Computational modelling and simulation are core techniques for computer assisted textile fabric, and fashion design and manufactures. Realistic three dimensional computer visualisations of textile fabrics and cloth modelling are also important in many applications. For example, realistic computer generated （CG） cloth effects are key elements in 3D CG films, 3D computer games, and on-line cloth shopping. In this paper, we present recent advances in fabric modelling and its applications with focus on the development of suitable fabric models suitable for textile and cloth industries. We discuss problems, challenges and possible solutions for developing efficient and stable fabric drape models, which focuses on fundamental computational algorithms and methods. A new energy based approach is proposed in the paper for fabric material modelling. This approach is a natural choice for fabric materials engineering based on computational modelling techniques. It is also versatile, enabling easy adaption in 3D garment design. Furthermore, we propose a general scheme to identify and integrate fabric properties of real fabric materials for modelling complex dynamic deformation.
