Shape2Pose

Input Data

0_body directory contains information about human body structure, 1_input/off directory contains meshes, and 1_input/gt directory contains ground truth poses. Note: off meshes are not in meters, they should be scaled by 0.6.

File format a *.gt file (same format is used for *.pose.txt predicted poses):
     NPoses N - number of ground truth poses poses
     Pose X Regions R - for each pose X=0, .., N-1, R=number of prescribed points for pose X
     Region r name pnts 1 - lists assigned contact points for the pose, name is body part name
                                          NOTE: r maps to a line in 0_body/regions.txt file
     fid b1 b2 b3 x y z - contact point on the surface, fid is face id, b1-b3 barycentric coords, xyz - position
     ... list of all regions (repeated R times)...
     NSkeleton: P - indicates that next P values are skeleton parameters
     x y z alpha_up theta_1 ... theta_{P-4} - translation and rotation (around up) for a root, followed by P-4 joint angles                                           NOTE: see 0_body/regions_skeleton.txt file format description below
     ... list of all poses (usually there is only one ground truth pose)...

File format a 0_body/regions_skeleton.txt file (best understood from IKSolver.cpp code):
     scale 2.5 - constant scale applied to all distances below.
     joint1 joint2 axis length type [link_params] - describes a link between joint1 and joint2, other parameters:
                                          axis - pick a link direction (along X, Y, or Z coordinate),
                                          length - length of the link,
                                          type=[ball_socket, hinge, fixed] - type of the joint1, parameters depend on link type
                                          ball_socket - 3 euler angles (link_params = min/max values on each angle, multiply by π)                                           hinge - 1 angle w.r.t. a pivot (link_params = pivot_axis min/max angle, multiply by π)                                           fixed - no parameters, just a connection.
     ... list of links (first node is the root) ...

File format a 0_body/regions_symmetry.txt file:
     ... symmetric body parts appear on the same line ...
