The operator update_window_poseupdate_window_poseUpdateWindowPoseupdate_window_poseUpdateWindowPoseUpdateWindowPose provides an easy way to modify the
pose of the height field displayed by disp_objdisp_objDispObjdisp_objDispObjDispObj if the paint mode is
set to '3d_plot'"3d_plot""3d_plot""3d_plot""3d_plot""3d_plot" using set_paintset_paintSetPaintset_paintSetPaintSetPaint.
Two window coordinates (LastRowLastRowLastRowLastRowLastRowlastRow,LastColLastColLastColLastColLastCollastCol) and
(CurrentRowCurrentRowCurrentRowCurrentRowCurrentRowcurrentRow, CurrentColCurrentColCurrentColCurrentColCurrentColcurrentCol) are transformed into rotation,
scaling, or movement depending on ModeModeModeModeModemode.
This window coordinates must be provided with respect to the current image
part. As a consequence, this coordinates are subpixel coordinates. Given the
current image part (row1,column1,row2,column2), the upper left
corner corresponds to the coordinate (row1 - 0.5, col1 - 0.5). Accordingly,
the bottom right corner corresponds to the coordinate
(row2 - 0.5, col2 - 0.5). Use get_mposition_sub_pixget_mposition_sub_pixGetMpositionSubPixget_mposition_sub_pixGetMpositionSubPixGetMpositionSubPix or
get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPix to obtain this coordinates directly.
If ModeModeModeModeModemode is set to 'rotate'"rotate""rotate""rotate""rotate""rotate", the height field is rotated
using a virtual trackball model. Both points are projected on a sphere
centered in the center of the window WindowHandleWindowHandleWindowHandleWindowHandleWindowHandlewindowHandle. The circular
arc between this two projections corresponds to the rotation applied
to the height field.
If ModeModeModeModeModemode is set to 'scale'"scale""scale""scale""scale""scale", zooming is reduced if
CurrentRowCurrentRowCurrentRowCurrentRowCurrentRowcurrentRow is greater than LastRowLastRowLastRowLastRowLastRowlastRow and increased if
CurrentRowCurrentRowCurrentRowCurrentRowCurrentRowcurrentRow is smaller than LastRowLastRowLastRowLastRowLastRowlastRow.
If ModeModeModeModeModemode is set to 'move'"move""move""move""move""move", the input points are projected
onto the plane through the center of the height field parallel to the viewing
plane. The center of the height field is moved in this plane by the distance
between both projections.
If ModeModeModeModeModemode is set to 'move_plane'"move_plane""move_plane""move_plane""move_plane""move_plane", the input points are
projected on the plane given by height zero. The height field is moved in
this plane by the distance between both projections.
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Processed without parallelization.
