The document describes how to create an interactive panoramic experience using X3D to allow virtual exploration of a physical space. It outlines the process of taking panoramic photos, stitching them into a panorama, converting the panorama to a cubic format, and embedding it in an X3D file to create an immersive digital experience. The goal is to provide access to physical spaces that may be difficult to visit in person.

- 9. X3D panoramas Easily take a physical space and create an interactive, immersive digital version that allows those unable to visit in person a chance to explore the space and provide additional context
- 10. What is X3D “X3D is a royalty-free open standards file format and run-time architecture to represent and communicate 3D scenes and objects using XML. It is an ISO-ratified standard that provides a system for the storage, retrieval and playback of real time graphics content embedded in applications, all within an open architecture to support a wide array of domains and user scenarios.” -- What is X3D X3DOM is a Javascript implementation of X3D
- 11. Why X3D? — ...over other technologies like Flash, WebGL, Unity, etc. — Open, royalty-free, ISO standard dating back over 20 years ¡ 1994 – VRML1 – static models only ¡ 1997 – VRML2/VRML97 – moving/interactive worlds ¡ 1999 – X3D – eXtensible, XML encoding, modular profiles, v.3.3 in Nov. 2013 — High-level, declarative scene description (not imperative programming) — Encapsulates best thinking and practices from 3D graphics community — Content sustainability ¡ Human-readable ASCII plus efficient Binary encodings ¡ Widely supported as a static file format and interchange format ¡ Several open-source and commercial X3D viewer implementations — X3DOM ¡ open-source JavaScript implementation ¡ HTML5 DOM model – no plugin required
- 12. Process for creating a panorama 1. Take pictures 2. Merge HDR (optional) 3. Stitch panorama 4. Convert to cubic 5. Put in x3d
- 13. Panoramic photography — Any photo taking device can be used to take a panoramic photograph – quality is the issue — Cell phone — Rico Theta — DSLR camera — Gigapan
- 14. HDR — High dynamic range ¡ Multiple exposures merged later ¡ Lossless format, not JPEG ¡ Even cheap smartphones have this capability
- 15. Middle exposure
- 16. Low exposure
- 17. High exposure
- 18. Merged
- 20. Panoramas in x3d — You’ll have a mirrored view, flip your image. — Individual textures limited to ~16 million pixels (4096x4096) — For higher quality split your sphere into a cube Saladoconverter https://github.com/mstandio/SaladoConverter/downloads The ceiling and floor often can be low quality Individual cube faces can be further divided for even higher quality
