Description
get_display_scene_3d_infoget_display_scene_3d_infoGetDisplayScene3dInfoGetDisplayScene3dInfoget_display_scene_3d_info returns information on the
3D object models in the 3D scene Scene3DScene3DScene3Dscene3Dscene_3d that have been displayed
with display_scene_3ddisplay_scene_3dDisplayScene3dDisplayScene3ddisplay_scene_3d in the window WindowHandleWindowHandleWindowHandlewindowHandlewindow_handle.
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_paramSetScene3dParamSetScene3dParamset_scene_3d_param.
- '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_paramSetScene3dParamSetScene3dParamset_scene_3d_param.
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_pixGetMpositionSubPixGetMpositionSubPixget_mposition_sub_pix or get_mbutton_sub_pixget_mbutton_sub_pixGetMbuttonSubPixGetMbuttonSubPixget_mbutton_sub_pix 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.
