This video is not that fresh. I have seen it already last year and the way how this guys speaks has not changed since then (speaks like a salesmen) ;)

Their technique is based on point cloud rendering. My supervisor has proposed already in 2004 how this can be done on a standard PC. Look at his PhD-Thesis [1].

This technique is usable for static objects as well as for dynamic objects; however, using it for dynamic scenes additional acceleration structures are required (besides of the Octrees) in order to dynamically change according to the deformation of the object. To clarify on several comments made here:

- this is a rasterization technique

- they used acceleration data-structures like Octrees, kd-trees, BVH, ... (which exactly they don't tell)

- the graphic "aesthetics" depends actually only on the artists and not on the technology itself, so not a good point

+1. I'd actually trust the company more if they had someone who spoke in measured tones and laid off the hyperbole.

But did your supervisor ever ship a product that did it?

[cgart]

Yes. We use his original software, XGRT, every day in our research group. All our research about point clouds and geometry is implemented as modules in this software. The software is open source and supports point clouds of really huge sizes, e.g. 80GB datasets, dynamically streamed from the disk.
