can also be applied to various other projects seeking to incorporate a field of view system without compromising performance.
