Spatial Standards
A way to define the space in such a way that software could be added as a plug and play.
This is a function of the software and providing a common definition of the physical space.
![Page 5: Developing a Fulldome Standard: A Historical Perspective for Success](https://reader035.vdocuments.net/reader035/viewer/2022062409/568147f1550346895db52a3c/html5/thumbnails/5.jpg)
Problems of Definition
Create a physical space and map a virtual space to it
-where is 0,0,0?
-what is the unit of measure

Test Patterns
Centered on a physical location
-CAVE test patterns moved from center of the cave to center of the floor
Multiple test patterns to perform multiple functions
→ Alignment (CRT only?)
→ Scaled registration
→ Sub system test patterns (audience response, navigation, tracking)
→ Residual Error (specific for a projector / bend system)
→ Black Balance / Color balance
→ Users guide with test patterns so that non-engineers can correctly define issues

Standards
It is very easy to have a technical success and a market failure.
If the standard is not supported it doesn’t matter.

“Symbiosis is not working well, but there is no reason for this other than the lack of industry standards. The viewing public would be best served, and so would industry, if greater efforts were made to respond to our needs.”
“The one area of this institution that does not need biodiversity is the technology”
“Exchange of knowledge, means exchange of content.”
