Using template parameter dependent name lookup it is
now possible to create to_nasal_helper overloads
for custom types and having them used for automatic
type conversion with binding methods/member on
nasal::Ghost objects.
It is now possible to register all types of member function
and free functions as methods for nasal::Ghost objects.
The return value and arguments are converte automatically
to the required types.
Also usage is simplified by removing replacing the old
method and method_func with a single method function
which only needs a name for the method and something
callable.
Check for the 3rdparty dir in the parent of build dir, not the parent of the source dir. For the recommended build layout, this is the same location, but for super-builds using fgmeta it's not (and the source tree should not be touched).
If this causes anyone issues, please let me know, since it's possible more flexibility is needed to set the path explicitly.
- Improved Nasal/C++ bindings will follow. For now just test if
all compilers are happy with intended approach.
- Add to_nasal overload for std::map<std::string, T>.
A user_data pointer and another pointer to an optional
deleter function is stored in unused parts of the naPtr
union. The previous behavior of extension functions does
not change. Only one additional boolean comparison is
required upon each function call to check whether user
data is available.
The levels at which page nodes are built is exposed by an
osg database pager option SimGear::SPT_PAGE_LEVELS which could
contain a blank separated list of levels where paging occurs.
Also the database pagers paths are searched for static lower
level of detail tiles in case they are available.
This defers loading the models into a paged lod node
that is evaluated at a later point in time. That should
help for memory problems with higher visibilities.
