Kartaverse kvrPlane Node

[Andrew Hazelden]

Hi. Today I added new DCTL fuse to Kartaverse that provides a "plane to sphere" style of conversion. The Kartaverse "kvrPlane" node allows you to place a flat image into a 180VR, or 360VR image projection. It supports monoscopic and stereo 3D output.

There is an example comp located at the PathMap location of:

Reactor:/Deploy/Comps/Kartaverse/KartaVP/kvrPlane/Demo kvrPlane v001.comp

The node based layout is typically:
Text+/Loader/MediaIn -> kvrPlane -> AutoDomain -> kvrViewer

There are onscreen control handles in the viewer window which make it quick to position content visually using a "Center" X/Y point control to apply yaw/pitch rotation to the imagery when it is projected into the spherical image projection.

If you are working with non 1:1 aspect ratio source imagery, the "Resolution Gate Fit" control allows you to fit the imagery using either a "Stretch", "Width", or "Height" option. This is great if you want to place a small logo or other custom graphic element and not have to worry about the source image's dimensions and aspect ratio.

Note: At the moment, the 180VR and 360VR options only work on macOS systems with a Metal based GPU. Support for CUDA and OpenCL GPUs on Windows and Linux is under development now.
