+># 3D Sprites and Animated Sprites
+
+This project demonstrates the usage of Sprite3D and AnimatedSprite3D in 3D
+space.
+
+Both Sprite3D and AnimatedSprite3D are nodes that allow 2D textures or
+animations to exist within a 3D world. They are particularly useful for stylized
+or lightweight 3D effects using traditional 2D assets.
+
+- **Sprite3D:** A node that renders a single 2D texture or frame in 3D space. It
+  can be rotated, scaled, and positioned like any 3D node. Optionally, it can
+  behave as a billboard to always face the camera.
+- **AnimatedSprite3D:** Extends Sprite3D by supporting frame-based animation. You
+  can assign a SpriteFrames resource to play sequences of textures, making it
+  suitable for character sprites, visual effects, or flipbook-style animations in
+  3D.
+
+Both types can be combined with custom shaders to simulate outlines, lighting
+effects, or other visual enhancements. In most scenarios, Sprite3D is used for
+static images or simple animations, while AnimatedSprite3D is preferred for more
+complex animations or when you need to manage multiple frames efficiently.
+
+This demo includes examples of basic rotation animation and showcases how
+shaders can be applied to Sprite3D and AnimatedSprite3D for stylized results.
+The shaders demostration also shows how to create paper-like effects, which can
+be useful for creating a unique visual style in most of the game.
