CS $330$ Milestone Three Guidelines and Rubric

Overview

This week, you will be continuing to work on your $3$D scene. Now, it is time to incorporate input devices and camera movement so you can navigate your scene more easily.

Scenario

Recall from reviewing the Final Project Guidelines and Rubric that you work as a C$++$ and OpenGL $3$D graphics developer for Triangle and Cube Studios. You have been tasked with writing code in OpenGL to create objects, add texture, apply light, render, and control virtual environments relative to a virtual camera. Review the Final Project Guidelines and Rubric to refresh yourself on the full scenario.

Directions

You will complete your work in Visual Studio. Be sure to work from the project file that was pre$-$created for the milestones and final project. As a reminder, the project is located in the CS$330$Content$/$Projects$/7-1\_$FinalProjectMilestones folder. This project already has the libraries set up correctly and contains the $3$D object you built. You will add to the project this week.

Specifically, you must address the following rubric criteria:

Create a $3$D plane to situate a $3$D scene. The $3$D plane will serve as the base for the rest of the objects in your world. Depending on your $2$D image, this plane may be used to represent a desk, the ground, a table, or something else entirely. It will be important to work on this first so you understand the scope of the world your camera will be passing through. A plane is also a relatively simple shape, so it will be a good place to start when placing different objects in your scene. Remember, you need to consider where the plane is located in relation to the $3$D object you developed previously.

Apply horizontal, vertical, and depth camera navigation around a $3$D scene. It is recommended that you use the following keyboard controls to manipulate the basic camera movement:

WASD keys should be used to control the forward, backward, left, and right motion.

QE keys should be used to control the upward and downward movement.

Apply nuanced camera controls to a $3$D scene. It is recommended that you use the following mouse controls to allow a user more specific input options for how they view the $3$D scene:

Mouse cursor should be used to change the orientation of the camera so it can look up and down or right and left.

Mouse scroll should be used to adjust the speed of the movement or the speed at which the camera travels around the scene.

Create perspective and orthographic displays of a $3$D scene. Use the tap of a keyboard key to allow a user to change the view of the scene between orthographic $(2$D$)$ and perspective $(3$D$)$ views at will. Hint: Check the glViewport and the glOrtho functions. For consistency, use the letter P keyboard key for perspective view and the letter O key for orthographic view. To do this work, switch the function call to retrieve either the perspective or orthographic projection matrix. Because of the nature of the projection methods, the camera settings will be different between perspective and orthographic projection. For orthographic projection, the camera will look directly at the $3$D object. The bottom plane should not be visible if the orthographic projection is correct.

Create code that follows a logical flow without syntax errors. The code you create has to be executable. The code that is included needs to be reached by the execution. You don$$t have to include everything in a single function. Your work should be well modularized.

Apply coding best practices in your creations. Pay particular attention to the way you format and comment your code. Program code should be easy to read and follow industry$-$standard code formatting practices, such as indentation and spacing. The source code should be brief and clear. Use descriptive comments.
