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. Per-pixel lighting - Wikipedia

   en.wikipedia.org/wiki/Per-pixel_lighting

   In computer graphics, per-pixel lighting refers to any technique for lighting an image or scene that calculates illumination for each pixel on a rendered image. This is in contrast to other popular methods of lighting such as vertex lighting, which calculates illumination at each vertex of a 3D model and then interpolates the resulting values over the model's faces to calculate the final per ...

4. Vertex (geometry) - Wikipedia

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

   A vertex of an angle is the endpoint where two lines or rays come together. In geometry, a vertex (pl.: vertices or vertexes) is a point where two or more curves, lines, or edges meet or intersect. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices. [1] [2] [3]

5. Vertex (graph theory) - Wikipedia

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

   A graph with 6 vertices and 7 edges where the vertex number 6 on the far-left is a leaf vertex or a pendant vertex. In discrete mathematics, and more specifically in graph theory, a vertex (plural vertices) or node is the fundamental unit of which graphs are formed: an undirected graph consists of a set of vertices and a set of edges (unordered pairs of vertices), while a directed graph ...

6. Graph traversal - Wikipedia

   en.wikipedia.org/wiki/Graph_traversal

   This may be accomplished by associating each vertex of the graph with a "color" or "visitation" state during the traversal, which is then checked and updated as the algorithm visits each vertex. If the vertex has already been visited, it is ignored and the path is pursued no further; otherwise, the algorithm checks/updates the vertex and ...

7. Vertex normal - Wikipedia

   en.wikipedia.org/wiki/Vertex_normal

   Vertex normals of a dodecahedral mesh. In the geometry of computer graphics, a vertex normal at a vertex of a polyhedron is a directional vector associated with a vertex, intended as a replacement to the true geometric normal of the surface. Commonly, it is computed as the normalized average of the surface normals of the faces that contain that ...
