quadric_lod
Generates LOD mesh based on quadric error metric with heuristics. See the report document for details.
Usage
python decimate.py [-h] [-a] [-b BOUNDARY] [-t THRESHOLD] [-o OUTPUT] [-p] [-s SCAN] input n
Positional arguments
input Path to input mesh file, the OBJ file should be trianglulated
and does not contain edges, normals, or texture coordinates
n Number of decimation iteration
Optional arguments:
-h, --help show help message and exit
-a, --area Turn off surface area heuristic
-b BOUNDARY, --boundary BOUNDARY
Boundary constraint factor, use 0 to turn off
-t THRESHOLD, --threshold THRESHOLD
Pair decimation threshold relative to mean extent of
the mesh
-o OUTPUT, --output OUTPUT
Path to output file
-p, --plot Plots loss history
-s SCAN, --scan SCAN Scan the entire loss curve, save model every [-s]
steps after [n] steps
Requirements
numpy (for linear algebra)
matplotlib (for plotting loss curve)
tqdm (for progress bar)
