What is the best way to apply a transform matrix to a mesh?

Questions
1

I have been starting to use xr features and have noticed that there is a transformationMatrix specified as an argument for a IWebXRPlane. If you construct a mesh using the IWebXRPlane polygone definition, what is the correct way to apply the transform to the mesh?

Also, if you already have a mesh and want to apply a transform matrix, what is the best way to do so?

Thanks!

Hi!

The plane objects are delivered by webxr itself, so constructing them yourself won’t work as you might expect. When a plane is detected Babylon will create the object for you and you will be able to use it. How? I always prefer to see code:

Line 144 will show you how to deconstruct the matrix to fit your object.

I hope this helps!
