  2. Three-dimensional space - Wikipedia

    en.wikipedia.org/wiki/Three-dimensional_space

    In geometry, a three-dimensional space (3D space, 3-space or, rarely, tri-dimensional space) is a mathematical space in which three values (coordinates) are required to determine the position of a point. Most commonly, it is the three-dimensional Euclidean space, that is, the Euclidean space of dimension three, which models physical space.

  3. COGO - Wikipedia

    en.wikipedia.org/wiki/COGO

    COGO is a suite of programs used in civil engineering for modelling horizontal and vertical alignments and solving coordinate geometry problems. Cogo alignments are used as controls for the geometric design of roads , railways, and stream relocations or restorations.

  4. Analytic geometry - Wikipedia

    en.wikipedia.org/wiki/Analytic_geometry

    In mathematics, analytic geometry, also known as coordinate geometry or Cartesian geometry, is the study of geometry using a coordinate system. This contrasts with synthetic geometry . Analytic geometry is used in physics and engineering , and also in aviation , rocketry , space science , and spaceflight .

  5. Configuration space (physics) - Wikipedia

    en.wikipedia.org/wiki/Configuration_space_(physics)

    The set of coordinates that define the position of a reference point and the orientation of a coordinate frame attached to a rigid body in three-dimensional space form its configuration space, often denoted () where represents the coordinates of the origin of the frame attached to the body, and () represents the rotation matrices that define the orientation of this frame relative to a ground ...

  6. Solid modeling - Wikipedia

    en.wikipedia.org/wiki/Solid_modeling

    The geometry in solid modeling is fully described in 3‑D space; objects can be viewed from any angle. Solid modeling (or solid modelling) is a consistent set of principles for mathematical and computer modeling of three-dimensional shapes .

  7. Coordinate system - Wikipedia

    en.wikipedia.org/wiki/Coordinate_system

    In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.

  8. 3D modeling - Wikipedia

    en.wikipedia.org/wiki/3D_modeling

    The 3D model can be physically created using 3D printing devices that form 2D layers of the model with three-dimensional material, one layer at a time. Without a 3D model, a 3D print is not possible. 3D modeling software is a class of 3D computer graphics software used to produce 3D models. Individual programs of this class are called modeling ...

  9. Lode coordinates - Wikipedia

    en.wikipedia.org/wiki/Lode_Coordinates

    The radial coordinate is =. The octahedral profile is a 2D plot of ( r , θ ) {\displaystyle (r,\theta )} holding z {\displaystyle z} constant. Plotting the yield surface in the octahedral plane demonstrates the level of Lode angle dependence.
