Raw Normal View History

Camera tracking integration =========================== - ColaMD moved from OpenNL to extern/. It'll be needed for libmv. Also, it's a bit updated from year 1999 to 2007. Need to be tested for regressions. - Updated bundling script for libmv. Now it uses fuller subset of this library. - Bundled new libmv. - Request from Keir: add command line argument to toggle logging stuff on. Currently, if Blender is launched with -d argument libmv would start printing logging messages. There's no argument to increase verbosity, but there's API in libmv-capi, so it'll be easy to add. - Finally fixed crash when ibuf is acquiring with user=NULL. - Added ActiveClip property to the scene. This clip is used as default value for new match-moving constraints. - Added some flags to Display panel of View3D. Related on displaying match-moving stuff. - Internal change: bundles data moved inside to MovieTrackingTrack. - Initial implementation of 3d reconstruction. - Added constraint "Camera Solver". This constraint is supposed to be used to make camera follow the reconstructed camera path. - Added "reference" property to "Follow Track" constraint. Now object could be "parented" to 2D track position or to 3D bundle position. The very quick guide: To use reconstruction you should have footage with tracked markers, choose two keyframes in "Tracking settings" panel. There should be quite noticeable parallax effect between this two frames. This is used to initialize reconstruction stuff. Camera data (focal length and optical center) should be filled in "Camera Data" panel. Optical center is often the center of image, so it'll be filled in automatically. You should also set values for undistortion (K1, K2 and K3). Currently, there's no any visualization for this parameters and approach of "change value -> reconstruct -> see what've changed" is the only way for now. Libmv team is working on auto-calibration tool, so it should be easier to gather this coefficients in nearest (i hope) future. There's also no scene orientation stuff. Basic workflow: - Open footage. - Set markers and track them. - Fill in camera data and keyframes. - Hit "Solve Camera" button. - Add "Camera Solver" constraint to camera in scene. - Choose movieclip in that constraint. - To see bundles in 3D viewport active clip should be set in scene buttons.
