I accidentally swapped vertical and horizontal directions. Actually take a round horizontally is the working one ('A' and 'S' moves camera horizontally) and vertically is the one which should be fixed (need keys to move camera up and down). See attachments which shows the path of the camera moving around the model. There were more limitations solved by the new libgltf-0.0.1 release: - Camera can't be moved upward/downward directly (now use "E" and "Q" for that) - Vertical rotation had a limitation from +90 to -90 degree (relative to the initial orientation - Third one is hard to describe, but here is a model to reproduce it: https://wiki.documentfoundation.org/File:Packman_maze.odp The problem is that when the camera is moved inside the maze and trying to turn right/left at a corner during walk in the maze, then the camera not looks right/left as expected but behave strange. So just try to walk through the maze and will see the problem. Summary all of these problems is solved now: http://cgit.freedesktop.org/libreoffice/core/commit/?id=a60cc580212e2770c3aef7decfa09b64d4a3e52f For 4.3 it's waiting for review: https://gerrit.libreoffice.org/#/c/11194/ |
