Using the VRayCamera

---

Using the VRayCamera is the most direct way to utilize camera functionality in V-Ray for Nuke. These options include: tools that control the camera like a real camera with settings such as F-stop, shutter speed, and ISO film speed, turning the camera into a dome camera, and setting up a stereoscopic camera for rendering left/right pairs of images. The benefits of using the VRayPhysicalCamera include easier matching to a back plate and better simulation of real-life camera settings. It also gives full control over depth of field and motion blur effects.

For details on these options, see Physically Accurate Camera | VRayCamera.

 

Creating Camera Overrides in the VRayRenderer Node

---

Parameters can set scene-wide overrides to the VRayCameras, to primarily define the type of camera with which to render the scene, such as a standard pinhole camera or a panoramic VR camera.

Many parameters can be overridden including camera types and settings for Field of View (FOV), Depth of Field (DoF), and Motion Blur functions for the scene.

For details on these options, see Render Settings | VRayRenderer.

 

Using the Spherical type VRayCamera

---

The VRayPhysicalCamera Spherical type can capture a full 360-degree view of the scene. This can be especially useful for capturing a spherical panorama to be viewed in virtual reality applications (VR), or to project a spherical panoramic image onto geometry.

 

Using the Cube 6x1 type VRayCamera

---

The VRayCamera Cube6x1 type captures stereo cubemaps that can be viewed in VR headsets. The Cube6x1 type is a variant of the Box camera type that does not produce any empty space in the output image. To ensure a good resolution on VR devices, an 8k image for both the left and right eye images needs to be rendered. To reach a total 8k output for the VR device, the image resolution needs to be 12 x 1 in total. Each side of the cube needs to be 1,536 pixels, so the final resolution needs to be 18432 x 1536. This gives 28 megapixels or the equivalent of an 8k image which is 16 times that of HD resolution images.

 

Using the Fish eye type VRayCamera

---

The VRayPhysicalCamera Fish eye type is a special type of camera that captures the scene as if it is normal pinhole camera pointed at an absolutely reflective sphere which reflects the scene into the camera's shutter. Use the distance and FOV settings to control what part of the sphere will be captured by the camera. Note that the sphere always has a radius of 1.0.

 

Using the Cylindrical type VRayCamera

---

The VRayPhysicalCamera Cylindrical type is a special type of camera that captures the scene as if all the camera rays are cast from the center of the cylinder. In the vertical direction the camera acts as a pinhole camera, while in the horizontal direction it acts as a spherical camera.
