  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. Cube mapping - Wikipedia

    en.wikipedia.org/wiki/Cube_mapping

    Cube mapping was first proposed in 1986 by Ned Greene in his paper “Environment Mapping and Other Applications of World Projections”, [3] ten years after environment mapping was first put forward by Jim Blinn and Martin Newell. However, hardware limitations on the ability to access six texture images simultaneously made it infeasible to ...

  4. 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.

  5. UV mapping - Wikipedia

    en.wikipedia.org/wiki/UV_mapping

    UV mapping is the 3D modeling process of projecting a 3D model's surface to a 2D image for texture mapping. The letters "U" and "V" denote the axes of the 2D texture because "X", "Y", and "Z" are already used to denote the axes of the 3D object in model space, while "W" (in addition to XYZ) is used in calculating quaternion rotations, a common ...

  6. 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 ...

  7. 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 .

  8. Projective texture mapping - Wikipedia

    en.wikipedia.org/wiki/Projective_texture_mapping

    Projective texture mapping is a method of texture mapping that allows a textured image to be projected onto a scene as if by a slide projector. Projective texture mapping is useful in a variety of lighting techniques and it is the starting point for shadow mapping .

  9. 360 video projection - Wikipedia

    en.wikipedia.org/wiki/360_video_projection

    This projection was then split horizontally in two streams of 4032x1344 and encoded, which could be decoded by regular UHD decoders. Mainstream video tools have not yet added support for EAC formats, such as GoPro's .360. A custom fork of FFmpeg [6] [7] and a tool called max2sphere [8] however do enable .360 processing.
