Abstract: It is proposed a computer-implemented method for designing a three-dimensional modeled object, wherein the method comprises the steps of: user-interacting with a screen; defining a stroke corresponding to the user-interacting; discretizing the stroke into a set of points; projecting the set of points onto at least one support in a three-dimensional scene; constructing the three-dimensional modeled object from the projected set of points and the said at least one support.

Abstract: An apparatus and a method for using 3D animated icons to preview transformations related to 3D models are disclosed. The apparatus includes a graphical user interface (GUI) which includes a visual depiction of the 3D model as well as a cursor and 3D animated icons which are representative of various transformations that may be performed on the model. The animation of the 3D icons provides the user with a preview, before selecting the icons, of what will happen to the 3D model depicted in the GUI if the transformations are in fact applied by user-selection of the icons. The method includes displaying, on a GUI, a 3D model as well as a cursor and at least one 3D animated icon which displays a representation of a respective transformation. The method further includes changing the state of an animated icon from static (i.e., a still frame) to animated when the user positions the cursor in the neighborhood of the icon, thereby illustrating the effect of the transformation.
