This was done in Proce55ing.

Some day, i will be able to finish it without going broke.
enjoy

indeed it works... after upgrading W2k to SP3 and reinstalling JRE 1.4.1_01 ..
a troble to be able to see it, but it's worth! great piece Josh!!
congrats!

In response to a private email, here are the two functions which allowed me to draw mountain fold and valley fold lines in the virtual origami project. With a little tinkering, you can accomplish any line stroke style seen in Adobe Illustrator -- and beyond.
---------------------
// Valley and Mountain folds
// by Josh Nimoy
// Based on Bresenham
// The valley line is just - - - - - - - - -
// The mountain line is fancier . _ . _ . _ . _ . _
// notes: for the "BApplet p5" argument, just pass "this" if you are working inside the Proce55ing software. Geometry.distance() is the pythagorean theorem.
public static void valleyLine(BApplet p5, int x0,int y0,int x1, int y1, int refX,int refY){
int dy = y1 - y0;
int dx = x1 - x0;
int stepx, stepy;
if (dy < 0) { dy = -dy; stepy = -1; } else {stepy = 1;}
if (dx < 0) { dx = -dx; stepx = -1; } else {stepx = 1;}
dy <<= 1;
dx <<= 1;
p5.point(x0,y0);
if (dx>dy) {
int fraction=dy-(dx>>1);
//int ogx0 = x0;
//int ogy0 = y0;
double d;
while (x0!=x1){
if(fraction>=0){
y0 += stepy;
fraction -= dx;
}
x0 += stepx;
fraction += dy;
d = Geometry.distance(refX,refY,x0,y0);
if(d%12 > 4)p5.point(x0,y0);
}
}else {
int fraction = dx - (dy>>1);
//int ogx0 = x0;
//int ogy0 = y0;
double d;
while (y0 != y1) {
if (fraction >= 0) {
x0 += stepx;
fraction -= dy;
}
y0 += stepy;
fraction += dx;
d = Geometry.distance(refX,refY,x0,y0);
if(d%12 > 4)p5.point(x0,y0);
}
}
}
public static void mountainLine(BApplet p5, int x0,int y0,int x1, int y1, int refX,int refY){
int dy = y1 - y0;
int dx = x1 - x0;
int stepx, stepy;
if (dy < 0) { dy = -dy; stepy = -1; } else {stepy = 1;}
if (dx < 0) { dx = -dx; stepx = -1; } else {stepx = 1;}
dy <<= 1;
dx <<= 1;
p5.point(x0,y0);
if (dx>dy) {
int fraction=dy-(dx>>1);
//int ogx0 = x0;
//int ogy0 = y0;
double d;
while (x0!=x1){
if(fraction>=0){
y0 += stepy;
fraction -= dx;
}
x0 += stepx;
fraction += dy;
d = Geometry.distance(refX,refY,x0,y0)%17;
if(d>9 || (d>3 && d<5))p5.point(x0,y0);
}
}else {
int fraction = dx - (dy>>1);
//int ogx0 = x0;
//int ogy0 = y0;
double d;
while (y0 != y1) {
if (fraction >= 0) {
x0 += stepx;
fraction -= dy;
}
y0 += stepy;
fraction += dx;
d = Geometry.distance(refX,refY,x0,y0)%17;
