Class SectionBox

Creates a new SectionBox gizmo controller.

Determines whether the section gizmo applies clipping planes to the model.

When true, renderer.section.active is enabled.

Determines whether the gizmo is interactive (i.e. responds to pointer events).

When true, pointer events are registered and box handles can be dragged.

Dispatches when the user finishes manipulating (dragging) the box. The payload is the final THREE.Box3 used for clipping.

Dispatches a boolean indicating pointer hover state on the box handles:

• true if the pointer has entered a handle
• false if it has left or no handle is hovered

Dispatches when any of the following properties change:

• clip (clipping planes active)
• visible (gizmo visibility)
• interactive (pointer inputs active)

Determines whether the section box gizmo is visible in the scene.

Disposes of the gizmo and input event listeners, cleaning up related resources.

After disposal, this SectionBox instance should no longer be used.

Returns a copy of the current section box. To programmatically update the box, see setBox.

Resizes the section gizmo to match the given box, optionally expanded by a padding. After resizing, this method also updates the renderer's clipping box.

Updates the section box to match the current size of this.section.box.

Call this if the renderer's section box is changed by code outside this class.
