He literally came up with the idea almost 10 years ago and at the time said the hardware required to make the move didn't exist yet.
But anyway, the octree would be to optimize storage and processing for both sets of data: the virtual textures and the virtual geometry.
Isn't one of the reasons as to why Project Offset was cancelled is because of the failure to implement real-time ray tracing?
Only thanks to Amazon buying their engine.
It has nothing to do with gaming for one thing, it's a marketing term for high memory bandwidth coprocessor cards that they've been developing for the last decade to sell to organizations that buy tens of thousands of highend GPUs at a time for their supercomputers.
This is the newer Sierra computer with 17,280 GPUs, the one before it had 27,600 GPUs.
These massive computers being built at an unprecedented rate are the reason for the high price of GPUs and DDR4 memory, both of which share almost identical price hikes in the last few years. The consumer GPUs getting bought for cryptomining is just a small portion of the problem.
I think it's actually extremely difficult to fail making a real-time ray tracing renderer. It's just that for last 2-3 decades it has always been way too computationally expensive. That's for sure one of the reasons Carmack said back in 2008 the hardware didn't exist yet.
Intel's Knights Ferry or something based off that R&D was looking very promising for real time ray tracing, but they spun it into a non-graphics processor addon or something I forget.
Are you serious?!
Do go on I'm interested in hearing more.
That's actually a load of bullshit that everyone who has passed econ 101 can see plainly. You might as well claim that IBM's z13/z14 are the reason Intel i-series costs are higher too.
proprietary fixed function GPGPU-CPU hybrid hardware (not a GPU!) that Intel thought could compete against the entire graphics industry
circular internal politics and delays with the complicated specifications killed it after it no longer was viable as regular consumer product
I hope this Ray Tracing tech wont make the same mistakes
Ironically it already has.
Whatever the future of Intel's Knights Ferry holds, it certainly still has real time ray tracing in its grasp above all other "competitors".

I know these are pathtracers, but still interesting. I don't really know the difference between this and raytracing.
