Demo: Texture Sampling
=======================

The **Texture Sampling** preset showcases graphic transfer, UV projection stamping, and curved surface topology.

Overview & Architecture
-----------------------

* **Three Unique Target Geometries**:

  * **Top Screen**: Flat architectural display banner.
  * **Convex Canopy**: Radially curved outer cylinder shell.
  * **Bottom Cradle**: Smooth concave half-pipe.

* **Graphic Drivers**:

  * Animated driver planes carrying high-resolution textures (including the Blender logo and vibrant artwork).
  * As the textured drivers sweep across the curved and flat screens, the displays sample exact UV pixels at each contact ray, stamping colored artwork across the screens in real time.

Key Concepts Demonstrated
-------------------------

* **Curved Surface Raycasting**: Normal-oriented raycasting hugging both convex shells and concave bowls without artifacting.
* **High-Fidelity Color Sampling**: Direct pixel color transfer from image textures to emissive shader attributes.
