# Truck Component Simulation Meshes and Synthetic LiDAR Measurements

This is the synthetic dataset from the paper 

Alignment of Highly Resolved Time-Dependent Experimental and Simulated Crash Test Data
Jochen Garcke, Sara Hahner, and Rodrigo Iza-Teran
Fraunhofer Center for Machine Learning and SCAI & Institut für Numerische Simulation, Universität Bonn

The data is described in section 5.3 of the paper.

The subdirectory "simulations" contains the simulation results for the analyzed component from 150 simulations. This includes:
- the simulation results for 100 simulations and every second timestep from 19 to 99
  - file: format: sim_xx_t_yy.dat (xx is the number of the simulations, yy the timestep)
  - every file contains the 1714 3D coordinates of the mesh's vertices
- the complete eigenbasis: 
  - file: evec_LaBel.dat
  - size: 1714 x 1714
  - the columns are the eigenvectors, ordered by highest to lowest value of the corresponding eigenvalues
- an example simulation mesh, which is constant over time: 
  - Wavefront OBJ file: sim_020_tt_019.obj
  - this file contains a list of vertex coordinates and a list of faces

The subdirectory "experiments" contains the synthetic LiDAR scans of 79 simulation results from every second timestep from 19 to 99
- file format: exp_xx_t_yy.dat (xx is the number of the simulations, yy the timestep)
- every file contains the scanned 3D coordinates by the LiDAR scanner
