Brief
I was challenged to break a icosahedron in After Effects and make each piece of triangle explode following physical principle. After creating it with expression n After Effects, I challenged myself to do similar thing inside Houdini. The two tools have a different ways to approach the same effect, which gives me new knowledge of the logic for different tools.
After Effects
To start, I build the icosahedron manually to allow better control on each piece.
Then I created 5 slider to give more control of the explosion.
I used Chatgpt to create expressions on Position and Orientation to make the pieces move randomly while looking realistic.

The Controllable Polyhedron
With the Plantonic Solid inside Houdini, I was able to create a polyhedron much easier than in After Effects. The Facet and Normal SOP enable to break the obejct into pieces, the Attribute Wrangle was able to move hte pieces. By creating a explosion tool with script provided by AI, I was able to control the amount of explosion by he amount slider.
