  2. Projection mapping - Wikipedia

    en.wikipedia.org/wiki/Projection_mapping

    Projection mapping, similar to video mapping and spatial augmented reality, is a projection technique [1] [2] used to turn objects, often irregularly shaped, into display surfaces for video projection. The objects may be complex industrial landscapes, such as buildings, small indoor objects, or theatrical stages.

  3. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane.

    en.wikipedia.org/wiki/List_of_map_projections

    Arithmetic mean of the equirectangular projection and the Aitoff projection. Standard world projection for the NGS since 1998. 1904 Van der Grinten: Other Compromise Alphons J. van der Grinten: Boundary is a circle. All parallels and meridians are circular arcs. Usually clipped near 80°N/S. Standard world projection of the NGS in 1922–1988 ...

  5. 3D rendering - Wikipedia

    en.wikipedia.org/wiki/3D_rendering

    Perspective projection. The shaded three-dimensional objects must be flattened so that the display device - namely a monitor - can display it in only two dimensions, this process is called 3D projection. This is done using projection and, for most applications, perspective projection. The basic idea behind perspective projection is that objects ...

  6. Planar projection - Wikipedia

    en.wikipedia.org/wiki/Planar_projection

    Planar projections are the subset of 3D graphical projections constructed by linearly mapping points in three-dimensional space to points on a two-dimensional projection plane. The projected point on the plane is chosen such that it is collinear with the corresponding three-dimensional point and the centre of projection .

  7. Shadow mapping - Wikipedia

    en.wikipedia.org/wiki/Shadow_mapping

    Shadow mapping or shadowing projection is a process by which shadows are added to 3D computer graphics. This concept was introduced by Lance Williams in 1978, in a paper entitled "Casting curved shadows on curved surfaces."

  8. Texture mapping - Wikipedia

    en.wikipedia.org/wiki/Texture_mapping

    A texture map [5] [6] is an image applied (mapped) to the surface of a shape or polygon. [7] This may be a bitmap image or a procedural texture.They may be stored in common image file formats, referenced by 3D model formats or material definitions, and assembled into resource bundles.

  9. Projection - Wikipedia

    en.wikipedia.org/wiki/Projection

    Projection (set theory), one of two closely related types of functions or operations in set theory; Projection (measure theory), use of a projection map in measure theory; 3D projection, any method of mapping three-dimensional points to a two-dimensional plane; Vector projection, orthogonal projection of a vector onto a straight line
