CTViewer-Research 0.3.3.3

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
