Advantages

• It is hard to model out door scenes
• The complexity of geometric modeling is high
• It is hard to render large number of polygons at
  interactive rates.

Drawbacks

• Hard to extract geometric information from images
• Invisible information is missing
• Image-Based Modeling Often require large storage
