Technical note

How ETS and GLTF differ in practice

ETS is made of pixels and GLTF is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a GLTF container.

FAQ

ETS to GLTF Conversion

What are ETS files?

ETS files are used in virtual microscopy to store the full-resolution image data captured from digital slides. Commonly generated by Olympus slide scanners, ETS files work alongside VSI (Virtual Slide Image) files to enable detailed, zoomable viewing of high-resolution microscope images. An ETS file contains the raw image tiles that make up the actual slide content, allowing for fast, fluid navigation across large specimens in digital pathology and biomedical research.

What are GLTF files?

glTF or GL Transmission Format is a vector extension developed by the non-profit consortium Khronos with the aim of improving interoperability between various types of software specialized in creating and accessing 3D content.
