3D & Spatial Design Tools
Designer-friendly 3D apps for hero scenes, product viz, and motion graphics.
The designer-facing 3D pipeline that ends up in 3D / WebGL (Three.js, R3F) or as rendered video / image. For traditional CAD see Mechanical CAD.
Browser-based / designer-friendly 3D
- ★ Spline — closed source, generous free tier (3 files, public). The default for "marketing-site hero scene" in 2026 — visual 3D editor with code export, React component export, and built-in interactions. Closed source but the tool that made web 3D approachable.
- ★ Womp — closed source, freemium; clay-modeling-style 3D in the browser; great for soft, illustrative 3D objects.
- Vectary — closed source, freemium; web-based 3D editor with AR export.
- Polycam — closed source, freemium; phone-based photogrammetry / Gaussian splatting.
Pro-grade OSS
- ★ Blender — free OSS (GPL); the most powerful free 3D tool ever made. Modeling, sculpting, rigging, animation, simulation, rendering (Cycles + Eevee), compositing, video editing. The pro pick for anyone who'll invest the learning time.
- glTF / USD — open formats; Blender exports both. glTF is the web-friendly answer; USD is the studio-pipeline answer.
Sculpting / texturing OSS
- ★ Blender (sculpt mode) — free; competitive with ZBrush for many use cases.
- Quixel Mixer — closed source, free (Epic-owned); texture-painting on meshes. Phasing in favor of Adobe Substance ecosystem but still usable.
- Material Maker — free OSS Substance Designer alternative.
- Armor Paint — paid OSS (you pay for binary, source is free); 3D paint app.
Real-time / rendering OSS
- Blender Eevee Next — real-time PBR renderer inside Blender.
- ★ Three.js + React Three Fiber — see 3D / WebGL; the runtime side.
- Godot — see Game Dev; also a 3D editor.
- Unreal Engine — closed source, free (royalty after threshold); overkill for most design work.
Web export pipelines
- ★ glTF via Blender → R3F /
@react-three/drei— see 3D / WebGL. - Spline → React component export — direct.
gltf-pipeline+@gltf-transform/cli— optimize / compress glTF for the web.- Draco / Meshopt — geometry compression; cuts file size 5–10x.
Photogrammetry / scanning (free / freemium)
- Polycam — see above.
- Luma AI — closed source, freemium; phone-based capture + Gaussian splatting.
- RealityCapture (free for hobbyists) — closed source; Epic-owned; pro photogrammetry.
- Meshroom — free OSS photogrammetry pipeline.
Pick this if…
- Marketing site hero scene fast: Spline.
- Soft, illustrative 3D blobs / icons: Womp.
- Pro 3D, willing to learn: Blender.
- Phone-scanned 3D capture: Polycam or Luma AI.
- Optimize a glTF for web:
@gltf-transform/cli+ Draco. - Need it on the web at runtime: export glTF → React Three Fiber.
