Exploring the museum
An inadequate substitute
Solution? An interactive panorama

Additional context
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
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
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
Process for creating a panorama
1. Take pictures 2. Merge HDR (optional) 3. Stitch panorama 4. Convert to cubic 5. Put in x3d
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
HDR
� High dynamic range ¡ Multiple exposures merged later ¡ Lossless format, not JPEG ¡ Even cheap smartphones have this capability
Middle exposure
Low exposure
High exposure
Merged
Stitched panorama
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
