Detailed Description

Display a list of points.

Display a list of 3D points. It is made of tiny small cubes showing where the points are. Points coordinates are 3 float values (x,y,z).

Points are in world coordinates. If you are using volume coordinates, scale the points to the correct volume size before. The following example shows how to display the points with a volume displayed in a centered unit box:

   glTranslatef(-0.5f,-0.5f,-0.5f);
   glScalef(1.0f/width, 1.0f/height, 1.0f/depth);

   points.display();

For better results use the following OpenGL initialization:

   glShadeModel(GL_SMOOTH);
   glEnable(GL_DEPTH_TEST);
   glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
