Interest in 3d printable track pieces for 'classic'?
Hello,
I started working on some 3D printable track pieces base on the OpenLOCK tiling system. The idea is to be able multiple 3D track from a bunch of pieces with some 3D features, w/o the need to go full 3X or to be an experienced modeller. Track is for the 'classic' scale of 1"=15', 2" wide to make things faster to print (and narrower track means more crashes and easier-to-shoot, closer targets of course). Should be possible to make wider (or even narrower !) track, but then it would take a _long_ time to print a full race/combat track. As it's OpenLOCK, it's possible to use other OpenLOCK tiles for scenery (even tough OpenLOCK is meant for 1"=5', we can pretend those walls are just really big to protect the public ;-) ). Anyone interested in trying the pieces on their printers? |

I'd like to but the track I want to make is at least 4" wide, and is banked the whole way around. (Yes, it's the track named for me. :) )

(BTW, I don't live in the U.S., which track would that be ?) |

(In fact: Given the way the corners on the map sheet are drawn, it isn't actually possible for the corners to be banked the way the track desc. says it is.) Oh -- it's one of the tracks in _Car Wars Arenas_; which one should be obvious. :)

I will follow this thread with interest :) I like anything that involves playing with models.

A *very* unfortunate side-effect of that process is that OpenSCAD ends up eating memory like crazy. Creating the STL for that part requires 20+ gigabytes of memory... Quote:
I haven't got Arenas. Back in the day, we used to draw & print tracks for our games rather than play on pre-defined. So we could make the tracks suit out style of play. Also, the Octagon was and still is awesome :-) 3D printing is great for people like me - with no real-life modelling skills :-( Can't paint very well, either. I'll try and publish the pieces (& the code to semi-automate the creation) when the whole process is a bit less hackish than it is now. Last edited by Melkhior; 01-26-2018 at 03:55 PM.

(1) PNG can actually support 16-bit greyscale values. However, many tools won't write this. (2) Yes, in effect each pixel becomes a separate object within OpenSCAD, so achieving a decent resolution gets very expensive very quickly. Still, for this sort of task in OpenSCAD heightmaps are probably still your best bet. While I use OpenSCAD for almost all my modelling for print, in a case like this I'd be distinctly tempted to go to Blender (perhaps working off a base built in OpenSCAD) and its random perturbation modifiers.

https://github.com/rdolbeau/OpenLOCKTrack The STL files are in subdirectory export, but are compressed. They are too big for GitHub, and the STL viewer fails (for me at least) to display them anyway. Quote:
Also, need to find the time to try and paint some of the parts I've already 3D printed. |
