- The purpose of this file is to attempt to describe the changes
- made since the last release. I should have started this from the beginning,
- and I am sorry that I didn't. I also apologize for the lack of documentation.
- Make sure to look at the README file, though, for information.
-
- With that, here is the list of changes:
-
- Changes from T3DLIB38 to T3DLIB39 - 2/13/93
- -------------------------------------------
- o Bug in Rayshade, VORT, and POV output... thought objects were lights. Fixed.
- o Added "TexIt" to registered release... Applies textures to objects.
- No source code will be provided for TexIt, sorry.
-
- Changes from T3DLIB37 to T3DLIB38 - 1/31/93
- -------------------------------------------
- o I added a date to the CHANGES listing. (So you can now tell what I was doing
- instead of watching SuperBowl '93. :-)
- o I made a change to the method of Shareware release. See the README.R38 file.
- o DOCUMENTATION!!! Wheee!!! See the ".doc" files provided with the executables.
- o Made the entire suite compile under SAS/C 6.2 without errors or warnings.
- o New program: bumpit - uses algorithmic noise (courtesy of Charles Congdon...
- Thanks, Charles!) to procedurally disturb the points on an object.
- o New program: spherize - conforms the points of an object to a unit sphere.
- o New program: mbb - Calculates and prints the Minimum Bounding Box of an object.
- o New program: set_texture_path - changes root path assignment for all textures.
- o New program: set_brush_path - changes root path assignment for all brushes and
- stencils (stencils are an old Turbo Silver thingy).
-
- Changes from T3DLIB36 to T3DLIB37
- ---------------------------------
- o Not everybody liked or understood the concept of "filters" so I have,
- where possible, made the conversion programs accept command-line arguments,
- instead of forcing people to use pipes or redirect the stdin and stdout of
- the filter.
- o I also made it so that all programs, when given the "-help" flag, print
- usage information.
- - Support for LightWave3D object files has been started, but not finished.
- o Support for the undocumented "TXT2" chunk has been added. This is the
- Imagine 2.0 "texture" chunk that includes parameters, texture axis
- information, a boolean for "Apply to Children", and subgroup restrictions.
- * Support for Staging files. F/X aren't supported yet, possibly others.
- Reads/writes text *and* IFF "staging" files, in the same manner as TTDDD/TDDD
- files.
-
- Changes from T3DLIB35 to T3DLIB36
- ---------------------------------
- o Minor update that fixes a T3DLIB bug that was tickled by "igensurf"...
- If the first line had a valid TTDDD command on it, readwrite croaked.
- Two lines fixed it. Sorry about that.
-
- Changes from T3DLIB34 to T3DLIB35
- ---------------------------------
- o Thanks to Scott Ellis, Amiga executables are provided in the files:
- T3DLIB35_68000exe.lha (68000, non-FPU version)
- T3DLIB35_68030exe.lha (68030, FPU version)
- Note that these were compiled with SAS/C, and so they do not have that bogus
- restriction of running only under version 2.04 of the operating system like
- the R33 version of the executables had!
- Yahoo! Thanks, Scott!
- o So as to reduce the amount of confusion, I went ahead and bumped the revision
- number, because the README file changed, as did the Makefile.Amiga.
-
- Changes from TTDDDLIB33 to T3DLIB34
- -------------------------------------
- o Added support for AutoCAD's DXF files (without having AutoCAD). If someone
- wishes to send me DXF examples that include "Layers" for use in assigning
- different levels in an object's hierarchy, I will attempt to implement that
- too.
- o Added support for POV-Ray 1.0. The input file format is rather restrictive,
- in my humble opinion (specifically regarding describing complex object
- hierarchies and applying textures to unions of shapes), which forced me to
- color ("texture") each triangle individually instead of applying a texture
- to a child object and overriding it on a triangle-basis if need be.
- Drew Wells, leader of the POV-Ray project, says that a future version will
- address my concerns. Anyway, all this means that the POV files will be
- quite large for a medium- to high-complexity object.
- o I added more documentation to the README.R34 file, describing uses of this
- package. Yes, better and more complete documentation must still be written.
- o Essence 1.0 has already shipped. :-) (Just thought I would throw this in
- here even though it has nothing to do with T3DLIB. :-)
- o I changed the names of the archives to T3DLIB, which is much easier to say.
- :-)
- o I removed the "ext2int" program, which was simply a link to "readwrite"
- anyway.
-
- Changes from TTDDDLIB31 to TTDDDLIB33 (ooops, forgot to update this at 32)
- -------------------------------------
- o First, the "readwrite" filter (aka ext2int) can now output Imagine object
- files directly (in the TDDD format) when given the "-tddd" option (or "-t" for
- short). Also, for some time now it has already had the ability to read either
- TDDD *or* TTDDD files without you having to specify which is which.
-
- o This release supports a number of new Imagine 2.0 TDDD "chunks", including
- the following:
-
- SPC1 - Specular default
- PRP1 - Object properties
- EFLG - Edge flag
- FGRP - Face subgrouping
-
- Changes from TTDDDLIB29 to TTDDDLIB31 (yep, no release 30)
- -------------------------------------
- o Fixed a bug in writetddd that caused incorrect reading of real numbers
- such as "-.5" with no digits before the decimal point. Thanks, Paul,
- for pointing this out! Also added exponential notation support in case
- some program decided to generate them.
-
- Changes from TTDDDLIB28 to TTDDDLIB29
- -------------------------------------
- o I have decided to include "writetddd" with the distribution so that it
- will be much more useful to even those people who do not register for
- this shareware (the majority, I'm afraid). Now you can pipe the output
- of any of the programs that create TTDDD file through "writetddd" and
- get Imagine-compatible objects.
-
- Changes from TTDDDLIB27 to TTDDDLIB28
- -------------------------------------
- o Ooops. I forgot to include "merge.c" in the archive.
-
- Changes from TTDDDLIB26 to TTDDDLIB27
- -------------------------------------
- o Speed-up and bug fix (which caused it to hang) in "merge.c"
-
- Changes from TTDDDLIB25 to TTDDDLIB26
- -------------------------------------
- o Added "merge_World()" function in "merge.c"
- This routine optimizes points and edges in an object hierarchy
- by removing duplicates.
- o Added the "-m" flag to "ext2int" to optionally "merge" the object
- before outputing.
-
- Changes from TTDDDLIB24 to TTDDDLIB25
- -------------------------------------
- o Bug fix in read.c and readtddd.c
- read.c was calling an external "malloc_arrays()" such that its static
- variables "defclst", etc. were not being used.
