anvil-reduce

Volume-based mesh proxy generator: voxelize, marching cubes, smooth, remesh. Fast, watertight, hands-off. Native Rust core, Python bindings via PyO3.

Install

pip install anvil-reduce

Inside DCCs:

mayapy -m pip install anvil-reduce          # Maya
hython -m pip install anvil-reduce          # Houdini
# Blender: install into the addon's bundled Python or vendor the wheel

Quick start

One-shot file pipeline (the path most pipeline TDs want):

from anvil_reduce import proxy_from_path

result = proxy_from_path(
    "hero.obj",
    "hero_proxy.obj",
    quality="balanced",          # "fast" | "balanced" | "high"
    transfer_normals=True,
)
print(f"{result['input_faces']} -> {result['output_faces']} in "
      f"{result['wall_seconds']:.2f}s")

NumPy-driven workflow:

import numpy as np
from anvil_reduce import Mesh, generate_proxy

mesh = Mesh.from_numpy(positions, indices)   # (N,3) f64, (M,3) u32
proxy = generate_proxy(mesh, quality="balanced", target_faces=20_000)
positions, indices = proxy.positions(), proxy.indices()

Quality presets

Preset	voxel_res	smooth	remesh	sdf
fast	64	10	0	off
balanced	128	10	3	off
high	256	15	5	on

Override individual knobs by passing them explicitly. target_faces auto-picks voxel_res. dilation controls hull tightness (0 = tight, 1-3 = looser).
