A spherical coordinate consists of two angles (longitude, latitude) and a length (radius).
The formal notation is: vuSpherical = [longitude, latitude, radius]
longitude: angle in x-y-plane, starting with x-axis (counterclockwise) latitude: angle in y-z-plane, starting with y-axis (+z=>+PI/2, -z=>-PI/2) radius: length of vector
0 <= longitude < 2*PI -PI <= latitude <= +PI 0 <= radius < infinity
Definition: if (radius==0), then longitude=0 and latitude=0

Constructor initializing the spherical from an array of floats.
Definition at line 29 of file vuSpherical.cpp. References val. |
|
Constructor initializing the spherical from an vuVector, by transforming the vector into a spherical. Definition at line 36 of file vuSpherical.cpp. References M_PI, M_PI_2, vuVector::norm(), and val. |
Here is the call graph for this function:
|
The destructor.
Definition at line 75 of file vuSpherical.cpp. |
|
Definition at line 165 of file vuSpherical.cpp. |
|
const version of getData()
Definition at line 97 of file vuSpherical.cpp. |
|
Returns the data pointer. The data is stored as a four dimensional float array. The getData() function can both retrieve and modify; it is similar to the [] operator. To warrant the return of a const pointer (for use in other const member functions) explicitly cast the pointer returned to (const). |

|
Getting the longitude.
Definition at line 59 of file vuSpherical.h. Referenced by vu1611_2< SIZE, TYPE >::preview(). |
|
Getting the radius.
Definition at line 63 of file vuSpherical.h. |
|
returns a cartesian vector
Definition at line 150 of file vuSpherical.cpp. References val. |
|
Normalizes the vector to a length of 1. This simply sets the radius to 1. Definition at line 113 of file vuSpherical.cpp. References val. |
|
Performs the 1-norm (manhattan norm) on the spherical.
Definition at line 101 of file vuSpherical.cpp. References val. |
|
Performs the 2-norm on the vector. This is the same as the length operator or radius. Definition at line 107 of file vuSpherical.cpp. References val. |
