Mixing
Multidimensional Array to path
0
Hi I have a multidimensional array of 1ns and 0es. the 0es are ordered into a mass that I wish to extrude into a shape using 3js. Unfortunately to extrude 3js requires a path when defining a shape object not a multidimensional array. I am using JQuery and 3js.
E.G.
[0,0,0,1,0,
0,0,1,1,0
0,1,1,0,0]
to become
moveTo(X,Y)
lineTo(X,Y)
so on and so forth
I am using this to auto generate a cave system.
this is my current attempt
function toPath(array){
for (var i=0;i<array.length;i++){
for (var j=0;j<array[i].length;j++){
if (array[i][j]===0 && countAliveNeighbours(array, i, j)>0){
points[i+":"+j]=[false,false,false,false];//lurd
if ((i+1)>0 && (i+1)<array.length){//right
if (array[i+1][j]===1){
points[i+":"+j][2]=true;
}
}
if ((i-1)>0 && (i-1)<array.length){//left
if (array[i-1][j]===1){
points[i+":"+j][0]=true;
}
}
if ((j+1)>0 && (j+1)<array[i].length){//down
if (array[i][j+1]===1){
points[i+":"+j][3]=true;
}
}
if ((j-1)>0 && (j-1)<array[i].length){//up
if (array[i][j-1]===1){
points[i+":"+j][1]=true;
}
}
}
}
}
return points;
}
var template=toPath(array);
var caveBase = new THREE.Shape();
for (var property in template){
var points=property.split(":");
var X=points[0]*3;
var Y=points[1]*3;
caveBase.moveTo(X,Y);
var directions=template[property];
if (directions[0]){caveBase.moveTo(X-1,Y+1);caveBase.lineTo(X-1,Y-1);}
if (directions[1]){caveBase.moveTo(X-1,Y-1);caveBase.lineTo(X+1,Y-1);}
if (directions[2]){caveBase.moveTo(X+1,Y+1);caveBase.lineTo(X+1,Y-1);}
if (directions[3]){caveBase.moveTo(X-1,Y+1);caveBase.lineTo(X+1,Y+1);}
}

You need to add your expected result with details. i. e. instead ofXandYyou should provide the exact values you are expecting based on the input array. You also need to include the code you tried so far.
