VideoTrace creates low polygon count models. The number of polygons in a model relates directly to the number of polygons you draw. That means that it’s most efficient to model objects with large planar surfaces. Curved objects can easily be modelled, however, by breaking them up into segments. That’s what is going to happen in the end whatever method you use, as everything is modelled as triangles in the end. it’s just a question of how many triangles.
The following example shows the modelling of a curved object using this method:
