Download GPU Line of Sight / Field of View visualization FREE Unity
Description
A line of sight system visualizes which parts of the game world can be seen from the standpoint of for example a 3rd person in-game character. The area outside of the line of sight is obscured and remains hidden from the player.
This system was developed as an alternative to CPU based line of sight visualizations. CPU based systems use a combination of ray casting and dynamic meshes to compute the line of sight and are often CPU intensive, causing a serious impact on performance.
This new GPU based line of sight system uses a technique very similar to shadow mapping and is significantly faster than any CPU based system, freeing up valuable CPU time. It has been designed from the ground up with performance, ease-of-use and customizability in mind. The effect can be tweaked to achieve any desired visual style. The user can control the look of the effect by selecting which image effects are applied to the area outside of the line of sight. It is perfectly suited for top-down stealth or action games, but also works from other viewpoints and in other type of games.
This system is compatible with both the forward and deferred rendering pipelines and supports DX11. Because this system makes heavy use of render textures, it is currently not supported on mobile platforms.
