Abstract: In various embodiments, a sketching application generates models of three-dimensional (3D) objects. In operation, the sketching application generates a first virtual geometry based on a first free-form gesture. Subsequently, the sketching application generates a second virtual geometry based on a first constrained gesture associated with a two-dimensional (2D) physical surface. The sketching application then generates a model of a 3D object based on the first virtual geometry and the second virtual geometry. Advantageously, because the sketching application generates virtual geometries based on a combination of free-form and constrained gestures, the sketching application efficiently generates accurate models of detailed 3D objects.
