I need to build terrain using one cube with dimensions 1x1x1, the coordinates are provided in a .txt file and there are about 11M triplets.The problem is that using my current code I can only draw about 60k of them, then the browser tab is resetted and a prompt to stop an unresponsive script comes out, so I use too much memory and time to generate them.Here is the chunk of code I use to draw them:function generateCubes(data) {    var cubeGeometry = new THREE.CubeGeometry(cubeSize, cubeSize, cubeSize);    var material = new THREE.MeshLambertMaterial({color: 0x587058});    var mesh = new THREE.Mesh(cubeGeometry, material);    var mergedGeo = new THREE.Geometry();    var instance;    var line = data[0].split(';');    var translateX = line[0], translateY = line[1], translateZ = line[2];    //var group = new THREE.Object3d();    for(var i = 0; i < 100000; i++) { // should go to data.length        line = data[i].split(';');        //instance = mesh.clone();        //instance.position.set(line[0] - translateX, line[2] - translateZ, line[1] - translateY);        //group.add(instance);        mesh.position.x = Number(line[0]) - translateX;        mesh.position.y = Math.round(Number(line[2]) - translateZ);        mesh.position.z = Number(line[1]) - translateY;        mesh.updateMatrix();        mergedGeo.merge(instance.geometry, instance.matrix);    }    group = new THREE.Mesh(mergedGeo, material);    scene.add(group);}The function is called from a success in an $.ajax call.The commented parts are used without merged geometry, that way I can draw around 100k of the data.
