Physically based rendering

Physically based rendering is like playing dress-up with dolls!

Think of a doll as a 3D object in a computer, like a box or a ball. When you dress up your doll, you can put clothes and accessories on it, right? Now imagine that you also get to choose things like the type of fabric or the color of the clothes, and how shiny or rough they look.

That's what physically based rendering is! It's a way of making 3D objects look more realistic by giving them textures and materials that behave like they would in real life.

For example, if you want to create a wooden block in a video game, you can use physically based rendering to make it look like it's made of real wood. You can choose the color and texture of the wood, and even make it look like it has little imperfections or knots.

The cool thing about physically based rendering is that it uses real-world properties of materials, like how they reflect light or how rough they are, to create realistic images. This makes games and movies look more lifelike and immersive, and it can help you feel like you're really inside the world of the game or movie.

So, just like how you can make your dolls look more realistic with different clothes and accessories, physically based rendering helps artists make their 3D objects look more lifelike with different textures and materials.
