Nexus Architect Tool Module
|
|
|
|
This module provides autonomous 3D world generation capabilities for the Three.js Nexus.
|
|
It enables Timmy to design and build rooms, portals, lighting, and architectural features
|
|
through LLM-generated Three.js code that is validated for safety before execution.
|
|
|
|
Available tools:
|
|
- nexus_design_room: Design a new room with specified theme, dimensions, and features
|
|
- nexus_create_portal: Create portals connecting rooms with visual effects
|
|
- nexus_add_lighting: Add lighting systems (ambient, point, directional, spot)
|
|
- nexus_add_architecture: Add architectural elements (walls, floors, ceilings, decor)
|
|
- nexus_validate_scene: Validate and lint generated Three.js code
|
|
- nexus_export_scene: Export the current scene to JSON or JS format
|
|
|
|
Features:
|
|
- LLM-powered Three.js code generation with structured prompts
|
|
- Code safety validation (syntax check, sandboxing, dangerous API detection)
|
|
- Scene graph management and serialization
|
|
- Portal network management for room connectivity
|
|
- Lighting system design with energy/consistency checks
|
|
- Architecture component library integration
|
|
|
|
Usage:
|
|
from nexus_architect import nexus_design_room, nexus_validate_scene
|
|
|
|
# Design a meditation chamber
|
|
result = await nexus_design_room(
|
|
name="Zen Garden",
|
|
theme="meditation",
|
|
dimensions={"width": 20, "height": 10, "depth": 20},
|
|
features=["water_feature", "floating_lanterns", "bamboo_grove"]
|
|
)
|
|
|
|
# Validate the generated code
|
|
validation = await nexus_validate_scene(generated_code)

1. STRUCTURE:
|
|
- Create a complete, self-contained function called `createRoom()`
|
|
- Return a THREE.Group containing all room elements
|
|
- Include proper disposal methods for memory management
|
|
|
|
2. GEOMETRY:
|
|
- Use appropriate geometries for the theme (BoxGeometry for walls, PlaneGeometry for floors, etc.)
|
|
- Optimize by reusing geometries where possible
|
|
- Keep polygon count reasonable (< 10,000 triangles per room)
|
|
|
|
3. MATERIALS:
|
|
- Use MeshStandardMaterial for PBR lighting
|
|
- Set appropriate roughness/metalness values
|
|
- Include emissive materials for glowing elements
|
|
|
|
4. LIGHTING:
|
|
- Include ambient light (0.3 intensity base)
|
|
- Add theme-appropriate accent lights
|
|
- Use shadows sparingly for performance
|
|
|
|
5. SAFETY:
|
|
- Only use allowed Three.js APIs
|
|
- No eval, Function, or dynamic code execution
|
|
- No network requests or external dependencies
