EDGE TESSELLATION Meaning and
Definition
-
Edge tessellation is a term commonly used in the field of computer graphics and computational geometry to describe the process of dividing a surface or shape into smaller, interconnected polygons along its edge. This technique is employed to construct complex and detailed 3D models by breaking down the surface or shape into a tessellated grid, which allows for smoother rendering and manipulation.
The process of edge tessellation involves dividing the original surface or shape into smaller segments, usually through the addition of new vertices and edges along the boundary. By segmenting the surface, a more refined approximation of the shape can be achieved, leading to enhanced visual quality when rendered or animated.
Edge tessellation is particularly useful in rendering highly detailed objects and characters in computer-generated imagery (CGI) and video games. It enables the representation of intricate surface features, such as fine textures, wrinkles, or creases, by breaking them down into smaller polygons. This technique provides a greater level of realism and detail to the rendered object.
In addition to rendering applications, edge tessellation is also utilized in computational geometry algorithms for shape analysis, collision detection, and mesh generation. It facilitates efficient storage and processing of geometric data by converting complex surfaces into simpler polygon meshes with well-defined topological relationships.
Overall, edge tessellation is a fundamental technique in computer graphics and computational geometry that allows for the representation and manipulation of detailed 3D models by breaking down their surfaces into interconnected polygons along their edges.
Etymology of EDGE TESSELLATION
The etymology of the term "edge tessellation" can be broken down as follows:
1. Edge: The word "edge" comes from the Old English word "ecg", which means "a cutting side of a blade or tool". It has evolved to refer to the boundary or perimeter of an object.
2. Tessellation: The word "tessellation" is derived from the Latin word "tessella", which means "a small square tile". It refers to the process of creating a pattern by fitting together identical shapes without any gaps or overlaps.
3. Edge Tessellation: The term "edge tessellation" combines the two words to describe a specific type of tessellation. Here, "edge" indicates that the tessellation is created by using the edges or boundaries of the shapes, rather than the interiors. It suggests that the shapes are fitted together along their edges to form a larger pattern without any gaps or overlaps.
