Immersive t hree - dimensional environments can give test users a valu- able first - person experience of design ideas . Trained designers can quickly create mock - ups using three - dimensional modelling software , but this task is very hard and time - consuming for individuals without three - dimensional modelling expe- rience. This paper presents a simple sketching strategy that allows simple two - dimensional panoramic sketches to be rendered in pseudo - three - dimensions us- ing panoramic viewers. This allows designers without three - dimensional model- ling experience to represent their design ideas that can be explored from single points in space. The paper explores the properties of the projections , and illus- trates how to represent spatial shapes.
