Geometric modeling is a way of creating shapes on a computer. It is like playing with Lego but with shapes on a computer instead of physical pieces. You can think of it like art or designing something – you can take basic shapes and move them around to make something new. To start, you pick a shape you want to work with — like a cube, a circle, a triangle, etc. Then you can stretch and twist the shape to make something more interesting. You can also add more shapes, mix different colors, and make designs. When you’re done, you will have a nice looking model that you can show to others.
