(Near)¶
The clipping plane distance from the camera pose in viewing direction.
This parameter has different restrictions depending on whether the (Camera) parameter is set.
Telecentric Projection¶
If (Camera) is not set, a telecentric projection is used and the view pose is defined by (ViewPose). The Near parameter then specifies the minimum distance to the view pose below which surface elements are excluded from the depth map. This can be used to exclude the working plane from the depth view.
Perspective Projection¶
If (Camera) is set, the perspective projection and view pose of the specified camera will be used. The Near parameter then defines the near clipping plane of the perspective projection. Any surface closer to the camera will be discarded.
Note
The Near parameter must be positive if the perspective projection is used, otherwise a “ParametersInvalid” error will be thrown.
