You can edit the geometry position vertices, or create three plane geometries, transform them (translate and rotate), then merge them with [mergeGeometries](https://threejs.org/docs/?q=Buffer#examples/en/utils/BufferGeometryUtils.mergeGeometries). That’s one option among others, here is working [example](https://jsfiddle.net/pvjo3smx/).

If you need a curved plane check this thread:

> Hi. Discovering threejs since one month with an Oculus. Wow. WOW. Seem’s i found a really great toy for the rest of my addict dev life. I already made some basic stuff successfully. I’m learning three, i dev vanillia js since a long time. I found a lot of answers in discourse, google, doc … I’m using the dev branch of threejs (because i’d like to understand how gui.dat in vr mode is working without a raytracer slight_smile ) My question is : how to draw a simple plane (or rectangle) curv…

Or this one using a path:
