### Some articles on polygons, polygon:

Boolean Operations On Polygons - Uses in Software
... Early algorithms for Boolean operations on polygons were based on the use of bitmaps ... Using bitmaps in modeling polygon shapes has many drawbacks ... be very large, since the resolution of polygons is proportional to the number of bits used to represent polygons ...
Modeler - Modeling Process
... However, polygons are planar and can only approximate curved surfaces using many polygons ... uses a dense model (often generated by Subdivision surfaces of a polygon control mesh) and stores new locations for the vertex positions through use of a ... as displacement but does not suffer from polygon stretching when there are not enough polygons in a region to achieve a deformation ...
Sahys Mod - Data Requirements - Polygonal Network
... permits a maximum of 240 internal and 120 external polygons with a minimum of 3 and a maximum of 6 sides each ... The subdivision of the area into polygons, based on nodal points with known coordinates, should be governed by the characteristics of the distribution of the cropping ... Nodal network relations are to be given indicating the neighboring polygon numbers of each node ...
Bicentric Polygon - Regular Polygons
... For all regular polygons, x=0 ... This center is also the center of the regular polygon ... For some regular polygons which can be constructed with compass and ruler, we have the following formulas for the relation between the common edge length a, the radius r of the incircle ...
Mesh Subdivision
... Mesh Subdivision is a technique used to add detail to a polygon mesh by breaking into smaller pieces the polygons in the mesh ... Because computers are limited in the number of polygons they can render per second, different techniques are often used to reduce the number of polygons visible ... The polygons (usually triangles) in the mesh are divided in a way that the ones closest to the viewpoint are much smaller, and the size of the polygons grows the farther they are from the viewpoint ...
