Square Hits Wall and Breaks into Small Triangles

Overview

A short animation shows a square whose diagonal is 5 cm moving toward a vertical wall, colliding, and shattering into many small right‑angled triangles that scatter outward. The key takeaway is the visual transformation from a single geometric shape to a collection of smaller triangles, illustrating fragmentation.

Phases

#	Phase Name	Duration	Description
1	Intro	~3s	Title fades in at the top. A square with diagonal 5 cm appears centered, its side length $\displaystyle s = \frac{5}{\sqrt{2}}$ cm is shown briefly as a faint label.
2	Approach	~4s	The square translates horizontally toward a solid gray wall on the right edge of the screen. A subtle motion‑blur emphasizes speed.
3	Impact	~2s	The square contacts the wall, briefly deforms (squashes) to convey impact, then a burst of particles appears at the contact line.
4	Fragmentation	~6s	The square instantly splits into dozens of small right‑angled triangles (all similar to the original). Triangles fly outward in radial directions, some sliding along the wall, others falling downward, fading as they move.
5	Outro	~3s	Remaining triangles settle into a static mosaic on the floor. The title re‑appears with a brief caption "From one square to many triangles" and then fades out.

Notes

• All animations are kept concise; total runtime ≈ 18 seconds, well under the 30‑second guideline.
• No textual labels are placed on individual triangles; the visual effect alone conveys the fragmentation.
• The wall is a simple vertical rectangle with a matte finish to contrast with the bright square.
• Triangles are generated with random orientations but maintain the same size ratio as the original square’s half‑diagonal, ensuring visual consistency.
• The scene uses a single Manim Scene class; no additional scenes are required.
• Fade‑in/out transitions are linear and short (≈0.5 s) to keep the pacing brisk.
