Detailed Description

template<class T, class S>
class gl_sphere< T, S >

Template class for storing spheres with distance values.

This class is essentially the same as the sphere class except that each gl_sphere has a distance value. This value is actually a distance squared to avoid spending time computing square roots.

Member Function Documentation

template<class T, class S> void gl_sphere< T, S >::convert (  ap_array< sphere< T, S > > *  spheres, ap_array< gl_sphere< T, S > > *  gl_spheres )  [static]

Function to convert an array of spheres to gl_spheres. Parameters: spheres  Pointer to an ap_array of spheres gl_spheres  Pointer to an ap_array to hold the computed gl_spheres

template<class T, class S> void gl_sphere< T, S >::compute_distances (  gl_sphere< T, S > *  spheres, int  n, double  eye[3] )  [static]

Function to compute distance values for an array of gl_spheres. For each gl_sphere in the array, the distance squared from the viewing position to the sphere is computed and stored in the gl_sphere. Parameters: spheres  Pointer to an ap_array of gl_spheres n  Number of gl_spheres to process eye  Coordinates of the viewing position
