bug when zooming in with mouse wheel #55

Open tischi opened 7 years ago

tischi commented 7 years ago

Hello, when we zoom in and out we sometimes get a smear in the data (see attached "artifact" image). Are you aware of this issue?

Hey @tischi, thanks for your report! I have not seen this (up to now :-D). So it happens everytime you scroll, or only under certain conditions? What is your hardware configuration and what OS are you using?

Hey!

The specs are from a comp of one of our users: image

Hi Tischi,

To solve the issue, press key ‘m’, this will deactivate the multi-pass rendering algorithm. The multi-pass algorithm speeds up rendering but it seems that there is a multi-threading problem and sometimes the clearing of the buffer is not performed when the view is changed, leading to the effect you noticed…

With Ulrik we are working on ClearVolume 2.0, will take some time as it is a full redesign, hopefully we can iron out some lingering bugs.

sorry for that!

Loic

Great! Thank you for the information! In fact, the bug did not really bother me, I just thought it is good community practice to report it anyway, in order to make your software even more awesome!
