What is the triangle fan?

The triangle fan is a collection of triangles grouped around the main peak and used in three -dimensional (3D) graphics to create computer models and eye. The triangle fan is considered primitive, such as a line or dot, because it is used to create complex shapes. Most polygons used to produce a polygon network are - or can be - divided into a fan, which makes it easier to control and manipulate polygon. In addition to checking, the biggest advantage is the use of this fan that the computer can process the shape faster and storage is much easier to maintain lines.

The triangle fan is suitably named because the shape looks like a fan. It begins with the main peak and all triangles are associated with this peak. If a triangle is attached to another triangle instead of the peak, then the shape is considered a strip of triangle.

in computer graphics, there are shapes known as primitives; It's not because shapes are stArena and not Myed already, but because they are able to build other shapes. While most primitives are very simple shapes such as a line or dot, the triangle fan is a bit more complicated than most of the primitives. This allows programmers to create shapes that would not otherwise be impossible - or at least difficult - to encode.

Polygon network structures are used in low -level structures, usually as a skeleton where high -level graphics can be placed or graphics that users can see. While the polygon net looks like mixing polygons, each polygon can be divided into a triangle fan. One point of polygon is used as the main peak and several triangles are formed around this peak. By using triangles instead of the whole polygon, programmers can easily handle the size and shape of the polygon. This makes the programming time a little longer, but allows very accurate measurements.

hlThe advantage of the triangle ventilator, instead of other shapes, is that the fan can load much faster. The computer must load fewer lines because the lines side by side are calculated as one line. For example, if there are two triangles against each other, the computer will have to draw six lines; However, the fan is combined lines and only four lines are drawn. Storage also improves because maintaining lines means that the computer has to spend less memory.
