FBX Viewer Download

Purpose & User Intent: This tool provides a downloadable FBX viewer and related metadata generation. It solves the need for asset preview workflows by delivering platform-specific viewer installers and integrity data without editing capabilities. Target users include 3D artists, game devs, asset managers, and pipeline engineers who must validate geometry, materials, animations, and scene scale offline before integration. It is used when a team approves an asset and requires a consistent, local preview while avoiding upload-to-cloud steps. Core Logic & Features: The tool maps inputs (OS, architecture, viewer version) to a download URL and release notes. Required features include platform validation, version parsing, and integrity checksum. Optional/advanced features add language packs, fallback mirrors, and preflight compatibility checks against FBX version compatibility. Outputs include download_url, file_size, checksum, and release_notes. The system avoids editing or rendering; it only supplies access to a viewer. Inputs & Outputs: Inputs: platform (string enum Windows/macOS/Linux), architecture (x86_64/arm64), version (string vMAJOR.MINOR.PATCH), language (optional). Outputs: download_url (string), file_size_mb (number), sha256_checksum (string), release_notes (string). Validation ensures platform supports the requested version; missing inputs trigger validation errors; outputs follow naming conventions and formatting: URL, MB integer or decimal, 64-hex digest. Algorithms & Calculations: Core algorithm selects a binary URL based on OS/arch/version, validates signature if available, and reports file_size based on release metadata. Checksums are computed by the release process; optional delta updates are omitted. Version comparison follows semantic versioning rules; fallback to latest if version unspecified. Error & Edge Cases: Unsupported platform/architecture returns a clear error and suggested alternatives. Missing version or download URL triggers validation errors. Network failures during URL retrieval map to retriable errors with cached metadata. Incomplete asset metadata results in conservative defaults and explicit notes. Industry/Region & Localization: Tools align with software distribution standards; units are MB for size; no regional licensing constraints are assumed beyond standard export controls. Localization support can include language packs but does not affect core download logic. Assumptions & Exclusions: Assumes internet access for URL retrieval at build time; excludes in-app editing, 3D rendering, or asset conversion features. No branding or marketing content is included.
