Learning Goal: I’m working on a c++ project and need the explanation and answer to help me learn.

Overview

In this course, many assignments are paired with tutorials to help you to learn OpenGL and build the computer graphics skills that you will need to successfully complete your coding and design work.

In this assignment, you will create commented code for 2D shapes in modern OpenGL.

If you encounter any challenges while completing this assignment, be sure to post your questions or issues to the General Questions discussion. It is essential to ask for help when you need it and successfully complete each activity, as the course will continue to build on earlier learning as your skills progress.

Prompt

Before you begin, be sure to review the module resources for this weeks topics. Then, if you have not done so already, navigate to the in GitHub. From there, download the ZIP file containing all of the items within this folder, including assignment tutorials for Module Two through Module Six. There are two essential parts to these tutorials: the markdown (MD) files that walk you through how to work with different OpenGL capabilities, and the solution (SLN) file that contains all the code for each section of the tutorials. On your own machine, open the solution (SLN) file in Visual Studio and navigate to the Module Four tutorial sections in the Solution Explorer. While you may open the markdown (MD) file using an external text-based program, we recommend you instead follow along with the in GitHub so it is easier to review the different sections, code, and supporting images. Going through all the sections in the tutorial and attempting the embedded exercises will help you practice the skills you will need to demonstrate in this assignment.

Once you understand the content in the tutorial, you will begin this assignment by opening a new Visual Studio project that has all the libraries set up correctly (which you learned how to do in a previous module). The goal of this assignment is to write commented modern OpenGL code that allows for panning, zooming, and orbiting a pyramid. Use the keyboard, mouse, and movement combinations below:

  • WASD keys: These keys should be used to control the forward, backward, left, and right motion.
  • QE keys: These keys should be used to control the upward and downward movement.
  • Mouse cursor: This should be used to change the orientation of the camera so it can look up and down or right and left.
  • Mouse scroll: This should be used to adjust the speed of the movement, or the speed the camera travels around the scene.

Specifically, you must address the following rubric criteria:

  • Create code to address the required functionality. The work you complete in OpenGL must meet the required functionality and visual representation that are outlined for this particular topic. Achieving this result may require multiple attempts or the application of programming strategies, but that is okay! Working in iterations is an important part of any coding project. You may also wish to refer back to relevant sections of this weeks tutorial for further guidance or review.
  • Apply logic and proper syntax to code. Source code should be free of logical or syntax errors that prevent the application from running as expected. You will be given credit for code that is well on its way to meeting specifications or solving the problem.
  • Apply commenting and formatting standards to facilitate understanding of the code. All code should be well commented. This is a practiced art that requires clarity and concision. Your comments should explain the purpose of lines or sections of the code and may also include the method you used to achieve a specific task in the code. Be sure to document any sections of code that are producing errors or incorrect results. Also, all code should be organized to meet formatting standards.

Guidelines for Submission

Submit a completed ZIP folder with all of your code, which may include one or multiple CPP files along with Visual Studio project files. Also make sure the ZIP folder includes an EXE file, because without this your code will not be able to run.

I have tried to attach a project that is mostly already complete but it’s too big. I can link it from ufile.io if that is okay. I need to add functionality to the Q and E keys, along with mouse and scroll wheel functionality. The program is mostly complete but I can’t figure out how to get the Q and E keys working. I know they’re reliant on the ‘camera.h’ file, but I don’t know how to code their functionality in ‘camera.h’. There are also an identifier ‘Camera’ that I don’t know how to point to. Also, ‘glm::perspective‘ on line 323 isn’t working, I’m unsure why. Above, under “Prompt”, you’ll find a link to a GitHub repository that should have everything needed as far as header files. When I run it from that project everything works (except the Q and E key functionality). Also, when you run the program it shows several cubes that when zoomed out form a triangle shape but the instructions say to use an actual pyramid. If you can replace the cubes with just one 3D triangle, that would be great.
