static void MaliSDK::SphereModel::getPointRepresentation ( const float  radius,
const int  numberOfSamples,
int *  numberOfCoordinates,
float **  coordinates 
)
staticprivate

Compute coordinates of points which make up a sphere.

[in]numberOfSamplesSphere consists of numberOfSamples circles and numberOfSamples points lying on one circle. Has to be greater than zero.
[out]numberOfCoordinatesNumber of generated coordinates.
[out]coordinatesDeref will be used to store generated coordinates. Cannot be null.

void MaliSDK::SphereModel::getTriangleRepresentation ( const float  radius,
const int  numberOfSamples,
int *  numberOfCoordinates,
int *  numberOfPoints,
float **  coordinates 
)
static

Create triangular representation of a sphere.

For each point of each circle (excluding last circle) there are two triangles created according to rule described in example below: 

           A2___________.B2
           . \       .  / |
           |. \   .    /  |
           | . A1____B1   |
           |  . |     |.  |
           |   D1____C1 . |
           |  /    .   \ .|
           | /  .       \ .
          D2 .___________C2

Points named A1, B1, C1 and D1 create a first circle of sphere and points named A2, B2, C2 and D2 create the second one (if numberOfSamples is equal to 4). For each loop iteration, for each point lying at one circle of sphere there are 2 triangles created: for point A1: A1 B1 B2, A1 B2 A2 for point B1: B1 C1 C2, B1 C2 B2 for point C1: C1 D1 D2, C1 D2 C2 for point D1: D1 A1 A2, D1 A2 D2

Parameters
[in]radiusRadius of a sphere. Has to be greater than zero.
[in]numberOfSamplesA sphere consists of numberOfSamples circles and numberOfSamples points lying on one circle. Has to be greater than zero.
[out]numberOfCoordinatesNumber of generated coordinates.
[out]numberOfPointsNumber of generated points.
[out]coordinatesDeref will be used to store generated coordinates. Cannot be null.

Parameters

[in]numberOfSamplesA sphere consists of numberOfSamples circles and numberOfSamples points lying on one circle. Has to be greater than zero.
[out]numberOfCoordinatesNumber of generated coordinates.
