示例1: update
void clipmap_ring::update(const vector & eye_dir_in_object_space)
{
// get quaternion rotations for clipmap
double view_phi = ::acos(eye_dir_in_object_space[2]);
double view_theta = ::atan2(eye_dir_in_object_space[1], eye_dir_in_object_space[0]);
if ( level && !( (::fabs(view_phi - old_view_phi) > VIEW_EPSILON) || (::fabs(view_theta - old_view_theta) > VIEW_EPSILON) ) )
{
return;
}
old_view_phi = view_phi;
old_view_theta = view_theta;
roty = quaternion(vector::Y_AXIS, view_phi);
roty_conj = roty.conjugate();
rotz = quaternion(vector::Z_AXIS, view_theta);
rotz_conj = rotz.conjugate();
