A vertex buffer object (VBO) is an OpenGL feature that provides methods for uploading vertex data (position, normal vector, color, etc.) to the video device for non-immediate-mode rendering. VBOs offer substantial performance gains over immediate mode rendering primarily because the data reside in video device memory rather than system memory ...
Vertex buffer A rendering resource managed by a rendering API holding vertex data. May be connected by primitive indices to assemble rendering primitives such as triangle strips. Also known as a Vertex buffer object in OpenGL. Vertex cache A specialised read-only cache in a graphics processing unit for buffering indexed vertex buffer reads ...

For example, if is non-basic and its coefficient in is positive, then increasing it above 0 may make larger. If it is possible to do so without violating other constraints, then the increased variable becomes basic (it "enters the basis"), while some basic variable is decreased to 0 to keep the equality constraints and thus becomes non-basic ...
A graceful labeling; vertex labels are in black and edge labels in red. A graph is known as graceful if its vertices are labeled from 0 to | E |, the size of the graph, and if this vertex labeling induces an edge labeling from 1 to | E |. For any edge e, the label of e is the positive difference between the labels of the two vertices incident ...
The only way vertex order can change in two dimensions is by reflection. Reflection is an example of involutory function (with respect to vertex order), therefore an even number of reflections will leave the triangle facing the same side, as if no reflections were applied at all. An odd number of reflections will leave the triangle facing the ...
Because A is symmetric, the spectral theorem implies that A has n real-valued eigenvalues λ 1 ≥ λ 2 ≥ … ≥ λ n. It is known that all these eigenvalues are in [−d, d] and more specifically, it is known that λ n = −d if and only if G is bipartite. More formally, we refer to an n-vertex, d-regular graph with
The discharging method is a technique used to prove lemmas in structural graph theory. [1] Discharging is most well known for its central role in the proof of the four color theorem . The discharging method is used to prove that every graph in a certain class contains some subgraph from a specified list.
