Virtual Camera Workflows in R21.1
In the latest update, R21.1, we have introduced new virtual camera workflows that are specifically designed for extended reality (XR) applications. These workflows enable users to Create more interesting camera looks in setups like LED cubes, where a single camera setup may not be enough. With virtual cameras, it is now possible to create multiple camera setups and change the perspective of both the pixels on the LED and the captured frame from the real camera.
Creating Virtual Cameras
To create a virtual camera, simply use the camera widget and treat it like a normal camera. The virtual camera will appear at the world center of the stage and can be placed anywhere. It is linked to a real camera in the stage, allowing for easy manipulation and setup. This means You can have a static shot or a dynamic shot using animation, giving you more control over your camera moves.
Adjusting Perspective and Pixels
The main AdVantage of virtual cameras is the ability to change the perspective of the scene. By placing the virtual camera in a different location, you can create a wide shot of the scene, even if your physical Studio has limited space. This is achieved by using set extension logic, where the alpha is filled with a 3D scene. The result is a live scene with a wide view from the virtual camera, seamlessly integrated with the live feed from the real camera.
Using Set Extension Logic
With set extension logic, you can create a camera move that suits your needs, whether it's a static shot or a dynamic one. By manipulating the pixels on the LED and adjusting the captured frame from the real camera, you can make it appear as if there is a camera in the right place. This is especially useful for scenes that require a pullback, where you want the virtual camera to provide a wider shot of the scene.
Adjusting Lens Intrinsics
Virtual cameras also allow you to adjust the lens intrinsics of the camera itself. You can choose to inherit the lens intrinsics or set specific local intrinsics. This is particularly useful when matching up multiple stages or when shooting pickup shots with the same lens behavior. You can easily set different field of views for different virtual cameras, enhancing the realism of your scenes.
Animating Virtual Cameras
Virtual cameras can be animated using the animate objects workflows available. By choosing the animate camera control option, you can set individual numeric values for the virtual camera. This allows you to create dynamic shots, such as pullback shots or dolly zoom effects. By keyframing the distance from pivot or the camera pivot point, you can achieve smooth camera movements within your XR setup.
Global vs Relative Coordinates
Virtual cameras can have global or relative coordinates, depending on your preference. Global coordinates allow you to precisely position the virtual camera in the 3D scene. On the other HAND, relative coordinates make the virtual camera move with the parent camera. This can be useful when you want to dynamically adjust the placement of the virtual camera Based on the parent camera's movement.
Integrating with Direction Controllers
Virtual cameras seamlessly integrate with the in-direction controllers inside the MR set. By cutting between real and virtual cameras, you can easily switch perspectives and create multi-camera shows with a single camera. This opens up possibilities for more creative and immersive XR experiences. You can even link the camera control to expressions or OSC to automate camera movements, making your virtual camera workflows even more versatile.
Conclusion
The introduction of virtual camera workflows in R21.1 brings added flexibility and creativity to XR applications. By creating virtual cameras, adjusting perspectives and pixels, animating camera movements, and using various camera controls, users can now achieve more dynamic and immersive visuals. Whether you are working with an LED cube setup or other XR scenarios, virtual cameras offer endless possibilities for capturing the perfect shot.
