The vector projection (also known as the vector component or vector resolution) of a vector a on (or onto) a nonzero vector b is the orthogonal projection of a onto a straight line parallel to b. The projection of a onto b is often written as proj b a {\displaystyle \operatorname {proj} _{\mathbf {b} }\mathbf {a} } or a ∥ b .
An earlier version of the Box2D engine, now known as Box2D Lite, was released primarily for educational purposes, based on a series of yearly Game Developers Conference presentations that Erin Catto has given. Box2D Lite uses many of the same algorithms as Box2D, but has a smaller feature set.
Live2D is an animation technique used to animate static images—usually anime-style characters—that involves separating an image into parts and animating each part accordingly, without the need of frame-by-frame animation or a 3D model.
A vector-based graphical user interface is a mostly conceptual type of graphical user interface where elements are drawn using vector information instead of raster information. An example of a vector-based window, found in a privately funded vector-based graphical user interface research project. 2D GUI. All window decorations and elements ...
It is an ill-posed problem as the motion happens in three dimensions (3D) but the images are a projection of the 3D scene onto a 2D plane. The motion vectors may relate to the whole image ( global motion estimation ) or specific parts, such as rectangular blocks, arbitrary shaped patches or even per pixel .
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 ...
2.5D (basic pronunciation two-and-a-half dimensional) perspective refers to gameplay or movement in a video game or virtual reality environment that is restricted to a two-dimensional (2D) plane with little to no access to a third dimension in a space that otherwise appears to be three-dimensional and is often simulated and rendered in a 3D digital environment.
In this method, the user creates a 2D shape which traces the outline of an object from a photograph or a drawing. [3] The user then uses a second image of the subject from a different angle and extrudes the 2D shape into 3D, again following the shape’s outline. This method is especially common for creating faces and heads.
