Eihort is an OpenGL world renderer whose primary feature is a really long view distance. With a powerful GPU, you'll be able to see well beyond 1 kb (kiloblock) with a good framerate, even in a world with complex geometry.
The program is named after the deity invented by Ramsey Campbell within HP Lovecraft's Cthulhu mythos. Eihort lives in a network of tunnels deep beneath the ground, as do I when I play Minecraft.
Here are some key features of "Eihort":
· Mostly accurate rendering of your Minecraft world
· Smooth lighting similar to the real lighting engine
· Extreme view distance
· Biome colouring (you will need this)
· Semi-realistic day/night cycle.. no sun and moon yet though
· Switch between the Nether and the Overworld
· Move the single player spawn point and/or player position
· Highlight many different kinds of blocks, including underground ores, dungeons, railways, etc..
· Monitors the world directory for changes and updates affected chunks (watch yourself dig/build)
