Acquire Complete Versions Of Cylinder.h And Cylinder.cpp

Acquire complete versions of Cylinder.h and Cylinder.cpp from Part 1.

Complete add, display, and scale functions for Composite. Complete the Big-3 for Composite. Note that the Composite::allPolyhedra attribute is a vector of pointers (i.e., std::vector). I was feeling generous and provided you the Composite::operator= method (which I used the copy-and-swap idiom). This leaves you with the Copy Constructor and Destructor (the remaining parts of the Big-3). If you implement everything in Composite correctly, you will see:

  • PASSED->testDefaultConstructor
  • PASSED->testAdd
  • PASSED->testClone
  • PASSED->testRead
  • PASSED->testScale
  • PASSED->testDisplay

If you see FAILED, you must revisit the corresponding function(s). Many students forget to scale the bounding boxes. This can be done using the BoundingBox::scale or Polyhedron::scale functions.

Paper For Above instruction

The task revolves around completing a segment of object-oriented programming for polyhedral shapes within a geometric modeling context, specifically involving classes like Cylinder and Composite. The core objectives involve implementing key member functions to ensure proper object management, manipulation, and representation, adhering to principles of good C++ design, particularly with resource management and object copying semantics.

In this assignment, students are provided with templates for Cylinder.h and Cylinder.cpp, which they can utilize directly or modify according to their implementation. The main goal is to complete the methods for the Composite class—specifically add, display, and scale functions. These functions enable dynamic management of a collection of polyhedra, which are referenced via pointers in a vector. Proper handling of these pointers is crucial to prevent resource leaks and ensure deep copying, as required in the copy constructor, destructor, and assignment operator (operator=).

Implementing the Big-3 (destructor, copy constructor, and assignment operator) correctly in the Composite class is essential to manage the dynamic memory allocated for the polyhedra. The provided operator= employs the copy-and-swap idiom, which simplifies exception safety and strongly handles self-assignment. However, students must ensure the copy constructor and destructor correctly allocate and deallocate memory for all contained polyhedra, reflecting accurate deep copies of the objects.

Another critical aspect is ensuring that the scaling functions correctly modify the polyhedra's dimensions and their associated bounding boxes. Proper scaling ensures that the geometric representations are accurate after transformations; neglecting to scale the bounding boxes, which define spatial extents, can lead to incorrect rendering or spatial queries. The use of BoundingBox::scale or Polyhedron::scale functions ensures the geometric consistency of objects after scaling.

The testing suite evaluates several functions and behaviors of the Composite class, including default construction, adding polyhedra, cloning, reading input, scaling, and displaying data. Passing all tests indicates robust implementation aligning with object-oriented best practices, careful memory management, and correct geometric transformations. Failures point to potential issues such as shallow copying, memory leaks, or incorrect scaling logic that need revisiting and fixing.
