RenderableSource.RecenterMode

AI-generated Key Takeaways

RenderableSource.RecenterMode is an enum that defines how a 3D model's local origin is positioned relative to its geometry.
It offers three options: CENTER, ROOT, and NONE to control the placement of the origin.
CENTER positions the origin at the geometric center, ROOT places it at the base aligned with the horizontal center, and NONE applies no recentering.
This enum inherits standard methods from java.lang.Enum, java.lang.Object, and java.lang.Comparable for object manipulation and comparison.

public static final enum RenderableSource.RecenterMode
