title Entre béziers e nurbs: Ensino de formas livres no contexto arquitetônico [Between Béziers and Nurbs: Teaching Free Forms in an Architectural Context]

summary This work intends to contribute to the use of techniques to represent free forms in didactic activities. It enlarges a previous study using only one technique to represent parametric curves and surfaces. It includes the NURBS technique, without discharging the BEZIER technique used before. Some exercises were structured using both techniques to model a representative example of Architecture: the Ronchamp Chapel . architect Le Corbusier. The tasks were compared to highlight the knowledge elements existing in both activities and its necessity of enlargement to move from one to another. Its is observed that the use of different techniques, as NURBS and Bezier, emphasize the specific characteristics of the geometric entities, establishing the control of parameters for free forms in the context of architectural graphics.
