React Three Fiber 3D renderer for json-render. Use when working with @json-render/react-three-fiber, building 3D scenes from JSON specs, rendering meshes/lights/models/environments, or integrating Three.js with json-render catalogs.
React Three Fiber renderer for json-render. 19 built-in 3D components.
| Entry Point | Exports | Use For |
|---|---|---|
@json-render/react-three-fiber/catalog | threeComponentDefinitions | Catalog schemas (no R3F dependency, safe for server) |
@json-render/react-three-fiber | threeComponents, ThreeRenderer, ThreeCanvas, schemas | R3F implementations and renderer |
Pick the 3D components you need from the standard definitions:
Box -- width, height, depth, materialSphere -- radius, widthSegments, heightSegments, materialCylinder -- radiusTop, radiusBottom, height, materialCone -- radius, height, materialTorus -- radius, tube, materialPlane -- width, height, materialCapsule -- radius, length, materialAll primitives share: position, rotation, scale, castShadow, receiveShadow, material.
AmbientLight -- color, intensityDirectionalLight -- position, color, intensity, castShadowPointLight -- position, color, intensity, distance, decaySpotLight -- position, color, intensity, angle, penumbraGroup -- container with position/rotation/scale, supports childrenModel -- GLTF/GLB loader via url propEnvironment -- HDRI environment map (preset, background, blur, intensity)Fog -- linear fog (color, near, far)GridHelper -- reference grid (size, divisions, color)Text3D -- SDF text (text, fontSize, color, anchorX, anchorY)PerspectiveCamera -- camera (position, fov, near, far, makeDefault)OrbitControls -- orbit controls (enableDamping, enableZoom, autoRotate)Reusable Zod schemas for custom 3D catalog definitions:
3D specs use the standard json-render flat element format:
