Hey folks,

Is it somehow posible to use a POV scene with a camera & objects set to be converted into a vector path for the 2D representation of the 3D scene?

Background of my question: As we are using some LDraw Models as 2D renders in the forums, those will not work well with zooming / scaling. Vector Graphics (SVGs having the paths in XML format) would be ideal to have. As I am no expert when it comes to 3D & rendering topics, I am asking :)

Have not yet invested any efforts into a search on my own, I would like to ask the community 1st if somebody has good knowledge for me to start my journey from.

  • If you have the scene in a 3D modeling software (like Blender), you can export the wireframe or edges as .svg directly.
  • Blender has an "Export SVG" add-on that lets you export 2D projections of 3D models.

So I assume it would be, use Blender with the LDraw loader plugin to create sceneries there and export them (possibly directly) as SVGs..

(next time I should do this before asking in a fresh topic *sigh - I will leave it open if I have further questions as it may include different technologies where I am a bloody newb in..)

I use blender exclusively, then studio..etc, but I am also a retired engineer with all software. If you have anymore questions, maybe I can help.

Nice, thanks.

So my interest would be just still scenes for creating backgroundless single files from a certain (always same) angle and would like to get that as an SVG - question would go toards the export SVG function of Blender:

If it is basically just a very simple arrangemange, transparent background and also very simple 1-2 spot lighting, may the result get me at least the coordinates of the wireframe accordingly? Asking because if your feeling would directly go into "plenty of manual correction efforts needed after export" then I may screw the hole idea already. :D

Why not directly go 3D?
Like the file viewer that’s on the LDraw tracker (or, the older version on BrickLink).
I think it’s free & libre.

I know ThreeJS ovvers a LDraw Loader.

But this would just be a 3D render of a LDraw file (I may have another usecase for that in mind... :D), but my thought was creating Icons to be used as Badges/Ranks etc. Having a js viewport created in the html for every object may be overkill. therefore SVGs offer the exact thing which would allow & is implemented in all browsers and can be utilized with regular elements to be loaded into the view.
