Questions & Answers

Q: Why is math important in programming?

Math is important in programming because it enables programmers to solve complex problems, handle algorithms, and work with concepts like graphics, machine learning, and cryptography. It allows for more efficient and precise coding.

Q: How is the donut shape created in the program?

The donut shape is created using a solid of revolution concept, where a circle rotates around the y-axis. The formula to create the circle and the rotation matrix to rotate it around the y-axis are combined to obtain the coordinates for each point on the donut.

Q: How is the 3D donut rotated to make it look dynamic?

The donut is rotated around the x and z axes by multiplying its coordinates with two rotation matrices. This rotation gives the appearance of the donut flying and moving in a visually appealing manner.

Q: How is shading applied to the donut?

To shade the donut, the dot product of the surface normal and the direction of light is calculated. The dot product determines how light or dark a point on the donut appears. The resulting value is then mapped to a range of characters from darkest to brightest for visualization.
