Hello,
We are trying to use the CameraUtilFraming to do crop region rendering (so having a certain portion of the viewport rendered with one renderer, with the rest rendered by another). For this we are currently experimenting with the CameraUtilFraming API, which allows us to define a region of pixels (dataWindow) for the renderer to fill.
However, we are unsure of what kind of data to expect for pixels outside the dataWindow. Is it expected that they are empty/cleared, or is it undefined and they might contain outdated data/data from previous renders?
This would impact how we are able to do the composition of the renders obtained from rendering the crop region and the base scene render (e.g. if data outside the crop region is expected to be cleared, we could compose the two renders as-is, otherwise we might need to do extra operations).
Thanks!
Philippe
