This paper summarizes research progress of 3D style design based on sketching, especially focuses on 3D modeling method based on sketching, 3D stroke fitting. The future research direction on multi-strokes fitting and the use of digital pen pressure and other information for style design are proposed.

This paper reviews and demonstrates how to use digital technology to design the ecological environment. Through the analysis and summary of current research fields and status quo of eco-design, we explain the development of ecosystem design in life and building, and propose the key issues to be addressed, discuss the inadequacies of current research, and predict the next main research tendency of ecosystem design based on digital technology.
