March’s game developer conference is undoubtedly the focus of ray tracing, but now it looks like there are other things that are worth paying attention to, but are ignored by us.
Although during the conference we can see the schedule of 'Real-Time Voxel-Based GI' and 'Temporal Super-Resolution', we didn't think too much at that time. Until last night, WccfTech got a demonstration of VXGI 2.0 in the speech at that time. Documentation, only to find that the original technology has been upgraded to version 2.0.
Although I don’t know if it’s rigorous, we Generally, when reporting, translate 'VXGI' and 'VXAO' into 'volume-pixel global illumination', 'volume-pixel ambient light' They are new technologies that come with Maxwell architecture, but in fact we don't see much in the game.
With the exception of Tomb Raider: Rising, Final Fantasy XV Windows Edition is used to the latter, it can provide a deeper, more spatial sense of environmental shadows. Of course, the hardware requirements are even more common than our common HBAO+. .
The presenter who introduced VXGI 2.0 in this game developer conference is actually Alexey Panteleev. The new version of VXGI 2.0 was first introduced to improve the effect of High Quality Area Lights, mainly to support more. Multiple Area Lights, textured rough surface or color, dynamic material.
At the same time, there is One-Pass Voxelization that can bring the CPU and GPU performance to double. In the previous VXGI 1.0, not only was the performance lower, but also in the opacity, the radioactivity was independent, and now it is obviously belonged to 'One-Pass'. Of course, these are things that developers will know, and for me, games that support VXGI 2.0 effects (if supported) will be relatively more friendly to hardware.
However, in this presentation, the content of hardware support is not explained, so it is not easy to guess whether VXGI 2.0 will be limited to the new architecture hardware if it is applied to the consumer in the near future.
