Interactive geometry software (IGS) or dynamic geometry environments (DGEs) are computer programs which allow one to create and then manipulate geometric constructions, primarily in plane geometry. In most IGS, one starts construction by putting a few points and using them to define new objects such as lines , circles or other points.
Three spin-off games accompany the main series: Geometry Dash Meltdown, Geometry Dash World and Geometry Dash SubZero. Geometry Dash Lite is a free version of the main game that removes certain levels and icons, the level editor, and many online features. Both the spinoff games and Geometry Dash Lite contain advertisements.
JTS implements the geometry model and API defined in the OpenGIS Consortium Simple Features Specification for SQL. JTS defines a standards-compliant geometry system for building spatial applications; examples include viewers, spatial query processors, and tools for performing data validation, cleaning and integration.
Shorter codes are reserved for densely populated areas. The last idea, especially, yields very good results. For example, although every location within the Netherlands can be identified by a 6-letter mapcode, half of the Dutch population can be found in about 40 cities and densely populated areas that together comprise less than 6,000 square ...
A texture map (left). The corresponding normal map in tangent space (center). The normal map applied to a sphere in object space (right). Normal map reuse is made possible by encoding maps in tangent space. The tangent space is a vector space, which is tangent to the model's surface. The coordinate system varies smoothly (based on the ...
GML defines features distinct from geometry objects. A feature is an application object that represents a physical entity, e.g. a building, a river, or a person. A feature may or may not have geometric aspects. A geometry object defines a location or region instead of a physical entity, and hence is different from a feature.
Displacement mapping is an alternative computer graphics technique in contrast to bump, normal, and parallax mapping, using a texture or height map to cause an effect where the actual geometric position of points over the textured surface are displaced, often along the local surface normal, according to the value the texture function evaluates to at each point on the surface.

The Denso MapCode system divided Japan into 1162 zones, each zone into 900 blocks, and each block into 900 areas. A Denso MapCode number consists of the zone number (up to 4 digits), the block number (always 3 digits) and the area number (always 3 digits), a numeric code of up to 10 digits.
