Raytracing is sort of like nuclear fusion: a few years away for my entire life. Not clear what changed yet.

Well I imagine today’s GPU would be more than capable of doing an amazing looking game at 320x240 or maybe 640x480 at a reasonable frame rate.

The problem is at this point people want it at 1080, 4k or 8k.

Earlier quoted context omitted.

In path tracing ( https://en.wikipedia.org/wiki/Path_tracing ), which is what the VFX industry uses primarily, both directions happen.

Does anyone use path tracing for live renderings? I think that is the question.

Brigade Engine, for example: https://home.otoy.com/render/brigade/

I'm pleased to see that the tech video includes spherical mirrors. As I understand it, all raytracing demos are obliged by universal law to include at least three reflective balls in any promotion of the technology.

One day, someone will figure out a game where these super-shiny ball bearings are a critical part of the gameplay, and at that point, raytracing will finally take off...

I can't help but imagine the massively power-hungry machines hosting the GPUs necessary for real-time rendering of Pixar-level movie graphics.

Won't this resemble power demands of crytpocurrency mining rigs except actually used for gaming? As if it weren't already bad enough the amount of energy we use per capita...

can this somehow work with autocad, etc so that construction fragments could be previewed in real time with Raytracing and global illumination turned on?

"CAD"-like programs from the animation and VFX worlds (Houdini, Modo, etc) already do this, so if Autodesk really wanted to they could almost certainly add real-time path tracing to AutoCAD.

In my experience with blender, though you can create very detailed photo realistic images without raytracing, but using raytracing makes it much easier to make the same photos. It takes longer, but it's probably the direction we're going generally with 3d rendering given Moore's law.

Anyway this seems a little overhyped
