; FitMesh Example
; ---------------
; In this example we will demonstrate the use of the FitMesh command.
; First we will use FitMesh on a semi-transparent blue box. This will represent the dimensions we will
; be using with FitMesh.
; Then we will use these dimensions on a red cone, so that it appears to fit inside the box when the
; space bar is pressed.
; The first time the space bar is pressed a uniform FitMesh will be performed, which means the cone
; will be scaled equally along all axis so that at least one axis fits the dimensions specified.
; The second time the space bar is pressed a non-unifrom FitMesh will be performed, meaning the cone
; will be scaled non-equally along all axes so that all axes fit the dimensions specified.
