A 3-D model is a mathematical representation of any three-dimensional object; a model is not technically a graphic until it is displayed. A model can be displayed visually as a two-dimensional image through a process called 3-D rendering, or it can be used in non-graphical computer simulations and calculations.
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 that are further away ...
Rendering of constructive solid geometry is particularly simple when ray tracing.Ray tracers intersect a ray with both primitives that are being operated on, apply the operator to the intersection intervals along the 1D ray, and then take the point closest to the camera along the ray as being the result.
The term 3D printing or three-dimensional printing is a form of additive manufacturing technology where a three-dimensional object is created from successive layers of material. [18] Objects can be created without the need for complex expensive molds or assembly with multiple parts. 3D printing allows ideas to be prototyped and tested without ...
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 ...
A computer-generated image featuring a house at sunset, made in Blender. Modern architects use services from computer graphic firms to create 3-dimensional models for both customers and builders. These computer generated models can be more accurate than traditional drawings.
Computer-generated image created by Gilles Tran. Following is a list of notable 3D modeling software, computer programs used for developing a mathematical representation of any Three Dimensional surface of objects, also called 3D modeling.
Computer-generated animation is an umbrella term for three-dimensional animation, and 2D computer animation. These also include subcategories like asset driven , hybrid, and digital drawn animation. Creators animate using code or software instead of pencil-to-paper drawings.
