  2. Vertex (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Vertex_(computer_graphics)

    Most attributes of a vertex represent vectors in the space to be rendered. These vectors are typically 1 (x), 2 (x, y), or 3 (x, y, z) dimensional and can include a fourth homogeneous coordinate (w). These values are given meaning by a material description. In real-time rendering these properties are used by a vertex shader or vertex pipeline.

  3. Wire-frame model - Wikipedia

    en.wikipedia.org/wiki/Wire-frame_model

    In 3D computer graphics, a wire-frame model (also spelled wireframe model) is a visual representation of a three-dimensional (3D) physical object. It is based on a polygon mesh or a volumetric mesh, created by specifying each edge of the physical object where two mathematically continuous smooth surfaces meet, or by connecting an object's constituent vertices using (straight) lines or curves.

  4. Morph target animation - Wikipedia

    en.wikipedia.org/wiki/Morph_target_animation

    Morph target animation, per-vertex animation, shape interpolation, shape keys, or blend shapes [1] is a method of 3D computer animation used together with techniques such as skeletal animation. In a morph target animation, a "deformed" version of a mesh is stored as a series of vertex positions.

  5. Wavefront .obj file - Wikipedia

    A valid vertex index matches the corresponding vertex elements of a previously defined vertex list. If an index is positive then it refers to the offset in that vertex list, starting at 1. If an index is negative then it relatively refers to the end of the vertex list, -1 referring to the last element. Each face can contain three or more vertices.

    Data managed by a graphics API, typically held in device memory, including vertex buffers, index buffers, texture maps and framebuffers Repeating texture A texture map applied with wrap-round UV coordinates extending between the 0–1 range (representing one unit of the image), exhibiting periodicity. Contrasts with clamped, mirrored modes or ...

  7. Tessellation (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Tessellation_(computer...

    In computer graphics, tessellation is the dividing of datasets of polygons (sometimes called vertex sets) presenting objects in a scene into suitable structures for rendering. Especially for real-time rendering, data is tessellated into triangles, for example in OpenGL 4.0 and Direct3D 11. [1] [2]

  8. Level of detail (computer graphics) - Wikipedia

    en.wikipedia.org/wiki/Level_of_detail_(computer...

    [1] [2] [3] LOD can be decreased as the model moves away from the viewer or according to other metrics such as object importance, viewpoint-relative speed or position. LOD techniques increase the efficiency of rendering by decreasing the workload on graphics pipeline stages, usually vertex transformations. The reduced visual quality of the ...

  9. Graphics pipeline - Wikipedia

    en.wikipedia.org/wiki/Graphics_pipeline

    In this case, a gain factor for the texture is calculated for each vertex based on the light sources and the material properties associated with the corresponding triangle. In the later rasterization step, the vertex values of a triangle are interpolated over its surface. A general lighting (ambient light) is applied to all surfaces.
