Description
get_display_scene_3d_infoget_display_scene_3d_infoGetDisplayScene3dInfoGetDisplayScene3dInfoGetDisplayScene3dInfo returns information on the
3D object models in the 3D scene Scene3DScene3DScene3DScene3Dscene3D that have been displayed
with display_scene_3ddisplay_scene_3dDisplayScene3dDisplayScene3dDisplayScene3d in the window WindowHandleWindowHandleWindowHandleWindowHandlewindowHandle.
The requested information at the positions (RowRowRowRowrow, ColumnColumnColumnColumncolumn)
is returned in ValueValueValueValuevalue.
The following values can be queried via InformationInformationInformationInformationinformation:
- 'object_index'"object_index""object_index""object_index""object_index"
-
The indices of the 3D object models that have been displayed at the
positions (RowRowRowRowrow, ColumnColumnColumnColumncolumn).
If no 3D object model was displayed at this position, -1 is returned.
In order to retrieve this information, the parameter
'object_index_persistence'"object_index_persistence""object_index_persistence""object_index_persistence""object_index_persistence" must have been set to 'true'"true""true""true""true"
with set_scene_3d_paramset_scene_3d_paramSetScene3dParamSetScene3dParamSetScene3dParam.
- 'depth'"depth""depth""depth""depth"
-
The depth (i.e. the Z coordinate in the camera coordinate system) at the
positions (RowRowRowRowrow, ColumnColumnColumnColumncolumn). If no 3D object
model was displayed at one of these positions, -1.0 is returned
for this position.
In order to retrieve this information, the parameter
'depth_persistence'"depth_persistence""depth_persistence""depth_persistence""depth_persistence" must have been set to 'true'"true""true""true""true"
with set_scene_3d_paramset_scene_3d_paramSetScene3dParamSetScene3dParamSetScene3dParam.
The window coordinates RowRowRowRowrow, ColumnColumnColumnColumncolumn must be provided with
respect to the current image part. As a consequence, these coordinates are
subpixel coordinates. Given the current image part (row1,column1,row2,
column2), the upper left corner corresponds to the coordinates
(row1 - 0.5, col1 - 0.5). Accordingly, the bottom right corner
corresponds to the coordinates (row2 - 0.5, col2 - 0.5). Use
get_mposition_sub_pixget_mposition_sub_pixGetMpositionSubPixGetMpositionSubPixGetMpositionSubPix or get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixGetMbuttonSubPix to obtain these
coordinates directly.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on internal data level.
