Example usage for javax.media.j3d Transform3D setScale

Introduction

In this page you can find the example usage for javax.media.j3d Transform3D setScale.

Prototype

public final void setScale(Vector3d scale) 

Source Link

Document

Sets the possibly non-uniform scale component of the current transform; any existing scale is first factored out of the existing transform before the new scale is applied.
