HTMesh was originally intended to be a simple interface to the HTM library for the KStars project tha...
Definition HTMesh.h:57
int size() const
returns the total number of trixels in the HTM.
Definition HTMesh.h:118
void fill()
fills the buffer with consecutive integers
int append(Trixel trixel)
add trixels to the buffer
