Glossary
B
- BVS. Bond Valence Sum. An empirical method in crystallography and coordination chemistry used to estimate the oxidation states of atoms based on observed bond lengths. shapeXT supports numerical approaches by Brown (1985) and O'Keeffe (1991), as well as calculations utilizing tabulated reference parameters (as provided on the IUCr website).
C
- COD. Crystallography Open Database. An open-access collection of crystal structures of organic, inorganic, metal-organic compounds, and minerals. shapeXT allows users to fetch and visualize structures directly from this database using a 7-digit ID.
G
- GPU. Graphics processing unit.
M
- MoltenVK. A software translation layer that maps Vulkan API calls to Apple's Metal graphics framework. shapeXT relies on MoltenVK to bring its Vulkan renderer seamlessly to macOS and Apple Silicon hardware.
S
- SPIR-V. SPIR-V™ is a registered trademark of the Khronos Group Inc.
V
- Vulkan. Vulkan® is a new-generation graphics and compute API for high-efficiency, cross-platform access to GPUs. Vulkan and the Vulkan logo are registered trademarks of the Khronos Group Inc.
