"Appeared and Left" is an early 3D-rendered animation project created during my undergraduate studies, inspired by Wong Kar-wai’s In the Mood for Love. This work explores nostalgia, longing, and the bittersweet emotions of separation, set against the backdrop of a meticulously crafted digital Hong Kong in its golden era. The project focuses on environmental storytelling, utilizing cinematic lighting, composition, and spatial design to evoke the dreamlike, neon-lit aesthetic characteristic of Wong Kar-wai’s films. Every detail, from the color palette to the atmospheric lighting, was carefully constructed to immerse the viewer in a world of fleeting encounters and unresolved emotions. By closely mirroring the visual and emotional depth of In the Mood for Love, this animation seeks to recreate the essence of an era—a city filled with whispers of unspoken words and missed opportunities. Through the fusion of architectural visualization, mood-driven cinematography, and narrative design, Appeared and Left serves as an experimental homage to classic Hong Kong cinema, capturing the melancholy of love and loss in a surreal, digitally reconstructed space.
