Contrast3D & NainDev

Deterministic product conformance, interactive 3D inspection, and enterprise systems

Our technology portfolio is built as decoupled, single-responsibility systems with zero runtime coupling:

High-performance, embeddable 3D web component (<contrast-vehicle-viewer>) built with Three.js and strict TypeScript.

• In-browser validation: Verifies asset integrity using canonical SHA-256 seals emitted by DSE.
• Industrial visual fidelity: Physically based rendering, custom camera framing, exploded views, and hotspot annotations.
• Framework agnostic: Standards-compliant Custom Element with native DOM event dispatching.

Deterministic conformance chassis designed to measure facts, verify mathematical invariants, and issue auditable verdicts with zero subjective heuristics.

• 3D Conformance (rt-01 profile): Geometry validation, texel density distribution, manifold integrity, UV layout optimization, and material parameters.
• Dual Contract: Strict separation between reproducible mathematical facts (DeterministicResult) and non-deterministic environment metadata (AuditEnvelope).
• Interfaces: High-throughput HTTP API and Model Context Protocol (MCP) server for autonomous agents.

Collaborative commercial CRM engineered for client operations, deliverables, quotes, and workflow tracking.

• Backend: FastAPI with PostgreSQL and transactional audit trails.
• Frontend: Vue 3 SPA with strict typing.
• Integrations: Native consumer of DSE verification services and ContrastViewer components.

• Deterministic Verification: Every conformance check relies on strict quantization and published mathematical tolerances. No arbitrary heuristics.
• Decoupled Contracts: Products integrate exclusively through versioned APIs, schemas, and cryptographic checksums.
• Self-Hosted Infrastructure: Production workloads operate on dedicated hardware nodes with automated CI/CD gating and zero cloud runtime lock-in.
