Example 1 with Object3DSurface

use of mcib3d.geom.Object3DSurface in project mcib3d-core by mcib3d.

the class Mesh method computeConvexHull3D.

public ArrayList<Point3f> computeConvexHull3D() {
    QuickHull3D hull = new QuickHull3D();
    System.out.println("Computing 3d convex hull...");
    Object3DSurface o = new Object3DSurface(vertices);
    ArrayList<Voxel3D> pointsList = o.getContours();
    Point3d[] points = new Point3d[pointsList.size()];
    for (int ve = 0; ve < points.length; ve++) {
        points[ve] = new Point3d(pointsList.get(ve).getX(), pointsList.get(ve).getY(), pointsList.get(ve).getZ());
    }
    System.out.println("done 1st for");
    hull.build(points);
    hull.triangulate();
    ArrayList<Point3f> convex = new ArrayList<Point3f>();
    int[][] faceIndices = hull.getFaces();
    Point3d[] verticesHull = hull.getVertices();
    for (int k = 0; k < faceIndices.length; k++) {
        for (int ve = 0; ve < 3; ve++) {
            Point3d point = verticesHull[faceIndices[k][ve]];
            convex.add(new Point3f((float) point.x, (float) point.y, (float) point.z));
        }
