Urban DuoA Stylized Animation Comparing Longchang Apartment and the City of Shanghai


Overview
Shanghai is a fast-paced, highly modernized city. However, the Longchang Apartment within it stands out for its distinctive, nostalgic environment, rich everyday atmosphere, and warm, close-knit relationships within the neighborhood. 

I created a six-minute stop-motion-style animation using 3D techniques. Through cubic compositions and dual-screen parallel storytelling, it contrasts the living environment, interpersonal relationships, and attitudes toward life between Longchang Apartment and the broader city of Shanghai.




Previous Work
In 2023, I created the short animation Miniworld, which allowed me to explore stop-motion–style rendering techniques in advance and led me to the theme of Longchang Apartment.

InspirationPassing by Longchang Apartment, I was struck by its vivid sense of everyday life. The old furniture and warm interactions among neighbors made me feel as if I had stepped back into the last century. In a time when urban relationships are increasingly distant, this atmosphere feels especially precious.






Why does Longchang Apartment look like it was forgotten in the last century?Over time, long-term tenants maintained their old habits while compressing unused items into space-saving cube forms. As the population continued to grow, limited space led private areas to gradually encroach upon public corridors. Push open a door, and countless cube-shaped bundles and scenes of everyday neighborhood life unfold, creating a unique living landscape reminiscent of the last century.







What's so special about life at Longchang Apartment?Blurring the boundaries between private and public space, Longchang Apartment fosters a unique living landscape that shapes residents’ lifestyles and ways of thinking. In Shanghai’s fast-paced urban environment, social ties have grown increasingly distant. Even so, Longchang Apartment, located right in the city, continues to preserve the spirit of old lane culture, characterized by frequent interactions, familiar faces, and warm neighborly bonds. Here, residents lead calm and grounded lives, placing greater value on human connection than on status or wealth.

Technical Details Stop-Motion Stylized Rendering
The vintage, simple, and humanistic stylized effect of stop-motion animation aligns perfectly with the nostalgic atmosphere of Longchang Apartment. By researching stop-motion materials and conducting extensive stylized rendering tests, I developed a 3D technical workflow to recreate realistic stop-motion scenes and frame-skipping effects.
Geometric Spatial Transition
The animation adopts an orthographic perspective, with transitions between selected shots. By transforming cubes geometrically to bridge two scenes, it produces transitions that resemble spatial illusions. Each transition is created in a separate project file containing the start and end frames of the incoming and outgoing scenes.
