Introduction to Scalars and Vectors

In basic physics, scalars and vectors are the same thing. While this is true, they are not the same thing in computer graphics. In computer graphics, a scalar is a mathematical value that represents an object’s position in space, while a vector is a direction. Keep in mind that a scalar simply has a higher magnitude than a vector. The following illustration (Movie 1) makes this clear.

A scalar and a vector are both set up in the x-y plane, but the scalar has a higher magnitude than the vector. So when you multiply a scalar by a vector, the result is a scalar product, while when you multiply a vector by a scalar, the result is a vector product. A scalar and a vector are both measured in units of distance, such as in meters or feet. Therefore, a scalar’s range is the range of values along a vector, while the range of values for a vector is the range of values along a scalar. A scalar and a vector are related mathematically by a dot product, which is simply the dot product of their components.

A dot product can be defined as the slope angle between any two vectors. For example, if a vector A is moving east at an angle it towards the earth, then the vector b is moving east at the same angle towards the earth as well. If you take the components of both components and divide them by their slopes, you get the product of the two components. The magnitude of the component is the square of the angle between them, while the magnitude of the integral term is the sine of the angle between the componentwise components. Because these integral values are summed, they are called sine products.

The magnitude of a vector quantity can also be found by dividing it by the direction that it is traveling. For example, the magnitude of the angle formed by the vector A and its axis of rotation is the same as the magnitude of the angle formed by the vector B and its axis of rotation. When this happens, the vector product is zero. In mathematical notation, this can be written as the dot product. To find the magnitude of a vector quantity in 3D, multiply each component by the orientation angle for the corresponding axis of rotation, and the result will give you the magnitude of the vector.

Vector particles can also be thought of as sets of arithmetic or geometric mean motion. The direction of motion of a scalar is always directly opposite to the direction of motion of a vector. In other words, if you have a scalar that looks like it is going east, then it will actually be traveling east, unless of course it is traveling North.

Vector mathematics has long been used in engineering design. This is because it is a powerful tool for representing complex physical systems as sets of numerical values. For instance, the magnitude of a scalar which is orthogonal to the x-axis is the set of vector directions that are parallel to the x-axis. Thus, these vectors can be easily transformed into another system such as a frustogram or geometry of a frustration plane.

One way to represent a vector as a set of numeric values is to write it as a matrix in a vector system such as matrix algebra. The matrix element for each direction is the magnitude of the vector along that direction. Each cell in the matrix represents a single direction. This form of vector mathematics is often used in engineering design when converting real-valued signals to some form of scalar or other unit vector.

It should be noted that in all cases, the magnitude of a scalar or vector must be expressed in units of the units of a unit direction. Therefore, if a signal is measured in millimeters, then the magnitude of the signal, expressed as a scalar in inches, would also be measured in millimeters. In general, the range of measurable values of a vector is the range of its center of mass or central velocity. Note that it is possible for a vector to have a zero vector energy; however, it is also possible for a vector to have zero momentum. In scalars and vectors, momentum refers to the effect that an object has on its own gravity.
