Perlin Noise

[Pew44Six]

Hiya.

I was wondering if it's possible to generate a terrain map with Perlin Noise in Torque. And if it is, how to do it.

Thank ya :D

I also have the source of Torque 3D if I need to do some kind of C++ stuff.

Blockland runs on TGE, so that won't work.

As far as I know, TGE doesn't even have height map importing at all.

so no.

1. Badspot has never accepted foreign C++ code.
2. Why can't you just do a cubescape?

Well I was wondering how Minecraft worked with terrain, and I figured Perlin noise had something to do with it, and I just don't know how to actually do Perlin Noise in Torque. Also I was planning on doing this with T3D, just as a practice project.

if you can make a height field (gray-scale bitmap) - then you can import that into the mission editor.  or if you want it made out or bricks -- just write your own .bls file and load that.

See, thats what I was wondering, is if you can make a "height field" directly in Torque.

minecraft generates terrain with complex algorithms.

meaning - can you make a .bmp file directly from TorqueScript?  I highly doubt it.

but theres nothing stopping you from creating bricks

Badspot has used code provided by Ephi.

Well I have no idea how to save a height field or create a terrain file, but I did make this just recently:
http://dl.dropbox.com/u/551734/dev/torque/perlin.cs (full code page stretches)
It's based off of this: http://mrl.nyu.edu/~perlin/noise/ and this: http://code.zack0wack0.com/jscraft/js/ImprovedNoise.js

Here's the code I used to test it:

Code: [Select]

function serverCmdPerlinTest(%client,%width,%length,%depth,%iters)
{
	if(!%client.isSuperAdmin || !isObject(%client.player))
		return;
	%ppos = %client.player.getPosition();
	%px = getWord(%ppos,0);
	%py = getWord(%ppos,1);
	%pz = getWord(%ppos,2);
	if(!%iters)
		%iters = 4;
	%perlin = new ScriptObject()
		{
			class = perlin;
		};
	%size = %width * %length;
	%quality = 2;
	%z = getRandom() * %depth;
	for(%j=0;%j<%iters;%j++)
	{
		for(%i=0;%i<%size;%i++)
		{
			if(%data[%i] $= "")
				%data[%i] = 0;
			%x = %i % %width;
			%y = mFloor(%i / %length);
			%data[%i] = %perlin.noise(%x / %quality,%y / %quality,%z) * %quality;
		}
		%quality *= 4;
	}
	for(%x=0;%x<%width;%x++)
	{
		for(%y=0;%y<%length;%y++)
		{
			%bx = %px + (%x * 2);
			%by = %py + (%y * 2);
			%bz = %pz + mFloor(%data[%x + %y * %width] * 0.2);
			%bpos = %bx SPC %by SPC %bz;
			%brick = new fxDTSBrick()
			{
				position = %bpos;
				datablock = brick4xCubeData;
				isPlanted = 1;
				client = %client;
				colorID = 2;
			};
			%brick.setTrusted(1);
			%brick.plant();
			%client.brickGroup.add(%brick);
		}
	}
	%perlin.delete();
}

That is pretty awesome. So I don't even need a height field to make terrain?

You're making a mod for a game about building with bricks and your first instinct is to use something other than bricks to make terrain.

What.

Man, now I'm interested in Perlin Noise.

I'm probably going to mess around with this a bit in the near future.
