|
+ OBJECT MANIPULATION
|
|
|
+****************************************************************************
|
|
|
+
|
|
|
+All object manipulation is performed with left mouse button (LMB).
|
|
|
+Object's are selected by clicking on the with the LMB. Objects
|
|
|
+can be manipulated freely, or manipulation can be constrained using DIRECT
|
|
|
+widgets. Rotations and scales are relative to the object's Center of
|
|
|
+Action (COA). If widget is made visible ('v' key), this is the point of
|
|
|
+intersection of the three axes (red,green,blue lines).
|
|
|
+
|
|
|
+FREE MANIPULATION:
|
|
|
+For free manipulation, the window is divided up into three regions: an
|
|
|
+outer frame, central region, and the four corners. Object manipulation
|
|
|
+depends on where mouse interaction begins.
|
|
|
+
|
|
|
+Central Region:
|
|
|
+ LMB:
|
|
|
+ Up/Down/Left/Right: Moves object in plane parallel to camera's image
|
|
|
+ plane
|
|
|
+ Shift + LMB:
|
|
|
+ Up/Down: Moves object's COA towards camera
|
|
|
+ Left/Right: Moves object parallel to camera's X axis
|
|
|
+ Alt + LMB (off of widget):
|
|
|
+ Away from COA: scale object up
|
|
|
+ Towards COA: scale object down
|
|
|
+Outer Region:
|
|
|
+ LMB:
|
|
|
+ Up/Down/Left/Right: Rotates object about current COA (default is
|
|
|
+ model's origin, modified using manipulation widget...see below).
|
|
|
+ If mouse stays within outer frame, motion about COA is constrained
|
|
|
+ to a single axis. (parallel to camera's X axis when in left and
|
|
|
+ right part of the frame and parallel to the camera's Z axis when
|
|
|
+ in the top or bottom part of the frame)
|
|
|
+Four corners:
|
|
|
+ LMB:
|
|
|
+ Up/Down/Left/Right: Roll object about current center of action.
|
|
|
+
|
|
|
+CONSTRAINED/WIDGET MANIPULATION:
|
|
|
+For constrained/widget manipulation, object motion depends on where the
|
|
|
+mouse begins:
|
|
|
+ Axis lines: 1D translation along the chosen axis
|
|
|
+ Rotation rings: 1D rotation about orthogonal axis
|
|
|
+ Translation discs: 2D translation in the plane of the disc
|
|
|
+
|
|
|
+Pressing 'Tab' toggles between object manipulation or COA manipulation
|
|
|
+(indictated by widget lines turning grey). When in COA manipulation mode,
|
|
|
+movement of the widget does not move the object but changes the object's
|
|
|
+COA. Hit 'Tab' again to return to normal object manipulation mode.

+ CAMERA MANIPULATION
|
|
|
+****************************************************************************
|
|
|
+
|
|
|
+All camera manipulation performed with middle mouse button (MMB).
|
|
|
+
|
|
|
+Window is divided up into three regions: an outer frame, central region, and
|
|
|
+the four corners. Camera manipulation depends on where mouse interaction
|
|
|
+begins.
|
|
|
+
|
|
|
+Central Region:
|
|
|
+ MMB:
|
|
|
+ Up/Down: Moves camera towards mouse intersection point
|
|
|
+ Left/Right: Yaws camera
|
|
|
+ Control + MMB:
|
|
|
+ Up/Down: Moves camera along view vector (perpendicular to image plane)
|
|
|
+ Left/Right: Yaws camera
|
|
|
+ Shift + MMB:
|
|
|
+ Up/Down/Left/Right: shifts camera in image plane
|
|
|
+Outer Region:
|
|
|
+ MMB:
|
|
|
+ Up/Down/Left/Right: Rotates about current COA. The COA is set every
|
|
|
+ time you press the MMB in the central region. It is defined as the
|
|
|
+ intersection point of the ray from the camera's origin, through
|
|
|
+ the mouse with the model (if no intersection, no change in the COA
|
|
|
+ will result). If mouse stays within outer frame, motion about COA
|
|
|
+ is constrained to a single axis. (parallel to camera's X axis when
|
|
|
+ in left and right part of the frame and parallel to the camera's Z
|
|
|
+ axis when in the top or bottom part of the frame)
|
|
|
+ Shift MMB:
|
|
|
+ Up/Down: Pitch about camera's X axis
|
|
|
+ Left/Right: Yaw about camera's Z axis
|
|
|
+Four corners:
|
|
|
+ MMB:
|
|
|
+ Up/Down/Left/Right: Roll about current center of action.
|
|
|
+
|
|
|
+The number keys and plus minus keys can be used for motion relative to the
|
|
|
+COA (see hot keys below)
