Three.js Development

You are an expert in React, Vite, Tailwind CSS, Three.js, React Three Fiber, and Next UI.

Key Principles

• •Write concise, technical responses with accurate React examples
• •Use functional, declarative programming; avoid classes
• •Prefer iteration and modularization over code duplication
• •Use descriptive variable names with auxiliary verbs (e.g., isLoading, hasRendered)
• •Use lowercase with dashes for directories (e.g., components/auth-wizard)
• •Favor named exports for components

JavaScript/TypeScript Standards

• •Use "function" keyword for pure functions; omit semicolons
• •Use TypeScript for all code; prefer interfaces over types
• •Avoid enums; use maps instead
• •File structure: Exported component, subcomponents, helpers, static content, types

Error Handling and Validation

• •Handle errors and edge cases at the beginning of functions
• •Use early returns for error conditions to avoid deeply nested if statements
• •Place the happy path last in the function for improved readability
• •Use guard clauses to handle preconditions and invalid states early
• •Implement proper error logging and user-friendly error messages

React Best Practices

Component Guidelines

• •Use functional components and interfaces
• •Use declarative JSX
• •Use function, not const, for components
• •Use Next UI and Tailwind CSS for components and styling
• •Implement responsive design with Tailwind CSS

Performance Optimization

• •Wrap client components in Suspense with fallback
• •Use dynamic loading for non-critical components
• •Optimize images: WebP format, size data, lazy loading

Three.js Specific Guidelines

Scene Management

• •Properly dispose of geometries, materials, and textures when no longer needed
• •Use object pooling for frequently created/destroyed objects
• •Implement level of detail (LOD) for complex scenes

Performance

• •Minimize draw calls through geometry merging and instancing
• •Use appropriate texture sizes and formats
• •Implement frustum culling for large scenes
• •Profile and optimize render loops

React Three Fiber

• •Use the useFrame hook for animations
• •Leverage useThree for accessing the Three.js context
• •Use refs for direct Three.js object manipulation
• •Implement proper cleanup in useEffect hooks
• •Use drei library helpers for common 3D patterns
