# What istessellation

The article explains the use of triangles to represent 3D objects in surface and solid modeling. Triangles are formed from all surfaces to create a more realistic visualization but require more processing power. They can also be eliminated depending on their proximity to the camera. Tessellation is not used in 2D graphics, and artists must manually create depth and shading.

## What is Tessellation in 3D Graphics?

Tessellation, also known as tiling, refers to the technique used in 3D graphics to represent objects as a collection of triangles or other polygons in surface modeling and solid modeling. This method involves breaking up a surface or solid into smaller pieces, called triangles, to create a more realistic representation of the object.

Triangles are formed from all surfaces, curved and straight, either when they are being constructed or when they are being drawn in real-time. The visualization becomes more realistic but requires more processing the more triangles are used to represent a surface.

## Can Triangles Be Eliminated?

Triangular tessellation may be eliminated during the rendering process depending on the distance between the object and the camera. In some programs, various models with different numbers of triangles are created and the best one is utilized depending on the distance of the object from the camera.

Triangles are assigned X-Y-Z and RGB values at their vertices (end points), which are utilized to calculate light. By eliminating the number of triangles, the processing power required to render the 3D object can be reduced.

## Is Tessellation Only Used in 3D Graphics?

In 2D graphics, tessellation is not used. The creation of any simulation of depth and shading must be done by the artist using ordinary drawing tools, color fills, and gradients. Even if 2D graphics can be utilized to generate 3D objects, tessellation is not used.

In summary, tessellation is an essential technique in 3D graphics that involves breaking up objects into smaller triangles or polygons to create a more realistic representation of the object. While tessellation can increase processing power requirements, the number of triangles can be reduced by eliminating them during the rendering process. Tessellation is not used in 2D graphics, where depth and shading must be simulated by the artist.
