I have started going the route of porting to Linux native code.
I am calling it "LinuxRails" for now.
It will be native Linux C++ code.
It looks like I will be using SDL for a support package.

The ORTS source is C#, which makes using the ORTS source code impossible.
For that reason I am writing my own engine with native file formats.
This is not my first code re-writing project.

Currently, I am using ORTS source code to write the decoders for the MSTS file formats,
and write Linux native file readers for the MSTS files.
I am using a file reader structure that I have used before,
not the ORTS decoder-in-a-constructor.

Much of the 3D drawing will come from other SDL projects.

I am not sure about using the quads from the MSTS files.
As this is the usual walker-vehicle viewpoint as in most first-person games,
the usual position and two angles of rotation should be adequate.

Estimated time to first play is at least 3 years.

It looks like we are both trying a port. I had the same trouble as you did in untangling the C# - but in my case I am using C as I decided it was faster (after reading Stroustrup's C++ manual).

The code is on github:
https://github.com/djw-zr/ZR

I am using the 'free' zig-zag layout and the code has reached the stage where I can run an engine along the track and change points/switches. At present I am trying to get the wheels to rotate. This involves reading the engine and wagon files (done on my home computer) - to get the wheel diameters and then adding the extra matrix transformation when displaying the engine shape file.

Regards,

David.

p.s. I was waiting to update this message board until after the wheels were rotating as this seemed to be the basic system anyone might be interested in.!

There is also a discussion of Openrails/MSTS and Linux here.. This now includes a link to a Linux version using C++ and OSG (Open Scene Graph). It is written by dajones and has been going since 2008.
