What it does

Includes 15+ built-in Three.js geometries (box, sphere, cylinder, torus, polyhedrons) plus path-based shapes (lathe, tube, extrude) with configurable segments and parameters
Create custom BufferGeometry with vertices, normals, UVs, and indices; supports dynamic updates via needsUpdate flag for animated deformations
Drei helpers provide convenient shape components (Box, Sphere, RoundedBox)

How to use r3f-geometry on Cursor

AI-first code editor with Composer

Prerequisites

Before installing skills in Cursor, ensure your development environment meets these requirements:

›Cursor installed and configured on your machine
›Node.js 16+ with npm — verify with node --version
›Active project directory where you want to add r3f-geometry

Run the install command

Execute the skills CLI command in your project's root directory to begin installation:

$npx skills add https://github.com/enzed/r3f-skills --skill r3f-geometry

Fetches r3f-geometry from enzed/r3f-skills and configures it for Cursor.

Select Cursor when prompted

The CLI shows a list of agents. Use arrow keys and space to select Cursor:

◆ Which agents do you want to install to?

│

│ ── Universal (.agents/skills) ────────────────

│ · Cline · Codex · Goose · Windsurf

│ ●Cursor(selected)

│ · Cursor · Aider · Continue

Verify installation

Confirm successful installation by checking the skill directory location:

.cursor/skills/r3f-geometry

Restart Cursor to activate r3f-geometry. Access via /r3f-geometry in your agent's command palette.

Security Notice

We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.

Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Use Cases

User Story & Requirements Generation

Create detailed user stories, acceptance criteria, and feature specs

Example

Generate user stories for 'password reset feature' with acceptance criteria, edge cases, and test scenarios

✓

Reduce spec writing time by 50%, ensure comprehensive coverage

Competitive Analysis

Research competitors, compare features, identify gaps

Example

Analyze 5 competitor products, create feature comparison matrix, suggest differentiation opportunities

✓

Complete competitive research in 2 hours instead of 2 days

Roadmap Prioritization

Evaluate features using frameworks (RICE, ICE, Kano) and create prioritized backlogs

Example

Score 20 feature ideas using RICE framework, generate prioritized roadmap with rationale

import { Canvas } from '@react-three/fiber' function Scene() { return ( <Canvas> <ambientLight /> <mesh position={[0, 0, 0]}> <boxGeometry args={[1, 1, 1]} /> <meshStandardMaterial color="hotpink" /> </mesh> </Canvas> ) }

Built-in Geometries

All Three.js geometries are available as JSX elements. The args prop passes constructor arguments.

Basic Shapes

// BoxGeometry(width, height, depth, widthSegments, heightSegments, depthSegments) <boxGeometry args={[1, 1, 1]} /> <boxGeometry args={[2, 1, 0.5, 2, 2, 2]} /> // SphereGeometry(radius, widthSegments, heightSegments, phiStart, phiLength, thetaStart, thetaLength) <sphereGeometry args={[1, 32, 32]} /> <sphereGeometry args={[1, 64, 64]} /> // High quality <sphereGeometry args={[1, 32, 32, 0, Math.PI]} /> // Hemisphere // PlaneGeometry(width, height, widthSegments, heightSegments) <planeGeometry args={[10, 10]} /> <planeGeometry args={[10, 10, 32, 32]} /> // Subdivided for displacement // CircleGeometry(radius, segments, thetaStart, thetaLength) <circleGeometry args={[1, 32]} /> <circleGeometry args={[1, 32, 0, Math.PI]} /> // Semicircle // CylinderGeometry(radiusTop, radiusBottom, height, radialSegments, heightSegments, openEnded) <cylinderGeometry args={[1, 1, 2, 32]} /> <cylinderGeometry args={[0, 1, 2, 32]} /> // Cone <cylinderGeometry args={[1, 1, 2, 6]} /> // Hexagonal prism // ConeGeometry(radius, height, radialSegments, heightSegments, openEnded) <coneGeometry args={[1, 2, 32]} /> // TorusGeometry(radius, tube, radialSegments, tubularSegments, arc) <torusGeometry args={[1, 0.4, 16, 100]} /> // TorusKnotGeometry(radius, tube, tubularSegments, radialSegments, p, q) <torusKnotGeometry args={[1, 0.4, 100, 16, 2, 3]} /> // RingGeometry(innerRadius, outerRadius, thetaSegments, phiSegments) <ringGeometry args={[0.5, 1, 32]} />

Advanced Shapes

// CapsuleGeometry(radius, length, capSegments, radialSegments) <capsuleGeometry args={[0.5, 1, 4, 16]} /> // Polyhedrons <dodecahedronGeometry args={[1, 0]} /> // radius, detail <icosahedronGeometry args={[1, 0]} /> <octahedronGeometry args={[1, 0]} /> <tetrahedronGeometry args={[1, 0]} /> // Higher detail = more subdivisions <icosahedronGeometry args={[1, 4]} /> // Approximates sphere

Path-Based Shapes

import * as THREE from 'three' // LatheGeometry - revolve points around Y axis function LatheShape() { const points = [
