Proof

What it does

Validate a glTF asset before it ships

Run official glTF conformance checks and measure geometry, textures, materials, animations, extensions, transfer weight, and likely runtime pressure from a public asset URL.

Tools in this app

01

Asset Check

asset_check

Fetches one direct public .gltf or .glb URL with its same-origin resources, runs the official Khronos glTF 2.0 validator, and profiles geometry, draw-call drivers, textures, materials, animations, extensions, and transfer weight. Returns validator issue counts and top coded issues, full asset statistics, per-resource status, disclosed pressure heuristics, an evidence-based grade, and prioritized fixes: use it whenever someone wants a 3D asset validated, profiled, or debugged before shipping. Small assets finish in a few seconds; large asset graphs can take up to 100 seconds.

02

Asset Compare

asset_compare

Runs the same official Khronos validation and delivery profile on two to four direct public .gltf or .glb URLs and ranks them: fewest validator errors first, then warnings, then the disclosed pressure composite. Returns per-asset grades, hashes, transfer and geometry/texture statistics, a best-first ranking with the winner, and tradeoffs that preserve visual-quality uncertainty: use it to pick between candidate exports or revisions of a 3D asset. Takes up to 110 seconds.

3D Asset Check questions

Scope and boundaries for 3D Asset Check.

01What can I check with 3D Asset Check?

Check the Khronos Duck GLB at its direct jsDelivr URL, or compare the binary and embedded glTF exports of that model to evaluate conformance, transfer weight, geometry, textures, materials, and animations.

02How should I read the result?

Read the official validator error count and first coded issue before the grade: any validator error is a conformance failure and should be fixed before performance work. Then use the grade, pressure evidence, and prioritized fixes for measured delivery, geometry, and texture pressure; those values are heuristics, not FPS or memory measurements. Reduced confidence, unmeasured resources, or truncation makes the profile incomplete, and complete ties provide no evidenced winner.

03What are its limits?

Inputs must be direct public .gltf or .glb URLs, and external resources are measured only where the fetch rules permit them; cross-origin or truncated resources remain disclosed as unmeasured. Structural validity and pressure estimates do not guarantee identical rendering, visual quality, or runtime behavior in every engine.
