Do you think the objects created in the following Representation Schema are always valid? Justify your answers with examples.

(i) Wireframe

(ii) Sweeping technique

(iii) CSG

(iv) B-Rep

1. Why do we call a CSG-tree as the binary tree?

2. What types of objects can be represented using the CSG-Schema? What are the limiting factors?

3. What are the conditions for valid object representation in the CSG Schema?

4. What are the differences between a wireframe model and a B-Rep model of a 3-D object?
