ChristmasTree | ever wondered how to animate snow | Awesome List library

I have an exercise where I have to print a christmas tree.

I have a JTable that displays information from a Vector.Now I have to update the last column of the table periodically. For this I took a scheduler-thread and implemented it in the constructor of my main program. The code runs fine but the Table is not updating.It is showing the data which I entered starting. Please help.

My Main Program:

i am a real newbe in the world of helixtoolkit and Graphics 3D.

What i make:

I have the homework to code a programm which lets you decorate a christmastree with different types of decoration.

One type of decoration is a candle. The problem. The candle is too small in relation to the tree.

My question:

How can i resize my FileModelVisual3D inside of the view_tree with code behind?

I basically want to change the color of a JointJS shape in their RAPPID environment I'm trialing.

Here is some background on what I have so far and what I want to achieve: I have a JointJS shape called ChristmasTree that extends joint.dia.Element. Basically the svg string that builds this ChristmasTree object is a path of the tree (svg path element), and multiple ornaments on it (4 svg circles/ellipses which have id's and classes that I would assume I can use to modify the colors).

I set some initial values for the ornaments via the style attr inside the svg string. Once I place that in the left RAPPID menu, the user can drag that one Christmas Tree with red balls on it, yay. Question ###1: But I would like to place a 2nd ChristmasTree shape in the left menu without creating another main object that has Green balls... How would I achieve this? In my below code, christmas_tree_style_2 should override the .ornament class with 'fill': "#00ff00", but doesn't (in the left menu, its still red)? In fact, christmas_tree_style_1, i also tried to override with a Blue ball 'fill': "#0000ff", but its still red. How can I achieve a left-nav override of the shape?

Question ###2: Pretend you help me resolve previous issue. You can drag and drop 2 multiple color ChristmasTree's from the left-menu nav into the main RAPPID content area. I'd like to now change the colors dynamically through the inspector. I added a color inspector that shows up in the RAPPID right-nav menu for every element with: 'ornament_fill': { label: 'Color of christmas-tree-ornament's fill', type: 'color', group: 'generalinfo', index: 2 } But not sure how to create an event to dynamically change the color of the ornaments. Any idea? Thanks!

Here is the important part's of the code below.

And also here is an actual working example (but the left-nav initial override and right-nav Inspector color override dont work, hence my 2 questions): http://armyofda12mnkeys.kissr.com/rappid_christmastree/index.html (sorry i couldnt find a CDN for rappid.js to add to JSFiddle so it was easier to upload the folder to a site). The applicable files to my question are app.js and rappid-custom-shapes.js.
