Content Development UnderTime Pressure

• A real-world example

Project Description

• Geospecific Database
• Remote part of the world
• How to determine architecture and cultural cues?
• Engaging Content
• Show off visual quality of Onyx
• Show special effects
• Representative architecture
• Short time schedule
• How to get from Maya - all- the - way - to -
  Performer

Example Case

• Image-based Geospecific Database
• Two different resolutions of imagery were
  available

5 meter / pixel
10 Miles
30 Miles
2 x 4 miles 1.25m/pixel
4
Problems with DEM

• Some type of wrapping error occurred
• Tested with multiple DBGS
• Lost much data if source was smoothed
• Used alternate DEM (backup)

5
High-res Imagery was good quality

• Individual buildings can be seen
• Major roads visible
• Registration perfect w/r/t background imagery

Overall Database View
7
_at_ Land

• Used 3D Studio Max
• Never again
• So we started over in Lightwave and Maya..

Lessons Learned

• Backup data sources are key
• Shift occurs between sources (DEM imagery)
• State-of-the-art process
• combines multiple DBGS tools
• Each doing their best feature
• You still usually have to write some code to do
  the job you want

13
We won the job, so then we had to do the real
thing...

Imagery Auto-Enhancement Algorithm

• Goal Enhance 1.25m/pix source imagery more
  quickly than by hand
• Reviewed potential processes in Photoshop
• Solution Source image is intensity modulated
  using a smoothed noise pattern

15
Auto-Enhancement Results

• Initial implementation used 4x up-sample
• Designed for site imagery preparation

16
Geospecific Site

• Size - 1000X1000 meters
• Geospecific culture
