Rendering Using RayRender

CaraVR adds to a Camera tab to reconstruct stereographic VR sequences using slit scan techniques to the vanilla Nuke RayRender node. Ray rendering is a 3D to 2D process, so there's some setup involved before you can use RayRender.

When connected to a Scene node, the RayRender node renders all the objects and lights connected to that scene from the perspective of the Camera connected to the cam input (or a default camera if no cam input exists). The rendered 2D image is then passed along to the next node in the compositing tree, and you can use the result as an input to other nodes in the script.

RayRender is included as an alternative to Nuke's ScanlineRender because it is particularly suited to working with latlong material. RayRender can processes full 360 renders relatively quickly, and it includes a number of controls to improve the quality of stereo views towards the poles, when you look up or down wearing a headset.
