Generating Points for a Geodesic Sphere

The code we’re about to explore was developed for testing purposes. It calculates half a sphere and then duplicates the top half onto the bottom, omitting the meridian line of points. This technique is based on the concept of a geodesic dome, which you can learn more about on Wikipedia.

static int x, y;
size = 2;
for (x = 4; x < (4 * DIVISIONS); x += 4) { 
  size += x * 2; 
} 
size += x; 
_sphereArray = new Pnt [size];

static GLfloat scaler, scaler2;
Pnt *_index, *_pointer;

_index = _sphereArray;
_index->x = 0.0f; 
_index->y = 1.0f; 
_index->z = 0.0f;
_index++;

for (x = 0; x <= DIVISIONS; x++) {
  scaler = (PI / 2.0f) * ((GLfloat)x / (GLfloat)DIVISIONS);
  _pointer = _index + x;

  for (y = 0; y < x; y++) {
    scaler2 = (PI / 2) * ((GLfloat)y / (GLfloat)(x));
    _index->x = sin(scaler) * cos(scaler2);
    _index->y = cos(scaler);
    _index->z = sin(scaler) * sin(scaler2);

    _pointer->x = -_index->z;
    _pointer->y = _index->y;
    _pointer->z = _index->x;

    (_pointer + x)->x = _index->z;
    (_pointer + x)->y = _index->y;
    (_pointer + x)->z = -_index->x;

    (_pointer + x * 2)->x = -_index->x;
    (_pointer + x * 2)->y = _index->y;
    (_pointer + x * 2)->z = -_index->z;

    _index++;
    _pointer++;
  }

  _index += x * 3;
}

for (_pointer = _index - 1 - ((x-1) * 4); _pointer != _sphereArray; _pointer--) {
  _index->x = _pointer->x;
  _index->y = -_pointer->y;
  _index->z = _pointer->z;
  _index++;
}

_index->x = _pointer->x;
_index->y = -_pointer->y;
_index->z = _pointer->z;

To understand the code better, let’s break it down into sections and explore each step thoroughly.

Section 1: Initialization and Sphere Size Calculation

The first section initializes variables and calculates the size of the sphere based on a defined variable called DIVISIONS. This variable represents the number of latitudinal divisions along half a hemisphere. By increasing the value of DIVISIONS, you can create a more detailed and complex sphere.

Section 2: Generating Sphere Points

In this section, the code generates the points that form the spherical shape. It uses trigonometric calculations to determine the position of each point on the sphere’s surface. These calculations consider the latitude (x) and longitude (y) of each point.

Section 3: Duplicating the Top Half

After generating the points for the top half of the sphere, the code duplicates them onto the bottom half. By mirroring the points, we complete the shape of the sphere. This process involves flipping the signs of the x and z coordinates for each duplicated point.

FAQs

Here are some commonly asked questions about creating a soccer ball-like shape in code:

  1. Can I customize the number of divisions in the sphere?
    Yes, the code allows you to adjust the number of divisions in the sphere by modifying the DIVISIONS variable. Increasing this value will result in a more detailed sphere.

  2. What programming language is this code written in?
    The code provided in this article is written in C.

  3. Can I apply textures or colors to the generated sphere?
    Yes, once you have the points for the sphere, you can apply textures or colors to each point based on your preferences. However, implementing textures or colors is beyond the scope of this article.
