Hello!
I have the following code that I found on the web to make 3D Voronoi, how can I export to Obj? Can anyone please help?
import wblut.processing.*;
import wblut.hemesh.creators.*;
import wblut.hemesh.core.*;

float[][] points;
int numpoints;
HE_Mesh container;
HE_Mesh[] cells;
int numcells;
WB_Render render;
void setup() {
size(800,800,OPENGL);
hint(DISABLE_OPENGL_2X_SMOOTH);
hint(ENABLE_OPENGL_4X_SMOOTH);
smooth();
//create a container mesh
container=new HE_Mesh(new HEC_Box().setWidth(400).setHeight(400).setDepth(400));
//generate points
numpoints=200;
points=new float[numpoints][12];
for(int i=0;i<numpoints;i++) {
points[i][0]=random(-250,250);
points[i][1]=random(-250,250);
points[i][2]=random(-250,250);
}
// generate voronoi cells
HEMC_VoronoiCells multiCreator=new HEMC_VoronoiCells();
multiCreator.setPoints(points);
// alternatively points can be WB_Point[], any Collection<WB_Point> and double[][];
multiCreator.setN(190);//number of points, can be smaller than number of points in input.
multiCreator.setContainer(container);// cutoff mesh for the voronoi cells, complex meshes increase the generation time
multiCreator.setOffset(0);// offset of the bisector cutting planes, sides of the voronoi cells will be separated by twice this distance
multiCreator.setSurface(false);// is container mesh a volume (false) or a surface (true)
multiCreator.setCreateSkin(true);// create the combined outer skin of the cells as an additional mesh? This mesh is the last in the returned array.
multiCreator.setUseDummy(false);
// can help speed up things for complex container and give more stable results. Creates the voronoi cells for a simple box and
// uses this to reduce the number of slicing operations on the actual container. Not fully tested yet.
cells=multiCreator.create();
numcells=cells.length;
render=new WB_Render(this);
for (int i = 0; i < numcells; i++) {
HEM_Lattice lattice = new HEM_Lattice().setWidth(26).setDepth(6);
cells[i].modify(lattice);
}
}
void draw() {
background(255);
directionalLight(255, 255, 255, 1, 1, -1);
directionalLight(127, 127, 127, -1, -1, 1);
translate(400, 400, 0);
rotateY(mouseX*1.0f/width*TWO_PI);
rotateX(mouseY*1.0f/height*TWO_PI);
drawFaces();
drawEdges();
}
void drawEdges(){
smooth();
stroke(0);
for(int i=0;i<numcells;i++) {
render.drawEdges(cells[i]);
}
}
void drawFaces(){
noSmooth();
noStroke();
fill(255);
for(int i=0;i<numcells;i++) {
render.drawFaces(cells[i]);
}
}
