This 3D model, titled Regal Adornment: A Jewel-Encrusted Ceremonial Crown, is a highly detailed digital representation of a traditional sovereign's crown. It features an intricate design with ornate details and is adorned with a variety of gemstones including rubies, sapphires, emeralds, and diamonds, all of which are meticulously modeled for a realistic appearance.

The model is available in multiple file formats to ensure compatibility with a broad range of 3D software and applications:

FBX (.fbx): A flexible and widely-used format, ideal for inter-application use and supported by most 3D graphics applications.

OBJ (.obj): A geometry-definition file format that encapsulates precise details about the model's geometry and is easily imported into various 3D graphics programs.

GLB (.glb): The binary version of the GL Transmission Format, optimized for web applications and virtual reality platforms.

USDZ (.usdz): A file format developed by Apple and Pixar for sharing 3D graphics and is used for augmented reality experiences on iOS devices.

Blender (.blend): The native file format for Blender, a free and open-source 3D creation suite, containing all the data for the model including textures, lighting, and animation.

STL (.stl): Widely used for 3D printing and computer-aided manufacturing, focusing mainly on the surface geometry of the crown.

Each format of the crown model is designed to maintain the integrity of the mesh and the clarity of textures, ensuring that the digital artifact can be utilized for various purposes such as animation, game development, VR/AR experiences, and 3D printing.
