In OpenGL there are three transformations that the user needs to specify in order to complete specify the transformation of 3D points to 2D screen pixel coordinates. These are the Modelview, Projection and Viewport. Please specify which of these might need to be updated for each of the following situations. a. The object is rotated 30 degrees from its current position.
b. The program widens the field of view of the scene from a narrow angle to a wide angle.
c. The user interactively changes the window size. (Projection is one, what is the other?
d. Using Lookat to view an object from a specified position and orientation.
A. Projection
B. Modelview
C. Viewpoint

Read the code below. what will the computer print if the input for year_variable is 1700? if year_variable == 1776: print("your answer is correct. the declaration of independence was signed in “year_variable”.") elif year_variable < 1776: compute_variable = 1776 - year_variable. print("add “compute_variable“ years to your answer for the correct answer.") elif year_variable > 1776: compute_variable = year_variable - 1776 print("subtract “compute_variable” years from your answer for the correct answer.")

Design a class tictactoe that: holds the following information about the game: two-dimensional array (3 by 3), and winner. add additional variables as needed. includes the functions to perform the various operations on objects. for example, function to print the board, getting the move, checking if move is valid, determining if there is a winner after each move. add additional operations as needed. includes constructor(s). write the functions of the class, and write a program that uses the class. the program should declare an object of type tictactoe. the program will create the board and store it in the array. the program will allow two players to play the tic-tac-toe game. after every valid move update the array, check if there is a winner. if there is no winner and no tie, then print the board again to continue.
