Is it possible vsg viewer's TransferTask support partial update image?

[simwangrui]

Hi,
I am using VSG developing my terrain based on geometry clipmap . It caches terrain geometry in a set of nested regular grids, which are incrementally shifted as the viewer moves.This means that the image is partially updated as the viewer moves.

I noticed that vsg viewer's TransferTask can help transfer images in the background.My current understanding is that TransferTask can only update the image as a whole,is it possible vsg viewer's TransferTask support partial update image?

Thanks

best wishes
