Technical note

What changes when you convert VSI to GLB

VSI is made of pixels and GLB 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 GLB container.

I needed to convert my pathology slides (VSI format) to standard images for a research paper. reaConverter handled this smoothly - it's much faster than the default Olympus software and maintains decent image quality. The batch processing saved me hours of work.
