Cara VR 2.1 Release notes

Global Warp Tracking for Cara VR 2.1

Global Warp tracking integration

This feature reduces the manual work necessary when using the C_GlobalWarp node on moving footage. Instead of manually animating the points defining a constraint, it’s now possible to track the constraint, using the same spherical tracking algorithms behind the C_Tracker. Two workflows have been introduced: the first allows you to track directly within Global Warp using a new panel with simplified tracking controls, making the process faster and easier. The second allows you to track with a C_Tracker: export a constraint as a set of points in a C_Tracker node, then, after having tracked, re-import them back in the C_GlobalWarp.

Vertical Aligner for Cara VR 2.1

Vertical Aligner

The Vertical Aligner tool has been ported from Ocula, with some modifications to make it better suited for Cara VR workflows. It allows users to achieve a good stereo panorama without having to perform lengthy corrections post C_Stitcher. Unlike the Ocula version, the Cara VR Vertical Aligner can be used as attached directly to a Camera Solver, or by itself. It also consumes and produces Cara VR metadata that can then be used by the Stitcher to improve results. And because the Cara version is aware of spherical space, it provides better results when used on fisheye lenses.

Camera Solver and Camera Ingest for Cara VR 2.1

Camera Solver and Camera Ingest

The Camera Solver now includes experimental solver layouts to handle more generic camera setups, including planar, linear, and free arrangements. The experimental layouts, along side the spherical and nodal arrangements, provide more options when solving custom rig layouts. The new Camera Ingest node allows users to import cameras from other packages so they can be used with Cara VR’s Camera Solver, allowing for a more user-friendly animation of the camera parameters.

Cara VR 2.0 Release notes

Global Warp in Cara VR 2.0

Updated stitching tools

The new GlobalWarp node speeds up delivery of stitches while producing a higher quality 360 stitch with minimal ghosting. GlobalWarp adds additional controls for lining up key features in overlapping areas and allows you to add constraints to reduce warping on known straight lines in the rectilinear input images, even for objects overlapping multiple camera views.

Tracker in Cara VR 2.0

360 match-move and stabilisation

Cara VR’s Tracker node has been redesigned to simplify and accelerate the process of stabilisation and match-moving for a more comfortable VR experience and easier alignment of 3D elements. The new Tracker adds automatic tracking and stabilization to your 360 stitch. You can then use the existing user track workflows to refine the track and lock stabilisation to particular regions.

Stereo Colour Matcher in Cara VR 2.0

Ocula tools for stereo corrections

Cara VR 2.0 includes a suite of tools adapted from the powerful Ocula toolset which take the headache out of stereo cleanup, especially in footage with color, focus and alignment inconsistencies between views. This release includes updated versions of the Disparity Generator node, which generates high quality disparity vectors for depth estimation, Disparity To Depth for calculating depth from the disparity vectors, a new Stereo Colour Matcher for unifying color between left and right views, and New View, allowing you to rebuild one view from another, all optimized for use with 360 footage.
