Tension-Active Form is a three-dimensional shaping method that Lyu has been exploring since 2018, and it was further deepened and expanded during his doctoral studies from 2022 to 2025. This technique applies tensile forces to planar materials—such as paper, thin wooden sheets, or woven fabrics with low elasticity—causing them to deform under tension and transform from a two-dimensional surface into a three-dimensional form. The resulting structures not only possess self-supporting strength but also exhibit inherent transformability. By altering the internal node connections, the form can shift between different dimensional states.

The creativity and spirituality behind Tension-Active Form are rooted in Lyu’s childhood faith. He believes that the universe was stretched out like a great canopy by God (Isaiah 40), with abundant life unfolding upon it. Although invisible to the naked eye, tensile forces are omnipresent in shaping the world around us—the spider’s web, the trembling wings of insects, the deformation of the earth’s crust, the undulation of water surfaces. The humble yet powerful nature of tension—always present yet hiding itself—draws Lyu to seek the Creator behind it, whose character reflects the same quiet strength.

Lyu continues to explore the possibilities of Tensioned Forming and has already developed multiple outcomes, including Tension Modules, Tension Canvas, and Tension Pleats.

張拉造型是Lyu從2018年開始所探索的立體造型手法，之後在2022年至2025年的博士課程期間得到了更深入的研究和拓展。張拉造型手法是運用張拉力對平面材料（例如紙、薄木板、編織佈等低彈性的平面材料）進行張拉變形，使之從二維平面產生三維變形的方法。這種方法製作的立體形狀擁有自立的結構强度的同時，也具有可變形的特徵。改變内部節點的連接方式，就可以使形狀產生在不同維度之間的變化。

張拉造型的創意和精神性根植於Lyu從小的信仰，他相信宇宙就像是上帝張拉一張幔子一樣鋪展開來（以賽亞書40章），豐富的生命躍然其上。張拉力在我們生活的世界雖然肉眼不能見，但他在塑造世界的背後無處不在。蜘蛛的網、昆蟲抖動的翅膀、地殼的變形、水面的起伏… 張拉力的這種隱藏自己但又强大的特性，吸引著Lyu對他背後的那位有同樣性情的造物主的追尋。

Lyu在持續探索著張拉造型的可能性，目前已經發展出了張拉模塊、張拉畫布、張拉皺褶等多樣成果。
