Producing the Kaleidoscope effect for the Animation

In my animation, there is a sequence where the camera flies through a series of tunnels where the walls are constantly shifting and changing in a way similar to a kaleidoscope.

To produce this technique I based my idea off a tutorial on Greyscale Gorrila which helps to produce stylized low poly images using Cinema 4D.

To begin with, I created a sphere object and changed the object properties to Icosahedron and unchecking render perfect. By changing the type to Icosahedron, The mesh changes to a triangular mesh which will help create the edges which make the low poly look so unique.






 This image shows what the mesh looks like. To view the object in this way go to the display dropdown and selected Gouraud Shading (Lines).

From here I went to the Create dropdown, selected deformer and then clicked on the Displacer deformer to create one.





I then dragged the displacer into the sphere and the mesh of the sphere changed into a less smooth, more deformed shape. Inside the shading submenu in object properties, I selected noise and manipulated the settings in a way which I thought looked the best.













Once I was happy with this step, I went into the deformer menu again and this time created a polygon reduction object which I placed inside the sphere with the displacer (but not inside it).

When I placed the polygon reduction inside the sphere, the sphere changed to a more basic version of the previous state, with reduced polygons making the edges and faces more basic and defined. The effect can be manipulated using the object properties in the polygon reduction object and by adjusting the reduction strength. I decided that the looks gained from using 50% strength looked how I wanted it to.










Now that I had a basic shape to work off, I created a crude 3 Tone gradient texture using very dramatic colouring and applied it to the object. This effect can be easily manipulated at a later date to make a better colour scheme.














Now I have the object I will be using for making the walls of the kaleidoscope tunnel, I could begin working on animating the object. First of all, I created a Symmetry object and placed the sphere inside it.


If the object hadn't been centred properly, I would move the sphere to ensure that the sphere was duplicated correctly. In this instance I made the Symmetry Object's Mirror Plane ZY, although this can be manipulated in future to get different results.

Selecting the MoGraph dropdown, I created a cloner object and placed the Symmetry tag inside.





Using the settings above, I manipulated the cloner until I had a flower like pattern with the object as each petal.
While creating these settings, I made sure to allow a hole through the centre of the "Flower".






Finally to animate this step, I basically just keyframed changed to the radius making the image shrink and grow, changing the colours of the kaleidoscope.

Once I have created several kaleidoscopes I intend on animating a camera to pass through the centre of the "Flower" into the next kaleidoscope and either looping indefinitely or slowly transforming into the next stage of my animation
