Hi, long time no see.

 

 

I am building a browser based app to practise my programming skills.

This app is inspired by Force Vector Design ++ (FVD++).

FVD++ is software that you can use to parametrically design rollercoasters for Nolimits 2.

The basic principle is that you tell FVD++ what the normal force, lateral force, and banking of the rollercoaster should be at each point in time.

Using physics, it generates a track that meets those conditions.

This results in professional grade, smooth rollercoaster designs.

 

My app works in the same way.

 

The blue line in the graph represents the normal force.

The red line represents the roll (banking).

I have not implemented lateral forces yet. They are assumed to always be zero for now.

 

Have a look at this very alpha build. At the end of the video I show you a simulation of the train traversing the track:

as an avid FVD++ user, this looks very nice, well done

Thanks CrayCray!

 

I have recorded an update video on the latest features that I have implemented:

Here is another update:

 

- Launches and Lift Hill

- Detailed renders of the Track and the Flexis

- Custom color schemes for the Track, Crossties and Train

- Toggle Edges (cartoony / CAD visuals)

- Light and Dark mode for the whole application

- Bonus: download size of the whole application is thus far only 588 kB!
