Fez, a video game where one plays a character who can see beyond the two dimensions other characters can see, and must use this ability to solve platforming puzzles. Features "Dot", a tesseract who helps the player navigate the world and tells how to use abilities, fitting the theme of seeing beyond human perception of known dimensional space.
With index arrays, a mesh is represented by two separate arrays, one array holding the vertices, and another holding sets of three indices into that array which define a triangle. The graphics system processes the vertices first and renders the triangles afterwards, using the index sets working on the transformed data.
Shortest path (A, C, E, D, F), blue, between vertices A and F in the weighted directed graph. In graph theory, the shortest path problem is the problem of finding a path between two vertices (or nodes) in a graph such that the sum of the weights of its constituent edges is minimized.
Example of Carmack's stencil shadowing in Doom 3. Shadow volume is a technique used in 3D computer graphics to add shadows to a rendered scene. It was first proposed by Frank Crow in 1977 [1] as the geometry describing the 3D shape of the region occluded from a light source.
The most common example is the pentagram, which has the same vertices as a pentagon, but connects alternating vertices. For an n-sided star polygon, the Schläfli symbol is modified to indicate the density or "starriness" m of the polygon, as {n/m}. If m is 2, for example, then every second point is joined. If m is 3, then every third point is ...
As the Haus vom Nikolaus puzzle has two odd-degree vertices (orange), the trail must start at one and end at the other. A variant with four odd-degree vertices has no solution. If there are no odd-degree vertices, the trail can start anywhere and forms an Eulerian cycle. Loose ends are considered vertices of degree 1. The graph must also be ...

Each of the 12 vertices at the one-third mark of each edge creates 12 pentagonal faces and transforms the original 20 triangle faces into regular hexagons. [1] Therefore, the resulting polyhedron has 32 faces, 90 edges, and 60 vertices. [2] A Goldberg polyhedron is one whose faces are 12 pentagons and some multiple of 10 hexagons.
