Recommended Viva Explanation

If teacher asks:
“How does animation work?”

Answer:

Animation is created using glutTimerFunc().
It repeatedly updates variables like moon position and logo rotation angle, then redraws the scene continuously.

---

If teacher asks:
“How is Batman drawn?”

Answer:

Batman is created using basic OpenGL primitives such as polygons, triangles, and circles.

---

If teacher asks:
“How does scene switching work?”

Answer:

A global variable called scene stores the current scene number. Keyboard input changes the value, and the display function draws different scenes accordingly.

Pi Day: Where Math Meets a Slice of Fun

Every year on March 14 (3/14), all the math lovers around the world celebrate Pi Day —as a tribute to the mathematical constant π (pi). The Value of Pi is 3.14. upto two decimal place. As these may be slipt to 3 and 14 represeting 3 as march month and 14 as date, hence PI DAY. This quirky holiday blends geeky fun with delicious pies, making math feel less intimidating and more indulgent.

Also the Value of Pi is long ending with each mathematician has cacluate to some extent of decimal places. The Pi represents the ratio of a circle’s circumference to its diameter and appears in countless formulas, theorem, thesis etc and used in various feilds including science, engineering, and technology. PI being an infinite and non-repeating number, it has become one of the most famous constants in mathematics.

When it statrtd PI DAY?

Today is Pi Day, celebrated on March 14 (or 3.14) to honor the mathematical constant π. 

Interestingly, Pi Day began in 1988 at the Exploratorium in San Francisco, where physicist Larry Shaw organized the first celebration. Over time, the tradition spread worldwide and even gained official recognition in the United States in 2009.

The Story of Origin: 1988 At the San Francisco Exploratorium, Pi Day was first officially observed. It was created by Larry Shaw, a physicist known as the "Prince of Pi." Shaw selected March 14 (3/14) as the date because it corresponds to the first three digits of the mathematical constant: 3.14. The Ritual: Shaw and his employees marched around one of the museum's circular areas as part of the first celebration, after which they ate a lot of fruit pies.The Logistics: Shaw discovered that "pi" and "pie" are homophones in addition to pies are—conveniently—circular in a flash of insight (or maybe just hunger).The Celebration's Development What was once a specialized staff party swiftly became a worldwide sensation.

Today, enthusiasts recite its endless digits, bake π-themed pies, and share memes poking fun at its irrational nature. In 2026, social media buzzes with crypto twists and cat-in-chef-hat antics, turning classrooms into pie parties.

One of the reasons Pi Day is so popular is the endless supply of math jokes and memes. After all, when a mathematical constant sounds exactly like a dessert, the internet can’t resist. You’ll often see jokes like: “It’s okay, Pi Day is all about the pie!”—a reminder that sometimes learning math can be both educational and delicious.

So whether you’re a mathematician, a student, or just someone who enjoys dessert, Pi Day is a perfect reminder that math can be fun, creative, and surprisingly tasty.

Google PI Day Doodle

Google has dedicate 14/03/2026 PI Day with a good mathematical Doodle as given - 

Google created a unique interactive Doodle in celebration of the ancient Greek mathematician Archimedes and his groundbreaking technique for determining the limits of pi in commemoration of Pi Day in 2026.

And remember: if anyone asks why you’re eating pie on March 14, just say it’s for educational purposes. 😄

Why not join in? Grab a slice of apple pie, ponder infinity, and remember: even Einstein would approve. Pi reminds us circles are endless—and so is the joy in a good pun. Happy Pi Day! (198 words) PI Day Video for you -https://www.youtube.com/shorts/ZWlDDm_R_HQ
