Detailed Description

2D drawable component for rendering rectangular primitives.

Represents a simple 2D quad used for sprites, UI widgets, text, or procedural materials. Provides a lightweight implementation of a 2D drawable with transform and material properties inherited from Drawable2D.

Note
Not copyable or assignable.
