What is Geometry?

Geometry is a branch of mathematics that deals with the shapes and sizes of things. In the world of 3D visualization, geometry is used to create models of objects. This can be done by hand or using computer software.

Geometry is important in 3D visualization because it helps to create realistic images. If the geometry is not correct, the image will look wrong. For example, if a model of a house is created without taking into account the angles of the roof, the house will look strange.

There are many different types of geometry that can be used in 3D modeling. The most common type is polygonal geometry, which is made up of triangles. This type of geometry is often used because it is easy to create and edit. NURBS geometry is another type of geometry that is sometimes used. This type of geometry is more difficult to create, but it can produce smoother surfaces.
