 # What is Distant Horizons?

-Distant Horizons is a Minecraft mod that adds a Level Of Detail (LOD) system to\
-render simplified chunks outside the normal render distance\
-allowing for an increased view distance without harming performance.
+Distant Horizons is a mod which implements a [Level of Detail](https://en.wikipedia.org/wiki/Level_of_detail_(computer_graphics)) system to Minecraft.\
+This allows for far greater render distances without harming performance by gradually lowering the quality of distant terrain.

-In other words: this mod lets you see farther without turning your game into a slide show.\
-If you want to see a quick demo, check out a video covering the mod here:
+Below is a video demonstrating the system:

 ## Switching Versions

 To switch between different Minecraft versions, change `mcVer=1.?` in the `gradle.properties` file.

-If running in an IDE, to ensure the IDE noticed the version change, run any gradle command to refresh gradle. (In IntellJ you will also need to do a gradle sync if it didn't happen automatically.)
->Note: There may be a `java.nio.file.FileSystemException` thrown when running the command after switching versions. To fix it, either restart your IDE (as your IDE is probably locking a file) or use a tool like LockHunter to unlock the linked file(s). (Generally it is a lib file under `common\build\lib`, `forge\build\lib`, or `fabric\build\lib`). \

+ * In general all MC rendering should go through MC's {@link GlStateManager},

+ * So, to prevent issues if a mod (or MC itself) calls a direct GL function
+ * instead of the {@link GlStateManager} wrapper, we need to be sure about what the actual

+ * This way whether a mod (or MC) is using the {@link GlStateManager} or direct GL calls,
