Light problem when I load a file


Recommended Posts

Hey everyone,

First of all, sorry for my bad english, not my first language.

So, I'm doing this project, where I load a file, with some coordinates and colors, then I draw those on the canvas, just like this image:

And as you can see, I'm using the DAT.GUI to control the axis and the planes.
But here is my problem, when I load it, it goes really well, but when I unmark all 3 axis boxes, this happens:

All the objects have no light or color, sometimes it happens that it has color, but won't have light. This only happens after I load the file, if I unmark all 3 axis boxes on the beggining, nothing happens:

Also, if I unmark ALL boxes, including the plane ones, this happens:

Only one kind of cylinder with a sphere in the middle of it will show, and when i change camera position or rotation, those cylinder and sphere will change color, varying between the 3 axis colors and white.

When the file isn't loaded, everything works the way I want, also if I unmark all 3 plane boxes, it works perfectly

I really don't know what could be causing this problem, this is my text file I'm loading

NOTE: I start reading the file after the [ARESTAS] keyword (line 133 in this example), and basically is like this: X1 Y1 Z1 X2 Y2 Z2 R G B

This is how I'm reading the file:

var matrix = [];
var keyWord = '[ARESTAS]';

//Função para ler o arquivo
function readSingleFile(evt) {
	var f = evt.target.files[0];

	if (f) {
		matrix = [];
		var r = new FileReader();
		var contents = 'empty';
		r.onload = function(e) {
			contents = e.target.result;
			var pastKey = false;
			contents.split('\n').forEach(function(line, i) {
				if (pastKey) {
					var vals = line.trim().split(' ');
					if (vals.length > 2) {
				if (line.trim() === keyWord) {
					pastKey = true;
	} else {

document.getElementById('fileinput').addEventListener('change', readSingleFile, false);

window.addEventListener('DOMContentLoaded', function() {

function update() {
	//BABYLON usual settings


If all these informations are not sufficient, let me know, I have no problem sharing the other parts of the script, but I really think the problem happens when I read the file.

Thanks :]

In order to save all this work, since I still have to manage how do I use xhr properly, is it possible that this test can occur in my repository on github?

The file that I've been using is attached. It's really simple to use it, just click on the Menu button, and choose the file.

If it's not possible, then I need some time to manage how xhr works :)

File: TestCluster.s3d
