The Library for CMO (also accept NMO, VMO and NMS) File Read/Write. Also the Minimalist Virtools Environment.
|
|
Write with one Library and Load Virtools File Everywhere.
|
|
|
|
## Status
|
|
|
|
This is a long time project.
|
|
This project welcome everyone's contribution, except the employee of Dassault, which created Virtools.
|
|
|
|
## Introduction
|
|
|
|
The aim of this project is creating a universal library which can read / write CMO files or any other Virtools files without any Virtools dependencies.
|
|
This project will not link any original Virtools dynamic library. So this project can be ported to any platform if the compiler supports.
|
|
This project only involving specific Virtools version, 2.1. Other Virtools versions are not considered by this project.
|
|
This project is based on reverse work of `CK2.dll`, `VxMath.dll` and `CK2_3D.dll`. The program [unvirt](https://aluigi.altervista.org/papers.htm#unvirt) created by Luigi Auriemma, which is licensed by GPL-v2, also help my work.
|
|
|
|
**The difference between this project and other Virtools libraries (e.g. [doyaGu/CK2](https://github.com/doyaGu/CK2)), is that we are not focusing on re-creating the whole Virtools engine. We only focus on the Virtools files RW, and we only just implement a minimalist Virtools environment for achieving this.**
|
|
|
|
## Goals
|
|
|
|
The ultimate goals of this project are:
|
|
|
|
* Create a library which can read Virtools file and do not limited on x86 platform by original Virtools implement.
|
|
* Create a universal dynamic library for Ballance Map file loading.
|
|
* Create a Python binding for the loader. And allow user can export Ballance Map from Blender on Linux platform natively.
|
|
* Create a C# binding for the loader to enable that I can load Ballance Map in Godot on Linux / Android platform natively.
|
|
|
|
There is still a long way to go. But I will try my best.
|
|
|
|
## Project Layout
|
|
|
|
* LibCmo: Core library. It is a static library. Link to your program freely because I don't want to process export table things.
|
|
* IronPad: A tiny Crashpad like static library. Used by Unvirt and BMap. Report crash log and coredump only on Windows (Because I assume all Linux users have capacity to enable coredump and deliver it to developer.).
|
|
* Unvirt: Interactive Virtools file viewer. Can provide more detail than Luigi Auriemma's unvirt but only can accept version limited Virtools file (< 4.0 I guess).
|
|
* BMap: A dynamic library which is specific for Ballance Map loading by using LibCmo.
|
|
|
|
## Contributions
|
|
|
|
However, not all contribution will be accepted. Just like I said, we create **Minimalist** Virtools Environment. The basic RW functions is enough. We do not accept complex function implementations.
|
|
There are 3 lists which indicate our accept guideline.
|
|
|
|
### Wanted Features
|
|
|
|
These features will be accepted as soon as possible.
|
|
|
|
* The bug fix of any existing code.
|
|
|
|
### Not Urgent Features
|
|
|
|
These features are in plan, but not urge to merge.
|
|
|
|
* The `CK_ID` remap system of Reader.
|
|
* CK3dEntity hierarchy system.
|
|
* Other CK classes implementations.
|
|
* Non-Virtools 2.1 implementations.
|
|
|
|
### Don't Care Features
|
|
|
|
These features explicitly will not be merged.
|
|
|
|
* Run Virtools file.
|
|
* Plugin system.
|
|
|
|
## Compile
|
|
|
|
This project require:
|
|
|
|
* The compiler supporting C++ 20
|
|
* Littile-endian architecture system.
|
|
* zlib
|
|
* [stb](https://github.com/nothings/stb) (For image read / write)
|
|
* iconv (non-Windows system required)
|
|
|
|
It can be compiled on Windows via sln file. You should set up `LibRef.props` when using sln file to build this project on Windows.
|
|
You also can use CMake file to compile this project on Linux or anything else platform. However CMake may not be updated in time because I develop this project on Windows frequently.
|
|
You may need use this command to configure CMake: `cmake .. -DSTB_IMAGE_PATH="/path/to/stb-image" -DCMAKE_BUILD_TYPE=Release`
