FAQ
HDRI to U3D Conversion
What are HDRI files?
SilverFast’s 64-bit HDRi RAW file is a TIFF that preserves a full 16-bit-per-channel RGB scan plus a separate 16-bit infra-red channel, giving 64 bits per pixel. The visible data stays completely unprocessed—no sharpening, gamma, or colour tweaks—while the IR map lets SilverFast’s iSRD (or compatible tools) later remove dust and scratches non-destructively, making it an ideal “digital negative” for archival film workflows.
What are U3D files?
U3D (Universal 3D) is a standardized file format used to store and exchange 3D models and scenes. It supports geometry, textures, colors, lighting, and animations, allowing complex 3D content to be represented efficiently. U3D is best known for its use in interactive PDF documents, where users can rotate, zoom, and explore embedded 3D models. The format is widely used in engineering, architecture, manufacturing, medical imaging, and scientific visualization.
