VR-Szeneninspektion

Das VR Szeneninspektions-Add-on erweitert die nativen Virtual-Reality-Funktionen von Blender und stellt sie in der Benutzeroberfläche bereit. Der Funktionsumfang ist auf Anwendungsfälle zur Szeneninspektion beschränkt. Fortgeschrittenere Anwendungsfälle können durch weitere Entwicklung innerhalb von Blender ermöglicht werden.

Die VR- Unterstützung in Blender basiert auf der OpenXR- Spezifikation und erfordert einige Einrichtungsschritte. Diese werden im Abschnitt Head-Mounted Displays (HMD) erklärt.

Add-on aktivieren

1. Öffnen Sie Blender und gehen Sie zum Abschnitt Add-ons der Benutzereinstellungen Preferences (Einstellungen).

2. Suchen Sie nach „VR Scene Inspection“ und aktivieren Sie das Add-on aktivieren-Auswahl-Kästchen.

The VR Scene Inspection add-on interface is located in 3D Viewport ‣ Sidebar ‣ VR tab. Its different panels and features are described in the following sections.

VR Sitzung

VR-Sitzung starten

Versuchen Sie, eine Verbindung zur OpenXR-Plattform herzustellen, um das Ansichtsfenster mit einem HMD zu teilen.

Verfolgen

Positionsbezogen

Nur die Drehungen des Kopfes verfolgen und nicht zulassen, dass das HMD die Position des Betrachters im virtuellen Raum beeinflusst.

Absolut

Überspringen Sie die Augen-Offsets, die normalerweise hinzugefügt werden, um den Betrachter exakt an Landmarken zu platzieren. Dadurch kann der Tracking-Drehpunkt unabhängig von der HMD-Position definiert werden.

Bedienaktionen verwenden

Aktivieren Sie Standard-Controller-Aktionen für Viewport-Navigation, Controller-Tracking und Haptik.

View Settings

Zeigen

Boden

Legen Sie die Sichtbarkeit der Grundebene in der VR-Ansicht fest.

Anmerkungen

Legen Sie die Sichtbarkeit der Anmerkungsstriche in der VR-Ansicht fest.

Auswahl

Legen Sie die Sichtbarkeit von Auswahlkonturen in der VR-Ansicht fest.

Controllers

Set visibility of VR motion controllers. Requires enabling the Use Controller Actions option.

Custom Overlays

Set visibility of custom operator drawing (e.g. default teleport beam).

Object Extras

Set visibility of object extras, including empties, lights, and cameras.

Object Type Visibility

Set visibility of objects by type.

Controller Style

Bevorzugte Visualisierung von VR-Bewegungssteuerungen.

Clip Start/End

Clipping values of the VR view, as in the 3D Viewport.

View Scale

Scaling factor applied to the VR view for fine adjustments.

Fly Speed

Movement speed of the VR view when flying around the scene.

Location Scouting

Location Scouting allows the user to capture camera vantage points and assess the camera lens, focus, and aperture settings while being immersed within the 3D environment.

Capturing Shots

Capturing is done inside the VR session using a virtual director’s viewfinder, enabled in Location Scouting ‣ Viewfinder.

Using the Viewfinder, the user can control the camera settings, capture shots, and play back shots, while staying immersed in the VR environment. Once captured, shots can later be converted into scene cameras or markers during review.

VR Location Scouting Viewfinder Controls Diagram

Live Mode Actions

Focal Length Control

Increase / decrease the focal length (zoom) by pre-defined increments.

Toggle Depth of Field

Enable / disable Depth of Field, displayed visually within the Viewfinder and stored in the captured shot.

Set Focus Point

Set the Viewfinder focus point by aiming at the target. The Viewfinder crosshair will flash blue on successful focus, and red on failure.

Aperture Control

Increase / decrease the F-Stop ratio (which defines the amount of blurring) by pre-defined increments.

Playback Mode Actions

Browse Captured Shots

Browse captured shots, switching to next / previous capture.

Preview Active Shot in Space

Enable / disable display of the active capture in VR space as a camera overlay.

Delete Active shot

Delete the active shot. User confirmation is requested before deletion.

Reviewing Shots

Reviewing is done from the VR Location Scouting sidebar in the desktop 3D Viewport. From this panel, users can review shots, create cameras and markers from captured shots, and modify the VR Viewfinder settings.

Captured Shots List

A list view.

Remove Capture

Remove the selected capture.

Add Camera from Capture

Create a new camera object from the selected capture.

Add Marker from Capture

Create a new marker from the selected capture.

Browse Captures

Browse up/down the captured shots list.

Review VR Captures operator

This modal operator allows users to interactively review captures from the desktop 3D Viewport.

Once enabled, the 3D Viewport will be set to the active capture. The user may then browse and convert captures by either using the Captured Shots List, or the following keyboard controls:

Up	Previous Capture
Down	Next Capture
C	Add Camera from Capture
M	Add Marker from Capture
ESC/RMB	Exit Review

This operator is non-blocking. Clicking the Exit Review button or leaving the active 3D Viewport area will cause it to exit.

VR Viewfinder Settings

Hand

The hand on which the Viewfinder is displayed. This setting can also be changed directly from within the VR Session via controller Thumbstick Click.

Overscan

Border size of the darkened passepartout overlay.

Opacity

Opacity of the darkened passepartout overlay.

Landmarks

Landmarks are used to store reusable base poses (position and rotation) for the viewer in the virtual space. In addition, a base viewer reference scale can be set for landmarks of types Custom Object and Custom Pose.
