# React Three Fiber architecture
## When to activate
Use on tasks involving **Canvas mount, component lifecycle, useFrame**. For unrelated backend tasks do not load this skill.
## Implementation sequence
1. Choose perspective or orthographic camera, scene graph, model coordinate scale and render target.
2. Allocate geometry and materials outside render loop; use indexed/instanced buffers when repeated objects.
3. Constrain frame rendering to actual need, remove handlers and dispose GPU resources.
4. Integrate screen-space text as DOM accessible overlay and provide WebGL failure fallback.
5. Verify 320/375/768/1440, low end DPR=1 and interaction at 30/60FPS.
## Task-specific requirements
- Scope: **Canvas mount, component lifecycle, useFrame**. Design the full execution path, not a screenshot placeholder.
- Identify dependency version and actual supported API signature; avoid inventing APIs.
- Use original code, or install licensed upstream through its maintained tool if the user wants upstream code.
- Choose measurable states, error handling, accessibility and performance budgets.
## Implementation starter
**Implementation notes:** Model Canvas mount, component lifecycle, useFrame as explicit states, define input/output props and independent cleanup. Read master reference(s) below before writing code.
## Evidence / acceptance
- Renderer disposes; fallback provides content; no runaway GPU usage; no clipped subject at narrow widths.
- Test common, edge, interrupted, accessibility and responsive states; provide concrete artifacts/evidence.
