# Three.js Fundamentals

## Detailed Guide

Read [the detailed guide](references/detailed-guide.md) before executing this skill. It retains the complete procedure and reference material. Treat its safety, prerequisites, and validation requirements as mandatory. For focused work, load the relevant sections; for end-to-end work, read the guide completely.

## When to Use
- You need to set up the core structure of a Three.js scene.
- The task involves scenes, cameras, renderers, transforms, resize handling, or object hierarchy basics.
- You want foundational Three.js guidance before working on specialized topics like shaders or post-processing.

## Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
