I installed the current version of 3DLDF in CTAN:graphics/3DLDF/
These are the Release Notes:
----- Forwarded message from Laurence Finston <lfinsto1 at gwdg.de> -----
Release of 3DLDF 1.1.5.
3DLDF is a GNU package for three-dimensional drawing with MetaPost
output.
It is available from http://ftp.gnu.org/gnu/3dldf and other ftp
servers.
Please see the author's website,
http://wwwuser.gwdg.de/~lfinsto1
and
http://www.gnu.org/directory/graphics/3D/3DLDF.html
for more information.
In release 1.1.5, I've tied up some loose ends. I wanted to do this
before starting on the input routine.
* Added `const real step' argument to the version of
Ellipse::intersection_points() that takes an Ellipse
argument.
* BUG FIX: Added `touch 3DLDFmp.mp' to the `3DLDFmp.mp' target in
3DLDF-1.1.5/CWEB/Makefile.am. This ensures that
TeX and dvips will be run if MetaPost is run on `3DLDFmp.mp'. This happens if
`3DLDFput.mp' is newer than `3DLDFmp.mp', but the latter isn't
changed, so TeX and dvips
weren't being run. I'm surprized nobody's complained about this.
Not yet documented in the _3DLDF User and Reference Manual_.
* Added `PHONY' targets as synonyms for certain targets:
`cpl' for `3dldf'. For compiling and linking `3dldf'.
`mp' for `3DLDFmp.mp'. For running MetaPost on `3DLDFmp.mp'.
`ldf' for `3DLDFput.mp'. For running `3dldf'.
Not yet documented in the _3DLDF User and Reference Manual_.
* It is now possible to ``typedef'' `real' to either `float'
or `double'. This means that `real' can now be made a synonym
for either `float' or `double' by using a `typedef'
declaration. `real' is typedeffed to `float' by default.
* Added `const bool ldf_real_float' and
`extern const bool ldf_real_double'
for use in non-conditionally compiled code.
They are set according to the values
of `LDF_REAL_FLOAT' and `LDF_REAL_DOUBLE'.
* `Transform::epsilon()' and `Point::epsilon()' now return
different values, depending on the values of the preprocessor macros
`LDF_REAL_FLOAT' and `LDF_REAL_DOUBLE'. I have not yet tested
whether good values are returned when `real' is `double'.
* `MAX_REAL' and `MAX_REAL_SQRT' are no longer constants.
Their values are set at the beginning of `main()'. However,
users should not change their values. `MAX_REAL' is the
second-largest `float' or `double' on a given machine. This
now works for all common architectures.
* Added `namespace System' containing the following functions:
`get_endianness()', `is_big_endian()',
`is_little_endian()', `get_register_width()',
`is_32_bit()', `is_64_bit()', and the template function
`get_second_largest()'.
`namespace System' and its functions are documented in
`system.texi', which is new in edition 1.1.5 of the
_3DLDF User and Reference Manual_.
* Replaced the various `create_new_<type>()' functions with the
template function `create_new()'. The latter is documented in
`creatnew.texi', which is new in edition 1.1.5 of the
_3DLDF User and Reference Manual_.
* Added the file `3DLDF-1.1.5/CWEB/cnepspng.el' to
the distribution. It contains the definitions of the Emacs-Lisp
functions `convert-eps' and `convert-eps-loop'.
* Added the files
3DLDF-1.1.5/CWEB/exampman.web and
3DLDF-1.1.5/CWEB/examples.mp to the
distribution. They contain the C++ and MetaPost code,
respectively, for generating the illustrations in the
_3DLDF User and Reference Manual_.
