GUI works, but not show image #207

Closed ShunFurui closed 2 years ago

ShunFurui commented 2 years ago

Hi, I am trying this nice library.

When I run GUI like

./build/testbed --scene data/nerf/fox

screen is black in the first a few seconds and then the fox keeps disappearing and reappearing. And after I click "Stop Training", fox disappear and never appear again. When I click "Mesh It!" in "Marching Cubes Mesh Output", screen shows mesh of fox. When I see box in GUI, it says "Frame 70.***ms" and "Render 70ms". There is no error in command line.

I think training is working well but rendering image is not working correctly.

Is there a button to be clicked to show rendered image? I am using RTX3080, is there a problem of computational cost?

After I reinstalled everything, this problem is solved. What I changed is installing OptiX, but cmake didn't find it. So I don't know what was direct reason, but works good. I close this issue.
