`tridecimator fileIn fileOut face_num [opt]`
|

|

Tridecimator is a commandline mesh simplifier based on a variant of the quadric error edge collapse strategy.
|
||||
It supports `PLY, OFF, OBJ` format for input and output and require a target number of faces.
|
||||
The following options are supported:
|
||||
|
||||
-e# QuadricError threshold (range [0,inf) default inf)
|
||||
-b# Boundary Weight (default .5)
|
||||
-p# Quality quadric Weight (default .5)

-q# Quality threshold (range [0.0, 0.866], default .3 )
|
||||
-n# Normal threshold (degree range [0,180] default 90)
|
||||
-w# Quality weight factor (10)

-E# Minimal admitted quadric value (default 1e-15, must be >0)

-Q[y|n] Use or not Face Quality Threshold (default yes)
|

-H[y|n] Use or not HardQualityCheck (default no)
|

-N[y|n] Use or not Face Normal Threshold (default no)
|

-P[y|n] Add or not QualityQuadric (default no)

-A[y|n] Use or not Area Checking (default no)

-O[y|n] Use or not vertex optimal placement (default yes)

-B[y|n] Preserve or not mesh boundary (default no)
|

-T[y|n] Preserve or not Topology (default no)

-W[y|n] Use or not per vertex Quality to weight the quadric error (default no)

-C Before simplification, remove duplicate & unreferenced vertices

-- Some technical notes --

|

This simplification tool employ a quadric error based edge collapse iterative approach.
|
||||
Each possible collapse is scored taking into account
|
||||
- its quadric error
