I’ve been contemplating on how to make the wall functionality of a level-editor similar to the one in The Sims. I’ve found a few questions online regarding something similar, but I ran into some other issues than those discussed there, and I’m really curious on how the programmers actually solved th…

It looks amazing. Do you have any tricks to share?

users may want to undo/redo, and want to place windows and doors within the walls, change the colours, thickness, height, and even curve them. Sweet home 3d, which my program is based on, solves all of these problems really well.

I use an approach similar to mjurczyk’s 2nd suggestion. But I didn’t use the shape geometry or extrude. I created cube buffer geometries manually from 2d vectors with a starting and ending point. I manually calculate all angles for joins. The hard work paid off, since I was able to adapt it to make …

In this variant the calculation is much clearer. ProfiledContourGeometry MultiMaterial Will also be in the Collection of examples from discourse.threejs.org in 2019.

With my version there are the following possibilities [2020-06-06 18.30.18] The surfaces overlap and raise artifacts. [2020-06-06 18.33.30] One keeps the distance corresponding to half the wall thickness. (mirrored here) [2020-06-06 18.32.55] … with the other material variant.

I see. These are difficult issues to solve, and probably demand another approach if one were to merge everything.

It is not difficult, for example, if you only need these right-angled T - pieces. Maybe this is also a possibility: https://hofk.de/main/discourse.threejs/2019/Shapes/Shapes.html from the Collection of examples from discourse.threejs.org

Merging wasn’t a problem I was trying to solve. [image]
