Creating BVE5 structure (.x) with SketchUp – Part 3

In this post we will create a background structure for BVE5. Basically, it is an open cylinder with a texture image applied on the inner side surface. It's a simple structure, but it might a bit tricky to apply the texture image on the cylinder surface. The radius of the cylinder will determine the distance of the background and it should be less than 1000 meters.

Creating BVE5 structure (.x) with SketchUp – Part 2

In the previous article, we discussed how to create an X object using SketchUp. Let start creating BVE5 structure with  a simple structure, i.e. the ground structure. Technically, it is a plain rectangular object in a horizontal position.

Creating BVE5 structure (.x) with SketchUp – Part 1

BVE5 Trainsim structure might be easier to create, compare to the older version of BVE (including OpenBVE).  BVE5 Trainsim use Direct3D object (.x) format. It is a simple file containing geometry meshes and material information that can be viewed in the DirectX Viewer. For more information about Direct3D file format, please refer to https://msdn.microsoft.com/en-us/library/windows/desktop/bb174837(v=vs.85).aspx or https://en.wikipedia.org/wiki/.x

Direct3D object can be create using 3D modeling software, and then converted to .X format using specific extensions or plugin. Here, we are using two versions of SketchUp for this purpose.

I am sorry for having kept you waiting for so long, here is another “nightly build” released. There only minor changes for OpenBVE/older BVE route builder in this released. Major changes are for BVE 5 Trainsim route builder, but it’s still far from complete and might not stable.

Please take note, this version is still under development, so it’s might not work as expected.

“Nightly builds” released – v1.2

This version is under development, it might not stable. You can use this version as the existing version is no longer functional due to changes in the latest version of Google Maps JavaScript API. However, it should be noted the following feature is being developed and is not yet available.

• vertical curve for BVE5 Trainsim (including distance correction).
• underground feature

Therefore if you develop route for BVE5 Trainsim, please use legacy gradient only.

Vertical Curve

 

Vertical curve is the curve in vertical layout to connect two track gradients together whether it is for changing from an upgrade to a downgrade (summit), changing from a downgrade to an upgrade (sag or valley), changing in two levels of upgrades or changing in two levels of downgrades.

(縦断曲線)

勾配が変化する地点において、一点で突然勾配を変化させると路線に「折れ」が生じてしまい、走行性を阻害したり、路面に車両の底が接触したりするなど好ましくない。そこで、勾配の変化点では縦断方向に曲線を挿入し、徐々に勾配を変化させる。この曲線を縦断曲線、または英語表記からバーチカル・カーブ(vertical curve)と呼び、とくに鉄道においては縦曲線と呼ぶ^[2]。縦断曲線は二次曲線（放物線）が用いられるが、円弧で近似できるため、半径を用いてその大きさを表す。

Running GB Maps with local web server

Did you know that GB Maps can be run using a local web server, i.e. localhost? With this you can now use Google Chrome because there is no more restriction of local cache.
You can use any web server engine, e.g. Apache, Nginx, MS IIS, and etc. You can also use a small web server, such as BabyWeb.
