Changelog
=========
Version 0.8.0 (2022-10-21)
--------------------------
Models and textures:
- Add support for MD5 animated models (thanks to
https://github.com/AntonioND/dsma-library): Introduce tool md5_to_dsma to
convert them to a format that Nitro Engine can use.
- Add support for OBJ static models: Introduce tool obj2dl to convert them to a
format that Nitro Engine can use.
- Introduce tool img2ds to convert images in many popular formats (PNG, JPG,
BMP, etc) to DS textures (PNG is still recommended over other formats, as it
supports alpha better than other formats).
- Drop support for MD2 models (static or animated).
- Remove NDS Model Exporter, Nitro Texture Converter, md2_to_bin and md2_to_nea.
The animation system has been refactored (but NEA files don't work anymore, so
you need to update your code anyway).
General:
- Huge cleanup of code style of the codebase.
- Cleanup of all examples. Add the original assets and textures used in all
examples to the repository, along scripts to convert them to the formats used
by Nitro Engine.
- Implement a better way to have debug and release builds of the library.
Notes:
- You can still use textures converted with Nitro Texture Converter or NDS Model
Exporter, and you can still use any model exported with NDS Model Exporter or
md2_to_bin. However, support for NEA files has been removed (it had awful
performance, and it was just a bad way to do things), so any file converted by
md2_to_nea won't work anymore.
- The reason to replace most tools is that several people had issues building
them. All the new tools are written in Python, so they don't need to be
compiled.
Version 0.7.0 (2019-6-14)
-------------------------
- Pushed to GitHub.
- Major cleanup of code.
- Clarify license.
- Reworked tools to build under Linux and Windows.
Version 0.6.1 (2011-9-1)
------------------------
- Fixed identation in all code. Now it isn't a pain to read it (not as much as
before, :P). Also, a few warnings fixed (related to libnds new versions).
Version 0.6.0 (2009-6-30)
-------------------------
- The functions used to modify textures and palettes now return a pointer to the
data so that you can modify them easily.
- Each material can have different propierties (amient, diffuse...). You can set
the default ones, the propierties each new material will have, and then you
can set each material's propierties individually.
- New texture and palette allocation system, it is faster and better.
Defragmenting functions don't work now, but I'll fix them for the next
version.
- Added a debug system. You can compile Nitro Engine in "debug mode" and it will
send error messages to the function you want. Once you have finished debugging
or whatever, just recompile Nitro Engine without debug mode.
- Window system renamed to Sprite system. You can set a rotation and a scale for
each one.
- The most important thing... The animation system has been improved, and now
animated models are drawn using linear interpolation (you can disable it,
anyway).
- As a result, I've modified the converters, so you'll have to convert yout
animated models again.
Version 0.5.1 (2009-1-28)
-------------------------
- Minor bugfixes.
Version 0.5.0 (2009-1-5)
------------------------
- Text system and camera system optimized. New functions for the camera system.
- NE_TextPrintBox and NE_TextPrintBoxFree slightly changed. They can limit the
text drawn to a number of characters set by the coder.
- Some functions made internal. Don't use them unless you know what you are
doing.
- Fixed (?) at least the 2D projection.
- HBL effects fixed.
- Touch test functions.
- NE_UPDATE_INPUT removed.
- It now supports any BMP size, and BMP with 4 bits of depth.
- Arrays made pointers, so there is more memory free when you are not using
Nitro Engine. You can also configure the number of objects of each systems you
are going to use.
- NE_TextPalette replaced by NE_Palette.
- You can clone materials to use the same texture with different colors. This
doesn't have the problems of cloning models.
- Added functions to remove all palettes and textures.
- Fixed NE_End().
- NE can free all memory used by it, and the coder can tell NE how much memory
to use.
- Texture drawing system improved a bit.
- NE_PolyFormat simplified.
- Some bugfixes, code reorganized, define lists converted into enums.
- Clear bitmap supported, this is used to display an bitmap as rear plane. Each
pixel can have different depth. This needs 2 VRAM banks to work.
- Solved some problems with 2D system and culling.
- Nomad NDS_Texture_Converter is no longer included, if you want it, look for it
in Google.
- Added Nitro Texture Converter, made by me. Open source, and it exports various
levels of alpha in the textures that can handle it. It does only accept PNG
files.
- NE now accepts any texture size. NE_SIZE_XXX defines removed as they are not
needed now.
- Added a couple of examples.
Version 0.4.2 (2008-12-14)
--------------------------
- Fixed 2D system (textures were displaying wrong on 2D quads) and text system
(paletted textures sometimes were drawn without palette).
- Modified MD2_2_NEA, MD2_2_BIN and bin2nea to work in linux. Thanks to
nintendork32.
- Added a couple of examples.
Version 0.4.1 (2008-12-12)
--------------------------
- Lots of bugfixes. Specially, UV coordinates swapping fixed.
- Added a function to draw on RGBA textures ^_^.
- Fixed MD2_2_NEA and MD2_2_BIN. You'll have to convert again your models.
- Updated to work with latest libnds. There is a define in case you want to use
an older version.
Version 0.4.0 (2008-10-15)
--------------------------
- Added MD2_2_NEA (converts an MD2 model into a NEA file that can used by Nitro
Engine) and MD2_2_BIN (Converts the first frame of an MD2 model into a display
list). Display lists created by them are really optimized.
- Updated DisplayList_Fixer. Now it can remove normal commands too.
- Added a text system. It can use fonts of any size. ^^
- Added some simple API functions (buttons, check boxes, radio buttons and slide
bars).
- Fixed 2D projection.
- Removed some internal unused functions to save space, and made 'inline' some
of the rest.
- Functions that used float parameters modified so they use integers now. You
can still use some wrappers if you want to use floats. This will let the
compiler try to optimize the code.
- Animated and static models are now the same. You can move, rotate, etc them
with the same functions.
- Now, you can 'clone' models so you can save a lot of RAM if they are repeated.
- Renamed lots of model functions. Take a look at new examples or documentation.
- NE_Color struct removed (I don't even know why I created it...).
- Examples updated to work with last version and added examples of clonning
models, API and text system.
- libnds' console is not inited with Nitro Engine. You will have to init it
yourself with NE_InitConsole or libnds' functions.
Version 0.3.0 (2008-9-16)
-------------------------
- Support for animated models (NEA format) and a program to make a new NEA file
from many models (in bin format).
- 2D over 3D system. You can draw easily quads (with or without texture) as if
they were drawn using 2D.
- Basic physics engine (gravity, friction and collitions). It does only support
bounding boxes for now.
- Added a function to delete all models, animated or not.
- Window system, very simple. I will make some API functions in next versions.
- Nitro Engine compiled as a library to include it easier in projects and save
space.
- Examples folder organized a bit and added some new examples.
- Nitro Engine is now licensed under the BSD license.
Version 0.2.0 (2008-8-31)
-------------------------
- Added effects like fog and shading, functions to load BMP files and convert
them in textures and more examples.
Version 0.1 (2008-8-24)
-----------------------
- Includes 2 examples, documentation, tools to export models from the PC, the
license and full source.
