Basic SUMA viewer functions• Rotating the surface:★ Mouse button-1: keep it down while moving the mouse left toright. This rotates the surface about the screen's Y-axis (dottedgreen). Let go of button-1 (usually the left button).★ Repeat with up and down motion for rotation about X-axis andmotion in various directions for rotations mimicking those of atrackball interface.★ Also try up/down/left/right ↑ ↓ ← → arrow keys.➥ Arrow keys rotate by increments specified by the Unixenvironment variable: SUMA_ArrowRotAngle (degrees).➥ You can set SUMA environment variables in file ~/.sumarcHands-On29 Oct 2009 SSCC/NIMH 14
Basic SUMA viewer functions• Prying & Z rotating the hemispheres:★ Mouse ctrl+button-1: Moving the mouse horizontally whilebutton 1 is pressed and ctrl is down will pry hemispheres apartfor better visualization. The prying behavior is different forspherical and flattened surfaces. Better try it than read about it.★ Ctrl+button 1 doubleclick: Undo prying.★ Mouse shift+button-1: Rotate surfaces about screen’s Z-axis.This option is useful for positioning flat surfaces when displayedone at at time. In most other circumstances it leads toconfusion.★ Shift+button 1 doubleclick: Undo Z rotationHands-On29 Oct 2009 SSCC/NIMH 15
