1. Tiling halves triangle count. When texture atlas is one dimensional (1x256 instead of 16x16, http://i53.tinypic.com/34tbdeh.jpg), textures can be tiled in one direction.

See http://notch.tumblr.com/post/176620207/i-rewrote-the-tesselator.

This was an early test. Three top faces can be tiled into one. (Front faces too)

Side effect: game sees multiple rail blocks and tries to tile, so this ramp is created. This bug is nice because such ramps were planned. (however bug only works in one direction).


2. In previous versions fog wasted a lot of view range. Blocks hidden in fog were rendered anyway.
Current view range 32 is the comparable to previous 64. Even fog range 16 works, with 3k-6k triangles used - a software renderer could handle that.

I don't remember why, but fog color had to be changed to blue (to sky color).

Compare triangles used: (in reality the improvement is just 3x-5x because OpenGL display lists perform their own view frustum culling anyway, at least on Geforce 7600GT)


3. CPU usage is 5x-10x lower. This was done by replacing OpenGL immediate mode calls with vertex arrays, caching, replacing Lists with arrays, and using some better algorithms.

So in your experience, vertex arrays are better than lists?

Also, I wonder why the front page is not updated anymore
The last post there is July 28th...

I mean replacing List<int> with int[] It's at least 2x faster. And yes, i should have been replacing immediate mode with MeshBatcher (display lists), not with vertex arrays.

Front page is not updated because there are no new versions. (only 2010-08-19 is missing from the page).

Ah, I see.

Seriously, this is worse then the Minecraft posts.

Hello Mr. Exe. This is a blatant copy of minecraft and I suggest you delete it now before I refer to drastic measures. Fear me.

Oh yes one more thing, stop stealing the formulas from notch. I will kick your ass mentally and personally if you keep doing this.
P.S. tell your mother ragnatas says "hi". Fear me.

Hi exe, my name is markus. I've been seeing some of your work and I absolutely love it! I just wanted to help you out a little bit via this cool program called team viewer! I was gonna give you some codes and files via team viewer. It's also free! So when you get it. Send me a PM or reply to me showing me your team viewer ID and password (it's required to get the veiwer working). You can trust me. I live in Kelowna BC, Canada 711 Glenburn St. Nobody that was suspicious would give out there personal info like that right? Please pm me as soon as possible.

It's a trap!

Hey Markus you little fag! Guess what? If you keep putting this faggy butt-buddy posts I will hack your dumbass! You got me? Gtfo asshole! Fear me
