Replicate SEM views using microCT data + VisIt VR #33
Description
@wmondy has taken a number of Scanning Electron Microscopic (SEM) images of the same specimen.
It would be good to try to duplicate (as much as possible) those views with the microCT data using VisIt volume rendering.
There are several things to try to get right...
- Color map. SEM images are all gray scale.
- Camera parameters (position, direction of view, focal point, depth of field, etc.)
- Resolution
- SEM images are quite high resolution.
- There are resolution annotations (over 100 pixels in length) to indicate a length and its absolute spatial distance.
- In example here, the annotation is 137 pixels indicating 200 micrometers. This means each pixel is ~1.46 micrometers. That is about 6.85x better than the microCT data at 10 micrometers per pixel. In the same image, below, I have reduced the resolution by a factor of 6.85...
