Ive been trying to create a shadow behind a sphere in a GUI. However, it keeps giving me an error when I put in shadowplot x. I do not know if there is a better way to do this for a sphere.
This is the error i keep getting. "Surface must have at least 2 monotonically increasing dimensions"
If anyone knows the best way to use the shadowplot command specifically for a sphere i would greately appreciate it.

While "shadowplot" (SHADOWPLOT - File Exchange - MATLAB Central (mathworks.com)) isn't ideal for spheres in GUIs, here are effective methods:
  1. Patch Object: Create a slightly larger, semi-transparent dark patch positioned behind the sphere for a shadow effect. Customize its size, color, and transparency in your GUI.
  2. Lighting and Material: Use lighting ("light") and material ("material") properties for more control over the shadow's appearance and realism.
  3. Image Overlay: Pre-render a shadow image (e.g., dark circle with transparency) and overlay it behind the sphere.
Choose the method that best suits your needs for simplicity, control, or performance. Utilize UI elements for precise positioning within the GUI.
