Implement progressive multi-frame rendering #3361

Open mvaligursky opened 3 years ago

mvaligursky commented 3 years ago

The algorithm is described in GPU Pro 7, chapter 3.1

It allows for image quality to improve when the camera is static (and the scene is not animated) by accumulation of slightly shifted frames. This generates high quality antialiasing (TAA), and can also be used to generate soft shadows. All this without requiring (many) additional resources.

Additionally, we could possibly add support for progressive scaling here .. rendering the scene in lower resolution when the camera moves to keep the performance higher, and use full resolution when the camera stops.

Just wonder when this feature is going to be added.

mvaligursky commented 2 years ago

There are no immediate plans to work on it, unless somebody wants to help.

I believe this is quite important issue for most of users who is using Playcanvas as industrial purpose. Hope it will be added soon. 🙂

It would be great to have the work that was done for the Model Viewer rendering as a drop in Editor script
