◆ BKE_tracking_reconstruction_check()

bool BKE_tracking_reconstruction_check ( struct MovieTracking * tracking,
struct MovieTrackingObject * tracking_object,
char * error_msg,
int error_size )

Perform early check on whether everything is fine to start reconstruction.

◆ BKE_tracking_reconstruction_context_free()

void BKE_tracking_reconstruction_context_free ( struct MovieReconstructContext * context)

Free memory used by a reconstruction process.

◆ BKE_tracking_reconstruction_context_new()

MovieReconstructContext * BKE_tracking_reconstruction_context_new ( struct MovieClip * clip,
struct MovieTrackingObject * tracking_object,
int keyframe1,
int keyframe2,
int width,
int height )

Create context for camera/object motion reconstruction. Copies all data needed for reconstruction from movie clip datablock, so editing this clip is safe during reconstruction job is in progress.

◆ BKE_tracking_reconstruction_finish()

bool BKE_tracking_reconstruction_finish ( struct MovieReconstructContext * context,
struct MovieTracking * tracking )

Finish reconstruction process by copying reconstructed data to an actual movie clip data-block.

◆ BKE_tracking_reconstruction_scale()

void BKE_tracking_reconstruction_scale ( struct MovieTracking * tracking,
float scale[3] )

Apply scale on all reconstructed cameras and bundles, used by camera scale apply operator.

◆ BKE_tracking_reconstruction_solve()

void BKE_tracking_reconstruction_solve ( struct MovieReconstructContext * context,
bool * stop,
bool * do_update,
float * progress,
char * stats_message,
int message_size )

Solve camera/object motion and reconstruct 3D markers position from a prepared reconstruction context.

stop is not actually used at this moment, so reconstruction job could not be stopped.

do_update, progress and stat_message are set by reconstruction callback in libmv side and passing to an interface.
