ECE 4122/6122 Lab 3: OpenGL with OBJ files and Multiple Objects
(100 pts)
Category: 3D Graphics
Due: Tuesday October 22th , 2023 by 11:59 PM
Objective:
To create a dynamic 3D graphics application using lighting, shading, model transformations, andkeyboard inputs.
Description:
You can use the code from tutorial09_Assimp to create a C++ application that loads in the obj files for
the 3D chess pieces and the chess board.Modify the keyboard inputs so that (5 points each)
- 1) ‘w’ key moves the camera radially closer to the origin.
- 2) ‘s’ key moves the camera radially farther from the origin.
- 3) ‘a’ key rotates the camera to the left maintaining the radial distance from the origin.
- 4) ‘d’ key rotates to camera to the right maintaining the radial distance from the origin.
- 5) The up arrow key radially rotates the camera up.
- 6) The down arrow radially rotates the camera down.
- 7) The ‘L’ key toggles the specular and diffuse components of the light on and off but leaves the
ambient component unchanged.
- 8) Pressing the escape key closes the window and exits the program
Points grading:
- 30 Points – loading obj files and displaying the chess pieces.
- 30 Points – rotating and placing the chess pieces in the correct location and orientation
- 40 Points – keyboard control described above
- 5 pts extra credit the textures are applied correctly to the chess pieces and chessboard.
- 5 pts extra credit make a short, narrated video of your program in action. (include it in the zip
file)Turn-In Instructions
Create a Lab3 folder at the same level as the other tutorialxx _xx folders and place your code and the attachedfolders containing the obj file information in that folder.Modify the top level CMakeLists.txt file to build代 写ECE 4122/6122 OpenGL with OBJ files and Multiple Objects your Lab3 application. You can make any needed changesto the files in the common folder to handle the keyboard input.Zip up the folders Lab3 and common into Lab3.zip and upload this zip file on the assignment sectionofCanvas. When the TAs replace the existing folders with yours and the code should compile and run correctly.You can also include a short, narrated video of your program in action.
Grading Rubric:
If a student’s program runs correctly and produces the desired output, the student has the potential to get a 100
on his or her homework; however, TA’s will look through your code for other elements needed to meet the lab
requirements. The table below shows typical deductions that could occur.
AUTOMATIC GRADING POINT DEDUCTIONS PER PROBLEM:
Camel Case: This naming convention has the first letter of the variable be lower case, and the first letter in each new wordbe capitalized (e.g. firstSecondThird).his applies for functions and member functions as well!
The main exception to this is class names, where the first letter should also be capitalized.
Variable and Function Names: Your variable and function names should be clear about what that variable or function represents. Do not useone letter variables, but use abbreviations when it is appropriate (for example: “imag" instead of“imaginary”). The more descriptive your variable and function names are, the more readable your code will
- This is the idea behind self-documenting code. File Headers:Every file should have the following header at the top
/*
Author: your nameClass: ECE4122 or ECE6122 (section)Last Date Modified: date
Description:What is the purpose of this file?
*/
Code Comments:
- Every function must have a comment section describing the purpose of the function, the input andoutput parameters, the return value (if any).
- Every class must have a comment section to describe the purpose of the class.
- Comments need to be placed inside of functions/loops to assist in the understanding of the flow ofthe code.
