XR & Digital Twins

Rapidly build richly detailed, physics-aware objects for AR/VR and operational twins.

VFX & Product Visualization

Shorten look-dev with accurate materials, sharp edges, and 6K textures that hold up to close-ups.

Research & Education

Provide a reliable path from 2D imagery to verifiable 3D for labs teaching simulation, graphics, and robotics.

How to Use Seed3D 1.0

01

Upload

Provide a single RGB image or a small image set. Seed3D 1.0 analyzes geometry, materials, and scale.

02

Generate

Start the job. The model constructs clean topology, bakes PBR textures up to 6K, and validates physics constraints.

03

Review

Inspect mesh density, UVs, and materials. Quick checks confirm watertightness and self-intersections.

04

Export

Choose USDZ, USD, FBX, or GLTF. Packages are ready for Omniverse, Unity, Unreal, or your robotics simulator.

Why Choose Seed3D 1.0 over Traditional Modeling

Speed with certainty

Seed3D 1.0 compresses days of manual work into a short, predictable pipeline that still respects physics.

Accuracy where it matters

It keeps edges crisp, thin fins stable, and chamfers true—details that define premium 3D.

Ready for engines

With USDZ, USD, FBX, and GLTF, Seed3D 1.0 meets studio and robotics standards out of the box.

Flexible editing

Assets import neatly into Blender, Maya, and Houdini for custom rigging, LODs, and simulation tags.
