To create a dynamic 3D graphics application using lighting, shading, model transformations, and keyboard inputs.
Description:
Using the code from tutorial09_Assimp create an application that loads in the suzanne.obj file and creates 4 instances of the head object. Place (rotate) each of the heads so that it faces away from the origin along the +x-axis, -x-axis, +y-axis, and -yaxis. Translate the heads so that the ears of each head just barely touch and the chin of all the heads just touches the z = 0 plane. Place a green rectangle on the z = 0 plane that is sized to just extend past the front of all the heads.
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 file and displaying the fours heads and the green z = 0 rectangle
• 30 Points – rotating and placing the heads in the correct location and orientation
• 40 Points – keyboard control
• 5 pts extra credit – place a texture (of your choice) on the z=0 plane rectangle. Make sure to include the bmp file in your submission.
• 5 pts extra credit make a short, narrated video of your program in action. (include it in the zip
file)Turn-In InstructionsMake your required changes to the file tutorial09_several_objects.cpp and controls.cpp.Grading Rubric:AUTOMATIC GRADING POINT DEDUCTIONS PER PROBLEM:
Element Percentage Deduction Details
Does Not Compile 40% Code does not compile on PACE-ICE!
Does Not Match Output Up to 90% The code compiles but does not produce correct outputs.
Clear Self-Documenting Coding Styles Up to 25% This can include incorrect indentation, using unclear variable names, unclear/missing comments, or compiling with warnings. (See Appendix A)LATE POLICY
Element Percentage Deduction DetailsAppendix A: Coding Standards
Indentation:
When using if/for/while statements, make sure you indent 4 spaces for the content inside those. Also make sure that you use spaces to make the code more readable. For example:
for (int i; i < 10; i++)
{ j = j + i;
}If you have nested statements, you should use multiple indentions. Each { should be on its own line (like the for loop) If you have else or else if statements after your if statement, they should be on their own line.
for (int i; i < 10; i++)
{
if (i < 5) { counter++; k -= i; } else
{ k +=1; } j += i;
}Camel Case:
This naming convention has the first letter of the variable be lower case, and the first letter in each new word be capitalized (e.g. firstSecondThird).
This 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 use one 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 be. This is the idea behind self-documenting code.File Headers:
Every file should have the following header at the top
/*
Author: your name
Class: ECE4122 or ECE6122 (section)Description:What is the purpose of this file?*/Code Comments:1. Every function must have a comment section describing the purpose of the function, the input and output parameters, the return value (if any).
2. Every class must have a comment section to describe the purpose of the class.
3. Comments need to be placed inside of functions/loops to assist in the understanding of the flow of the code.
