Computer graphics requires more math than is covered here. The purpose of these notes is to expand on the mathematical appendix included with most graphics books not to teach the mathematical material in the main text of those books.A zero vector denoted is a vector of length 0 and thus has all components equal to zero. Since vectors remain unchanged under translation it is often convenient to consider the tail as located at the origin when for example defining vector addition and scalar multiplication.In mathematics physics and engineering a Euclidean vector (sometimes called a geometric or spatial vector oras heresimply a vector) is a geometric object that has magnitude (or length) and direction.

Definition of a vector. A vector is an object that has both a magnitude and a direction. Geometrically we can picture a vector as a directed line segment whose length is the magnitude of the vector and with an arrow indicating the direction.In mathematics and physics a vector is an element of a vector space. For many specific vector spaces the vectors have received specific names which are listed below.In this section we will take a more detailed look at conservative vector fields than weve done in previous sections. We will also discuss how to find potential functions for conservative vector fields.

The divergence and curl of a vector field are two vector operators whose basic properties can be understood geometrically by viewing a vector field as the flow of a fluid or gas.The example uses push_back to add a new element to the vector each time a new integer is read. Complexity Constant (amortized time reallocation may happen).In this section discuss how the gradient vector can be used to find tangent planes to a much more general function than in the previous section. We will also define the normal line and discuss how the gradient vector can be used to find the equation of the normal line.Removes all elements from the vector (which are destroyed) leaving the container with a size of 0. A reallocation is not guaranteed to happen and the vector capacity is not guaranteed to change due to calling this function.
