Compare N assets

Pro

Upload 2–8 GLBs. SpatialPack runs visual-diff for every pair, builds an N×N similarity matrix, and lets you click any cell to drill into the per-orbit detail. Built for batch QA, recipe-sweep analysis, and version-comparing assets across a release.

Pro tier

N-way batch compare is a Pro feature.

Upload 2–8 GLBs to build an N×N similarity matrix in one shot — perfect for QA-ing a recipe sweep, comparing every release of a single asset, or sanity-checking a batch of optimizer outputs. Try the 4-asset sample to see the matrix, or upgrade for upload access.

Pairs in parallelPro

Default 1 (memory-safe). Pro can run up to 4 pairs at once for ~4× speedup on large N×N batches. Each parallel pair launches its own headless Chromium, so raising this trades RAM for wall-clock time.

Batch QA

QA a sweep of optimizer presets in one shot. The matrix tells you at a glance which presets diverge from the baseline.

Version comparison

Compare every release of a single asset to spot drift over time. Diagonal = self (SSIM 1.0); off-diagonal cells show pairwise SSIM.

Click-to-drill

Any cell opens the per-orbit detail panel (8-camera SSIM + ΔE94 + side-by-side render) for that pair — the same view the single-pair Compare uses.
