Khronos glTF 2.0

glTF 2.0 is Khronos's open format for delivering 3D models and scenes to applications and viewers. Its material model and compact asset structure suit product visualisation, including footwear and digital garments prepared for ecommerce. Files can use JSON with separate resources or the binary GLB container. For a brand, glTF belongs near the customer-facing end of a 3D workflow: it leaves out authoring information to reduce runtime work, so a delivery asset should not be the only design archive. Material extensions can describe further surface properties. Review the asset in the intended viewer with its actual lighting before approving the appearance of a fabric or finish.

What to check

  • A GLB can still reference external resources. Check dependencies before calling a file self-contained.
  • Inspect extensionsUsed and extensionsRequired, then confirm that the target viewer supports them.
  • Pair Khronos validation with visual review. A structurally valid asset can still look different across renderers.
