solved How to set width and height segments when creating a box?

[leota]

When creating a Box using BABYLON.MeshBuilder.CreateBox() I can pass it parameters like width, height and depth, but I don't see widthSegments, or heightSegments for example. Is there a way to do that?

What should be the effect of height or widthSegments?

You can see here: https://threejs.org/docs/index.html#api/geometries/BoxGeometry

(Can open GUI controls at the top right)

Oh ok, kind of subdivisions. We do not have this feature out of the box

That's a shame  Is there any easy workaround to achieve that? Or do I have to modify that Class to implement this change?

[Guest]

If you want to update the class, I will be happy to merge the PR

Everything is here: https://github.com/BabylonJS/Babylon.js/blob/master/src/Mesh/babylon.meshBuilder.ts#L33

The main code is here: https://github.com/BabylonJS/Babylon.js/blob/master/src/Mesh/babylon.mesh.vertexData.ts#L928

I'll give it a try  thanks

Thank you!

The box doesn't have that parameter, but the other shapes do!  The parameter can be used to increase accuracy or reduce poly count.  I think you mentioned cone or cylinder before - it has subdivisions (same with IcoSphere). Also, circle has segments.  So, the other shape creation methods probably have what you are after.  More segments on a square will increase triangles and obviously have the same shape, though!  I can imagine some use cases still.

I see that other shapes have that parameter. On the box would be useful for 3D modeling puposes

Yes it is. It's not exactly what I was looking for, as it applies a uniform subdivision, but it's good enough. Thanks!
