The general idea is:
- try to solve it with callbacks
- if something is in your way to be able to solve it with callbacks, please discuss specifics and we can discuss modifying backend accordingly.
from imgui.
This is a topic that applies to every backends.
Generally the suggested solution (e.g. #3590) is to use a AddCallback()
drawcmd to manually make the render change sampler or other render state. Note how e.g. #7511 or #6908 would lead to same direction.
Now, whether this is easy or even possible might depends on the backend and how to alter that render state.
For some backends user code may lack access to backend internal data and we may need a solution for that.
I think you should dig in WGPU backend and see if you can find a way to implement this via draw callbacks.
Generally I think we ought to find solution to make some common case easier (e.g. switch from linear to point filtering).
#2697 essentially proposed making user able to rewire texture binding code while using standard backends which is probably a desirable eventually but would drag a bunch of other things, as user code may need more standardized access to some backend internal data.

Thanks for the clarification. I agree this not might be easy since problem is tricky to solve in a backend agnostic way which is case for WebGPU too due to lack of api to determine texture state after creation but I will look draw callbacks and what can I do. I close this issue due to there is already plenty of discussions about similar points.
