3D Terrain Engine with Perlin Noise in Processing

Inori · 08-19-2016, 12:27 AM

First off, I'm going to continue to stress how awesome this environment is. 3D rendering is a piece of cake, graphics in general as easy as hell, and it's the simplest thing on earth to debug when things don't work. Anyway, onto this.

Spoiler: sourceCode:
int cols,rows,scl=20;
float[][] terrain;
float fly=0;

int varHeight=70;

void setup(){
	size(800,500,P3D);

	cols=round(width*3/scl);
	rows=round(height*2/scl);

	terrain=new float[cols][rows];
}

void updateTopograph(){
	float yOff=fly;
	for(int y=0;y<rows-1;y++){
		float xOff=0;
		for(int x=0;x<cols;x++){
			terrain[x][y]=map(noise(xOff,yOff),0,1,-varHeight,varHeight);
			xOff+=0.1;
		}
		yOff+=0.1;
	}

	fly-=0.05;
}

void drawMap(){
	fill(0,150,0);

	translate(width/2,height/2);
	rotateX(PI/2.5);
	translate(-width*1.25,-height*1.25);

	for(int y=0;y<rows-1;y++){
		beginShape(TRIANGLE_STRIP);
		for(int x=0;x<cols;x++){
			vertex(x*scl,y*scl,terrain[x][y]);
			vertex(x*scl,(y+1)*scl,terrain[x][y+1]);
		}
		endShape();
	}
}

void draw(){
	background(0,115,255);
	lights();

	updateTopograph();
	drawMap();
}

That is really good. I like this!

I can't even tell if you're being sarcastic or not Tongue

It is really interesting that you managed 3D in Java though, that kind of stuff has always scared me away.

I normally abhor Java, but I love Processing.
