What are projection techniques?

Imagine you're trying to draw a 3D toy box on a flat piece of paper, it's tricky because you can only see 2D at once! That’s where projection techniques come in, they help turn things that are 3D into something we can easily draw or look at in 2D.

Think about when you shine a light on your toys. The shadow they make on the wall is like a projection! It’s not the whole toy, just a flat version of it. That's exactly what projection techniques do, they take something that has depth (like a 3D shape) and turn it into a flat picture (2D), so we can understand or see it more easily.

Sometimes you want to draw a room on paper, but the room is around you. A projection technique helps you map that 3D space onto your 2D drawing, like how you might draw a house with a roof and windows, even though you’re looking at it from outside!
