Excerpt of article text...

It's Christmas time! This time I want to show you how you can animate your own turn-around Christmas tree in Xojo. We then also want to decorate the tree.

We will use the functions from the MBS Xojo SceneKit Plugin. Before we start, first we need to think about what our tree should look like. For the sake of simplicity, we will limit this example to the basic SceneKit figures from which we want to build the tree. We have spheres, plates, boxes, truncated cones, capsules, cylinders, tubes, and pyramids to build the tree from (see Figure 1).

The tree is made of fir greenery and a trunk. The trunk is simply a cylinder. On top of it we have two truncated cones and a whole cone on top. On the tree hang Christmas baubles (spheres) and on the top is a star consisting of a sphere and six pyramids that form the prongs of the star.

Before we can see anything in our project we have to position the SCNControlMBS on our window. We then additionally create the properties MyScene as SCNSceneMBS and MyView as SCNViewMBS. We write our code in the Open event of the control. There we first assign the values to the properties:

MyView = Me.View
