Both Unidirectional 3D Crystal Engraving and Omnidirectional 3D Crystal Engraving use 3D model files (like glb, obj, stl, gltf files, However, OBJ file is highly recommended). The main difference is the viewing effect and how the 3D information is processed.
Unidirectional 3D Crystal Engraving
Unidirectional 3D Crystal Engraving is optimized for viewing from a specific direction.
- The 3D model is processed based on a designated front-facing view.
- The front-facing side provides clearer details and more visible textures.
- When viewed from the front, the engraved image has higher detail and better texture quality.
- The effect may become less accurate or less detailed when viewed from other angles.
Best for:
- Detailed portraits
- Photos
- Models with important front-facing features
- Applications where the main viewing angle is fixed
Note:
Only supports textured 3D models. Models without textures will automatically use Omnidirectional 3D.
Omnidirectional 3D Crystal Engraving
Omnidirectional 3D Crystal Engraving is designed for multi-angle viewing.
- The 3D model is processed to maintain a complete 3D appearance from different viewing angles.
- The crystal can be rotated and viewed from multiple directions.
- The object looks more like a real 3D model inside the crystal.
- However, compared with Unidirectional engraving, surface textures and fine details may not appear as sharp.
Best for:
- 360° viewing models
- Sculptures
- Objects that need to be viewed from multiple angles
Key Difference
- Unidirectional 3D: Optimized for one viewing direction → sharper front-facing details and textures.
- Omnidirectional 3D: Optimized for multiple viewing directions → better overall 3D appearance from different angles.
