Is Lego CAD, website has some pictures: https://www.leocad.org/

LeoCAD uses LDraw Parts Library[0] as a set of "digitallego" bricks.

Also, highly recommend all AFOLs look on the "AWESOME LDraw"[1] — a list of useful digitallego resources (not only LDRaw-related, but also in other formats for various software other than LeoCAD).

Here is my latest screenshot[2,3] with my MOC "Micropolis Mallet Locomotive 0-8-8-0".[4,5]

how did you get such a nice render?

> such a nice render

Guess, you mean this one[0,1,2], right?

If so, I just:

1) modeled MOC in LeoCAD & saved it as `.ldr`;

2) imported `.ldr` into Blender 2.79 (you may use later version) using ImportLDraw addon[3] & just rendered it in "Cycles" render mode (in later versions of Blender its possible use "Eevee" render mode too);

3) final touches was made using AzPainter[4] image editor.

That's all! If you are interested in more LDraw tools and other digitallego resources check the "AWESOME LDraw" list.[5]

There is good guide on ImportLDraw usage for realistic rendering.[6,7]

How long does that take to render on a GPU?

It's highly depend on your hardware.

For this render I used 10+ y/o laptop w/ CPU P4 Dual-Core + integrated GPU Radeon Xpress 1250 (Blender was running in `software-gl` mode) — as a result this model rendered in few hours ( ^_^;)

I suppose this would be great with VR goggles.

I actually build a sort of L**o simulation that uses the LDraw library for pieces in combination with the HTC Vive. You can check it out here:

Looks great!

Possible for sure! Get the following software:

- Blender

- Plugin ImportLDraw - https://github.com/TobyLobster/ImportLDraw

- Either use Blender latest versions (has built-in VR) or try something like Blender XR

I did use ImportLDraw for something a while ago here: https://www.instagram.com/p/Bk3yrj4FC7E/

Here is good tutorial on ImportLDraw usage.[0,1]
