High quality renderer for pictures

[kheinz57]

Hi all. I am trying to build kind of a virtuell museum or call it 3d picture viewer. So you can walk or fly around and see paintings. Mainly as a learning project of Rust and bevy. And as an example to show art.
But the quality of the images seems to be pretty poor. Even when I come prettx close. Currently by using the bevy_flycam.
Would be nice to improve the quality or at least have to chance to switch to a complete 2d view.
Any ideas are welcome

Can you share a screenshot showing the quality issues? You'll probably want to generate mipmaps, use 16x anisotropic filtering, and set a bit of a negative mip bias.

Thanks for the answer. Since I am pretty new to the rendering and gaming stuff I have read more on your mentioned topics. It might as well be depending on tghe light. As of now I have only an ambient light in White with 0.8 brightness.
Here is the screenshot as coparison between left the bevy and right the oSX preview output.

The quality looks fine other than the brightness and contrast being off.

Set unlit to true on the material if you want to see the paintings as-is without any lighting applied.

You could also try placing a spotlight by the paintings.

Thanks, that solved it.
Spotlight was something I tried but still failed. Sounds like it will be in the end the better solution. But I guess when really zooming in on one painting te unlit seems like the best solution.
Will try to make the application at least a bit workig and will then publish on github. Since I now do have the confidence it will show the paintings correctly so I can preceed.

I have published it now. Very early version of course: https://github.com/kheinz57/theartgame
