Aaron Winter b65ec82d46 Frustum Culling (for Sprites) (#1492) ... This PR adds two systems to the sprite module that culls Sprites and AtlasSprites that are not within the camera's view. This is achieved by removing / adding a new `Viewable` Component dynamically. Some of the render queries now use a `With<Viewable>` filter to only process the sprites that are actually on screen, which improves performance drastically for scene swith a large amount of sprites off-screen. https://streamable.com/vvzh2u This scene shows a map with a 320x320 tiles, with a grid size of 64p. This is exactly 102400 Sprites in the entire scene. Without this PR, this scene runs with 1 to 4 FPS. With this PR.. .. at 720p, there are around 600 visible sprites and runs at ~215 FPS .. at 1440p there are around 2000 visible sprites and runs at ~135 FPS The Systems this PR adds take around 1.2ms (with 100K+ sprites in the scene) Note: This is only implemented for Sprites and AtlasTextureSprites. There is no culling for 3D in this PR. Co-authored-by: Carter Anderson <mcanders1@gmail.com>		2021-03-24 21:29:53 +00:00
