Description
Purpose: This is a development of assignment 2. It works in a very similar way but with the addition of two new classes SystemMemoryImage and GPUMemoryImage, that are derived from the abstract base class Image. Like assignment 2, it is a console application that holds the GraphicElements of a RasterGraphic application (there is no actual graphics in the assignment) in a forward_list class template of unspecified length in dynamic memory. Each GraphicElement now holds a vector of Image* pointers that are the addresses of the Image objects that are actually SystemMemoryImage or GPUMemoryImage objects. Polymorphic inheritance ensures that any Image* in the vector will call the correct overridden polymorphic function (Buffersize() in this case) for the actual object it points to. Also a SystemMemoryImage object uses more memory than a GPUMemoryImage object because they reside in different memory locations in the computer: in system memory or GPU local memory respectively. A GPUMemoryImage object also has a shader file that is a small fragment of code that executes for each pixel in the Image buffer. Therefore you will use an expression like Images[i]->BufferSize() to cause one of the Image* in the GraphicElement vector to calculate the buffer size of the SystemMemoryImage or GPUMemoryImage it points to without needing to identify what type of Image it really is. The polymorphic function that actually executes is the correct one for the object type, selected through the virtual function table of the object. In places where you need to identify the type of Image (SystemMemoryImage or GPUMemoryImage), but not where polymorphism is appropriate, use dynamic_cast<>. To focus on the polymorphic aspects of this final assignment, some of the overloaded operators used in Assignment 2 have been removed. Part of the code is shown on the next page; it is also on Brightspace in a text file that you can copy and paste. Do not change this code. You MUST use this code without modification (not a single character changed): no code added or removed, no new global variables or functions, no new classes, no macros, no defines and no statics. Your task is to implement, using C++, only the RasterGraphic, GraphicElement and Image class member functions and the global insertion operators and not add any new ones. Everything you write and submit is in the files: RasterGraphic.cpp, GraphicElement.cpp and Image.cpp. The RasterGraphic is a series of GraphicElements held in a forward_list. Each GraphicElement holds its list of Image* in a vector. There are now two types of Image, as detailed above, both subclasses of the abstract base class Image. Each Image object contains its Image time which is set by the user. You can: Add a new GraphicElement to the RasterGraphic at a position in the forward list selected by the user Delete the first GraphicElement in the RasterGraphic Run the RasterGraphic to show the list of Image details of each GraphicElement one after another at the Image intervals specified by the user when the Image was entered – note that the output counts up the seconds using a timer as was done in assignment 1 onwards. Quit CST 8219 – F18 – Assignment #3 2 An example of the output of the running application is given at the end. Yours must work identically and produce identical output. Note the following: dynamic memory management is done with new and delete input and output is done with cin and cout there is no unused dynamic memory at any time string objects are used in the RasterGraphic and GraphicElement classes to hold strings (a char array is still used in the Image class) Release of dynamically allocated memory is done in destructors so there is no resource leak (or you lose 30%). See the Marking Sheet for how you can lose marks, but you will lose at least 60% if: 1. you change the supplied code in any way at all (not a single character) – no code added or removed, no macros, no defines, no statics and no additional classes, global functions or variables, 2. it fails to build in Visual Studio 2015, 3. It crashes in normal operation, 4. it doesn’t produce the example output. Part of the code is shown on the next page. You MUST use this code without modification. Your task is to implement the RasterGraphic, GraphicElement and Image class member functions in their .cpp files. What to Submit : Use Blackboard to submit this assignment as a plain zip file (not RAR or 7-Zip or 9 Zip) containing only RasterGraphic.cpp, GraphicElement.cpp and Image.cpp. The name of the zipped folder must contain your name as a prefix so that I can identify it, for example using my name the file would be tyleraAss3CST8219.zip. It is also vital that you include the Cover Information (as specified in the Submission Standard) as a file header in your source file so the file can be identified as yours. Use comment lines in the file to include the header. Before you submit the code, check that it builds and executes in Visual Studio 2015 as you expect – if it doesn’t build for me, for whatever reason, you get a deduction of at least 60%. make sure you have submitted the correct file – if I cannot build it because the file is wrong or missing from the zip, even if it’s an honest mistake, you get 0. It cannot be late – no time at the semester end. Don’t send me files as an email attachment – they will get 0. Supplied code (also in a text file you can copy and paste on BlackBoard).
