Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the inventor?Ken Perlin
2. What is the year of introduction?1982
3. What is Perlin noise and why is it used in computer graphics?Perlin noise is a special pattern that looks natural, like mountains or clouds. It helps computers make pictures that feel real instead of flat and artificial.
4. How does Perlin noise make mountains and clouds look smooth?It uses a grid where each corner has a random direction. The algorithm blends these directions smoothly so the picture changes gradually, giving a flowing look.

Gradient Noise: A type of procedural noise based on interpolating random gradient vectors at grid points.
Procedural Generation: The creation of data algorithmically, enabling complex content generation from simple rules.
Interpolation: Estimating values between known data points, crucial for smooth transitions in Perlin noise.
Fractional Brownian Motion (fBm): A technique often layered with Perlin noise to create fractal-like details and complexity.
