Can't load 3D CT scan with odd size #414

Closed botanikas closed 1 year ago

botanikas commented 1 year ago

Can't load 3D CT scan. Program shows 100% status information and nothing going on. I have tried on several different PCs with different graphic cards and result is the same.

Desktop (please complete the following information):

OS: Windows 10 64bit
Weasis Version 4.1.0

Please activate the log files and transmit the result when loading the textures.

Some observations from the logs:

The graphics driver (27.20.100.9171) is not the latest version available (27.20.100.9664)
There are no errors when loading the volume
The images have an odd size (397x397) which is not common and I have already noticed that it sometimes causes problems. Can you try to force the subsampling by modifying the max size (X/Y) of the 3d texture? Set 256 (will decrease the rendering quality)

Changing 3d texture size to 256x256 solves the problem. GPU driver is lockdown to PC manufacturer and it is latest available. If I try to completely uninstall with DDU tool and than install latest from Intel, I get device not started in device manager event tab. Overall it's not related to GPU, because the same situation on others GPU's

I will try to reproduce the problem and see how it can be fixed

Speaking about image size, our CT scans from odontology clinic, so area of interest is quite small.
