Animate a 3D Cube and Triangles
Problem Statement:
In 3D graphics, more complex shapes are usually created using triangles. A triangle is a simple polygon and the vertices of a triangle will always be co-planar. Other objects can be split into triangles, so using triangles to create complex objects is an efficient method. The pre-placed blocks draw a cube with 6 triangles in 3 different shades of blue. Add a loop to animate the triangles moving away from the center and another to animate them moving back into a cube.
