Is this the first step toward building a viable holodeck?
No. Don't be fooled by the marketing. No one knows how to produce realistic-looking 100% CGI. Raytracing is even worse in some respects than traditional raster based graphics, and better in other respects.
Here's a heuristic that has never failed: If someone claims to have found a way to make photorealistic graphics, ignore them, because they're lying.
(This is true until it isn't, but at no point in history has it ever been true, yet. But that doesn't stop thousands of people and companies from claiming it.)
- mlindner 8y agoPure raytracing sure, but raytracing assisted by other methodologies can get you farther. Imagine doing low resolution ray tracing and then compositing that information with other rendering techniques. If you raytrace then interpolate you can get really really good.

- garmaine 8y agoPhoton mapping with physically based quantum BRDFs would be "realistic-looking 100% CGI." Because you'd be doing an exact physics-based simulation of electromagnetic light interacting with physically accurate materials. There's no way in hell you'd be able to do it real-time with models of sufficient detail though. So I presume you mean "... in realtime."
- mattnewport 8y agoThis hasn't been true for a while for certain applications under the right circumstances. There are architectural renderers, product renders and certain movie shots that will fool 99% of people into thinking they're looking at a photograph. Once motion is involved it gets much harder but there are still snippets of rendered video that could pass for real video. It is true however that the problem is not fully solved in general. There are still things that are not handled very well in still renders and animation (particularly human animation) breaks down in more situations.
