Why are shiny objects not suitable?
Shiny objects act like a mirror and give strong reflections. When you look in a mirror, the objects you see reflected have the appearance of being behind the mirror. For the same reason the camera sees the reflections as behind the true surface which results in a model with a deep ‘hole’ as shown on the right. Note though that In the model shown in the figure on the right, only the strong reflection on the left has caused a ‘hole’. There is sufficient surface detail in the weaker reflection to allow the Scanner to form a correct surface. In some cases it may be possible to arrange the lighting or the subject itself to reduce the reflections to get a good Model.
