Optix 6.0 Path Tracing demo

[jbikker]

Hi all,

Since the release of Optix 6.0 two days ago I have been playing a bit with the new RTX support. Here's a demo that should run on Maxwell, Pascal and Turing, which allows a direct comparison of the ray tracing performance of these platforms. Spoiler: Turing fares well.

New in version 0.3a:

- pre-RTX hardware will use a faster Optix Prime path (+~25%).
- TAA + sharpening for more temporal stability.
- A-Trous wavelet filtering for better performance (~25fps on 1060).
- Autonomous demo with spline path.

Instructions: toggle filter with F1, TAA with F2.

This is an 'under construction' demo which may or may not crash on your machine and so on. More updates will follow.

NOTE: this demo requires *very* recent drivers (like, about than a week old).

- Jacco.

Thanks for sharing.

Updated first post with new demo.

Would you mind if I used your version of the sponza model to test my own renderer?

The various open licensed versions I've found lack the detailing and have some questionable texture coords.

Also it's nice to be able to be able to compare exact scene rendering to an actual good renderer

Please go ahead. But I think this is straight from McGuire's page?
