The demo result doesn't look so good as the result in paper?

[xiehousen]

I run the data set of sample provided by download_replica_sample.bash, which is the display effect. From this result, it seems that the effect is not as good as that in the paper. Need to change some parameters?

PS: WARNING Could not initialize Vulkan and NGX. DLSS not supported.

Hi @xiehousen. Could you please show me how to get that result? I even cannot get anything.

In fact, I don't know how to compile to display. You may need to replace an instant ngp and gtsam version.

In addition, I will display many flags when running. But I don't know whether it is right to output these things.

I can't see anything in the result

The eval result (PSNR, L1) is zero.

The eval result (PSNR, L1) is zero.

Same as my case. That's why the output result of GUI is as my aforementioned figure. I wonder what's wrong with this code? @ToniRV @jrpowers

I got the same problem before and solved it by installing Vulkan SDK and enabling DLSS.

• Install Vulkan SDK: https://vulkan.lunarg.com/doc/view/latest/linux/getting_started_ubuntu.html
• Enable DLSS: https://github.com/NVlabs/instant-ngp/issues/621#issuecomment-1133095007

Then compile instant-ngp.
