The following comes from a September 6 OC Catholic article:

The Diocese of Orange will celebrate its 40-year history on Sept. 18 with an entire day of activities that begin first thing in the morning with a 5k race, and end late in the evening with a much-anticipated concert. While the last four decades will be commemorated, the real focus of the celebration will be on the future.

A very special virtual reality event that day will allow congregants to get a glimpse of the fully renovated Christ Cathedral, two years before its scheduled completion.

Using hi-tech virtual reality equipment and complex software the public will be able to tour the interior of the cathedral as it will look when completed, all while sitting within the existing still-under-construction cathedral space.

Ryan Lilyengren, director of communications for the Diocese of Orange, said, “We may be the first Catholic Diocese to introduce a new cathedral by inviting congregants and media into a virtual reality experience.” He added, “The fully immersive program will be a breakthrough for Church communications and further evidence of how the Diocese cherishes its past, but is clearly focused on the future.”

All who attend the anniversary celebration on Sept. 18 on the campus of Christ Cathedral will be able to share in the experience. It will be presented in a 3D format that will be mobile-device enabled, permitting thousands of regional Catholics their first glimpse of the future cathedral.
