Command line options:
To start program, use ct_viewer.
Can enter debug mode with -debug
Select GPU with -gpu=<device number>
Default is -gpu=0
Config file:
A configuration file will now be created/loaded at $USERHOME/.config/ct_viewer/config.ini
Geometry:
All files are loaded in and interpolated to be 1 x 1 x 1 mm/pix using the pixel dimensions, slice thickness, and volume affine.
They are initially centered at (0, 0, 0) in physical space in mm.
If no affine is present, assumes a 1x1x1 mm^3 voxel dimension and positively aligned volume.
Navigation:
All navigation is done from the perspective of the patient according to the affine
of the volume.
a - Move volume in the negative X direction - Patient moves to their Right
d - Move volume in the positive X direction - Patient moves to their Left
w - Move volume in the negative Y direction - Patient moves to their Anterior
s - Move volume in the positive Y direction - Patient moves to their Posterior
q - Move volume in the negative Z direction - Patient moves to their Inferior
e - Move volume in the positive Z direction - Patient moves to their Superior
z - Negative change in image index -
c - Positive change in image index -
Shift + a - Negative pitch of volume - Rotates about X, moves Z into Y.
Shift + d - Positive pitch of volume - Rotates about X, moves Y into Z.
Shift + w - Negative yaw of volume - Rotates about Y, moves Z into X.
Shift + s - Positive yaw of volume - Rotates about Y, moves X into Z.
Shift + q - Negative roll of volume - Rotates about Z, moves Y into X.
Shift + e - Positive roll of volume - Rotates about Z, moves X into Y.
Shift + z - Swaps between Group and Local control -
Shift + c - Swaps between Group and Local control -
Alt + a - Negative zoom in X direction -
Alt + d - Positive zoom in X direction -
Alt + w - Negative zoom in Y direction -
Alt + s - Positive zoom in Y direction -
Alt + q - Negative zoom in Z direction -
Alt + e - Positive zoom in Z direction -
Crtl + Any - Changes navigation setting at 5x the current increment.
- Does not effect z and c keys.
Middle Mouse - Click and drag to move the volume. Currently a little floaty as the rendering and mouse motion aren't perfectly aligned.
Spacebar - Create landmark at crosshair position
