Hi professors! i’m interested in WebVR Showroom page by Little Workshop and trying to make similar example. And now i’m stucked at creating a pointer on the floor when raycast hit it. Can anyone teach me how to make it?

I would create a circle sprite, copy the raycast intersection point as the sprite position and then have the sprite look at the normal.
