Designing virtual conferences from the ground up using digital twins.

There's a massive matterport scan of a conference center in Munich, Germany that is freely available on the internet if you know where to look.

I've taken this scan to build a proof of concept workflow for planning, production, and archiving events that can take place in mixed reality.

We can streamline the event planning process by scanning the venue before something like a conference takes place. According to The VR Fund there already has been nearly 100 major VR/AR conferences and tradeshows this year (2018) and none of them have really utilized the power of the immersive web even though they all have websites.

Our ability to recall the value from the conference afterwords quickly gets diminished over time; many of the presentations and digital pictures/files get scattered into the winds of social media afterwords while conversations and business cards might lose their value in a week.

Here's a quick tour of the conference center scan, optimized after FireFoxG started 3D modeling parts of it:

The original conference scan was massive 528,000 triangles with 357 textures at 2k resolution. I was able to optimize it to ~402,000 triangles and 5 4k resolution textures.

The files were then handed over to Firefoxg who optimized the model even further down to 150,000 triangles with 4 4k resolution textures.

The biggest gains in optimization happened with the remodeling of the main speaker rooms which went from 202k triangles down to 33k.

All of the walls that were previously complicated meshes from the matterport scan have been flattened into quads, reducing the final triangle count from 528k to 25k.

When flattening the walls, there were some artifacts left in the scene when quads didn't quite line up. Using Vesta's positional comment system, it is simple to leave a comment for the 3D modeler to quickly teleport to and see what areas to focus on.

Planning Stage

The model and an html file with some janus markup was uploaded to a webserver so that we can view and edit the world online.
