2005/10/03 Release 4.06
|
||||
Changed the core for distance computation.
|
||||
Current version uses the lib flexible search structures.
|
||||
Now the comparison can be done exploiting a static uniform grid,
|
||||
a hashed grid or a hierarchy of AA box.

|
||||
2005/04/04 Release 4.05
|

Added saving of Error Histogram
|

|
||||
2005/01/26 Release 4.04
|
||||
Gcc compiling issues
|
||||
Moved to the library core the code for computing min distance froma a point to a mesh using a uniform grid.
|
||||
Slightly faster.
|
||||
|
||||
2005/01/03 Release 4.03
|
||||
Better ply compatibility, and improved error reporting
|
||||
|
||||
2004/11/29 Release 4.02
|
||||
removed bug in printing Hausdorf distance,
|
||||
removed bug in command line parsing,
|
||||
upgraded import mesh library to support off format

A different scheme is used to sample vertices and edges: vertices are sampled in the straightforward manner,
|
||||
while edges are sampled by uniformly interleaving samples along each edge.
|
||||
|
||||
Three different Spatial indexing structures can be used to find the closest point to a sample, a Statically Allocated Uniform Grid, a Hashed Uniform Grid and a Hierarchy of axis aligned bounding boxes.

--- Basic usage ---

Metro is a command-line tool which allows the user to select among different sampling schemes.
