A NullPointerException is raised in the findStyle(...) method of class com.sevenmap.data.styles.Styles, as the themes attribute is null and hasn't been instanciated. Please fix this as soon as possible, and edit the associated release (tag 0.3 3e1811b) as soon as possible @seba1204 .

When calling the show() or hide() methods on a Node, a ConcurrentModificationError is thrown, due to the children ArrayList being itterated on by the engine while it is modified by the Node itself.

To Reproduce
Steps to reproduce the behavior:

1. Schedule a task which hides or shows an object at runtime
2. Observe

Expected behavior
Obviously no Error being raised

Ray casting and colliders are necessary to get the corners of the screen's position

Créer les classes du diagramme de classe.

Create java classes to store objects that are quickly displayable.
This objects will be serialized in JSON and store in the database. Then they will be call by our programm to by diplayed in runtime.

These objects must comply with the following guidelines:

• Ne pas être trop "lourds"
• Contenir des éléments permettant des les trouver lors de recherches utilisateur
• Contenir des éléments permettant de les repérer dans l'espace facielement
• Etre le plus décomposé possible (en vertex)

• Créer un fichier *.geojson de test assez "simple", mais avec un maximum de cas différents
• Créer un fichier settings.json
• Mettre à disposition des fichiers de tests plus gros

Read the documentation @ https://www.lwjgl.org/guide
understand it and create a couple of test applications to get the hang of it.

Code some test classes for the team to use instead of modifying App.java.

Dans le but de faciliter et rendre plus propre la programmation des évènements liés aux interractions utilisateurs, il serait sympa de se faire notre propre handler.
Voilà comment à quoi il pourrait ressembler :

window.onEvent(Event.MOVE, (dx, dy) -> { });
window.onEvent(Event.ZOOM, (delta) -> { });

Les évènements Event.MOVE et Event.ZOOM peuvent par exemple être en dur dans un enum, ou plus dynamiquement dans une HashMap. On pourrait imaginer pourvoir faire évoluer l'API avec d'autres évènements comme Event.GetFocus, Event.LostFocus, ... à moins qu'il y ait d'autres endroits plus pertinents pour ça.

Il faudrait aussi que le callback renvoit des paramètres pertinents en fonction de l'évènement, quitte à créer un objet de retour exprès (comme vu en TD).

Describe the bug
undefined behavior (crash/graphical bug)

To Reproduce
Steps to reproduce the behavior:
if you reparent a node to the scene root, then reparent it to null, and reparent it again to the sceneRoot, the buildChildren() gets called twice causing an undefined behavior.

Expected behavior
obviously nothing

Keyword varying out in src/main/java/resources/Fragment.glsl is not recognized on some computers.

Create a logger class which will be used instead of the classic System.out.println() call.

As @seba1204 mentioned, we'll need a gui library for text, buttons, sliders etc... at some point. The incorporate-gui-library branch should add it.

When all data is computed (etiher from Geojson files or from OSM XML files/API) we have to store it. And we'll have to get this data very quickly in runiing time. Do not forget that data will be modified by registered users.

Advancement :

• create data base
• make installer files for database for Windows and Linux
• make tables to store and read data
• create another database (online) to store useraccounts

Actually all free maps are stored in the OSM XML format. So we have to handle it if we want to display some maps.

Advancement :

• Create great Java strucutre to handle XML parsed data
• Parse XML files
• Convert data to our objects that we can easly handle
• Implement OSM API

When we compute maps from OSM data, we have to convert a lot of differents objects (called map features). We have to handle the most important ones in order to have a nice display of maps.

Advancement :

• Handle the 10 most important features
• Handle the 20 most important features
• Handle the 50 most important features

When data is loaded from database, we need to compute it in order to make it readable by the 3D engine.

Advancement :

• Make simple vertex from Points
• Make simple vertex from Segments
• Make simple vertex from Polygons
• Make complex vertex from convex Polygons or Multiple Polygons
• Add some style based on data

fov and nearfar attributes should be inside the Camera, not the Window class. This needs to be fixed before implementing raycasts.

Change Vector3f to Color

This is the current Vertex constructor:

public Vertex(Vector3f position, Vector3f color, Vector2f textureCoord) {
        this.pos = position;
        this.color = color;
        this.textureCoord = textureCoord;
    }

I think, it could be a specific color class instead of a Vectof3f so people could create a Vertex with a color in Hex for example.
The class would take care of converting the color to the right format !
