About TVglyphView

Basic Usage Pattern

which displays an axial view of the tensor image.

The following list of the available keystroke controls can be printed using 'H'

• 'a'|'A': rotate out-of-plane 5 degrees counterclockwise|clockwise
• 'f'|'F': increase|decrease ellipsoid scaling factor
• 'r': reset to original view
• 's'|'S': rotate in-plane 5 degrees counterclockwise|clockwise
• 'x': flip left and right
• 'y': flip up and down
• ','|'.': go to the slice below|above
• 'j'|'k': shift the view to left|right
• 'h'|'l': shift the view up|down
• 'p': save the current rendering in a png file
• '1': toggle the visibility of the tensor glyphs
• '2': toggle the visibility of the background or overlay if supplied
• '3': toggle the visibility of the outline
• '4': toggle the visibility of the red arrow
• '5': toggle the visibility of the green arrow
• '6': toggle the visibility of the blue arrow

MUST READ: One of the most useful features is the ability to scroll through the slices. However, because the 3D visualization is a computational intensive operation, it is recommended to toggle the visibility of the tensor glyphs to off when you need to scroll to a different slice. Then toggle the visibility back on when you get to the slice you'd like to visualize with the tensor glyphs.

In order to adjust the visualization of your image, here are all the options available for the usage of TVglyphView
