What is Non-planar?

Non-planar is a term used to describe three-dimensional objects that are not flat. While most objects in the real world are non-planar, many 2D drawings and illustrations are created as if they were planar. This can make it difficult to understand how to create or interpret non-planar geometry.

In 3D visualization, non-planar objects are often represented using wireframes or meshes. These representations can be helpful in understanding the shape of an object, but they can also be distracting if you’re trying to focus on other features. By contrast, some rendering techniques (such as ray tracing) can produce realistic images of non-planar objects without Wireframes and meshes can be used together to create more realistic images.
