New file format, GWG

In order to write my new program, here is a new file format, called "GWG", or Geometric World Geometry. Here is it's format:

The file starts with two long's, telling the width and height of the data. Following is a byte telling what kind of storage we use for data: 0x00 for byte, 0x01 for short, 0x02 for int, and 0x03 for long. The rest of the file is the data. The whole file is GZipped to save space.

What is this file used for?
The file is made for my terrain generator for Minecraft. It is basically a heightmap, and can therefore be used for anything from terrain imagery to video game levels. I will release an API one of the coming days.

Announcing a new side project!

I have wanted to make a shooter since over half a year. In fact, i wrote my starterkit for that purpose. And it looks like that is reality now. Announcing a new game engine i will be working on: (unnamed). It is going to be a game engine. It will be cool. I am designing it to work well with big maps, many weapons, and wehicles. WOO!!!

World gen/decoration, eh?

Do you remember this summer, when i made a program that makes Minecraft worlds out of bitmaps? Of course you don't, i only posted it on facebook(why did i do that, and not here...). Anyways, it takes a heightmap, and converts it into a Minecraft map! Woo! Now, while being bored in class today, i got a genious idea, after lurking the internet for real world data. I found this: Height map of the world. They have it in three resolutions. One, that is 5400x2700, or 14 000 Square kilometers when converted. Of course, i don't think that is big enough, it is only 1/35000~th of the earth's size, so i am scaling down earth by a big amount. I wanted to go bigger, after all, i have the storage and computing power to do it on my server over night :D. The next size up is 21600x10800. That is consitherabily larger, in fact, it is 233280 square kilometers, or 1/2200th of earth, which is consitherabily larger, but still, size matters. I could just scale up the image 2200 times and use blur to estimate the new datapoints, but i found something better: 86400x43200. That is 3732480 square Kilometers, or 1:136 of the earth. The plan is to generate the entire map of the earth in the largest scale i can do with the RAM in my servers, i dont really want my pc with 8x the ram staying up all night, to generate the biggest Minecraft map ever made. Then, while generating, i will add terrain features, such as trees, and ores, to the map. Then, i will save it, and upload it somewhere. This will be fun.
EDIT

I did some new calculations, and the figures are smaller then i expected. This is because of me being me, and not remembering that 1000 m^2 != 1 km^2. Damn. The biggest heightmap is "only" 136 000 times smalller then the earth. Fuck :(. Oh well, some interpolation should fix it... Also, i calculated the map size from my current heightmap. It turned out to be 291 GB. Woah!
