Overview

This week you will be continuing to work on the 3D scene you already

began to build, based on a 2D image you selected. Now it is time to

incorporate input devices and camera movement so you will be able to

traverse your scene more easily.

Prompt

You will complete your work in Visual Studio, being sure to work from

the project file you already created in a previous milestone. This file

already has the libraries set up correctly and contains the 3D object

you built, which will be necessary for you to add to this week.

Specifically, you must address the following rubric criteria:

• 
  Create a 3D plane to situate a 3D scene. This will
  
  serve as the base for the rest of the objects in your world. Depending
  
  on your 2D 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 will understand the scope of the world your camera
  
  will be traversing. A plane is also a relatively simple shape so it will
  
  be a good place to start when managing the placement of different
  
  objects in your scene. Remember, you will need to take into account
  
  where the plane is located in relation to the 3D object you developed
  
  during a previous milestone (which used multiple 3D shapes).

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

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

• 
  Create perspective and orthographic displays of a 3D scene.
  
  Use the tap of a keyboard key to allow a user to change the view of the
  
  scene between orthographic (2D) and perspective (3D) views at will.
  
  (Hint: check the glViewport and the glOrtho functions.) For consistency,
  
  please use the letter “P” keyboard key. To accomplish this work, you
  
  will be switching the function call to retrieve either the perspective
  
  or orthographic projection matrix. Note that you will be keeping the
  
  camera in the same orientation that you already developed.

• 
  Create code that follows a logical flow without syntax errors.
  
  The code you create has to be executable and all the code that is
  
  included needs to be reached by the execution. Note that not everything
  
  should be written in a single function and 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. Commenting best
  
  practices should be in place to ensure the source code is briefly and
  
  clearly explained using descriptive comments.

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. Checking for the EXE can

be used as a quick reference on the functionality of your code before

you submit.
