3D lettering, as a design style, involves the creation of letters in three-dimensional form, giving them depth, texture, and a life-like quality. This technique enhances the visual appeal of text, making it more engaging and interactive. In China, where calligraphy and characters hold profound cultural importance, the integration of 3D elements into lettering serves not just an aesthetic purpose, but also revitalizes traditional art forms by merging them with contemporary visual language.
