Codrops 사례 연구
A window with depth.
섹션 · MIT
갤러리 안에서는 화면을 벗어나거나 움직임을 멈추면 예제도 닫힙니다. 다시 재생할 때는 처음부터 시작해요.
저장한 HTML에서는 갤러리의 재생 설정이 적용되지 않아요.

# A window with depth.
Independent article case study. Domain: website consumer / Design Engineering presentation.
One normalized pointer model drives bounded transforms for three independently illustrated DOM/SVG layers. Direct input and bound-model modes share the same render function, with reset and native coordinate controls. The setting is a botanical display, without game, staking, transaction or provider-runtime behavior.
## Attribution and evidence
Studied: [Integrating Rive into a React Project: Behind the Scenes of Valley Adventures](https://tympanus.net/codrops/2025/05/12/integrating-rive-into-a-react-project-behind-the-scenes-of-valley-adventures/), Zajno. Article SHA-256: 3e19adb5c6ce1a5b7573727907ae6166999e3976ab0a8be0e622bce7b4dce3ed. Analysis SHA-256: 47861a8e7d1f7dfdec3b2e0215d7af3a27e8a9bde2530fc767358cd4d740c498. Source revision: 42d6e9051858fd0ee94d7f0f54f51e16ec59ed2b1e2cbe7ef3ba5b7b51b78f93. The revision hashes the article/analysis hashes, the analyst principle and code-block evidence references; it identifies studied evidence, not a claim that the original demo executes.
Original acquisition: unresolved. Original license: unverified. originalSourceAcquired: false. Ten public React/Rive integration fragments and a sandbox reference are present, but the original hero .riv file, complete state-machine schema and artwork rights were not acquired.
No original article prose, code, artwork, source project or screenshot is distributed here. The authored-code MIT notice applies only to the independent implementation. The study is a botanical DOM/SVG parallax example, not a Rive file integration or game interface. No Chumbi artwork, NFT program, staking, transactions or rewards are included.
## Initial state and controls
Move a shared two-axis input across an original botanical window. Background, middle and foreground layers use different depths while the labels stay still.
The page starts stationary. Play motion, where present, advances this study’s presentation until paused; text, bounce, portrait, orbit, strand and mascot motion loops, while the event composer stops at its endpoint. Scroll studies advance through ordinary document scroll or their chapter buttons. Static view stops time-based motion; manual controls still inspect values. The three scroll studies instead show every chapter in ordinary reading flow. Pointer parallax centers its decorative layers.
Initial control values:
| Control key | Value |
| --- | --- |
| x | 20 |
| y | -15 |
| depth | 25 |
| mode | bound |
## Running and editing
Open index.html directly. It contains all runtime code and visuals and needs no package install, account, network, remote asset or browser-origin storage. Edit its inline style and script to change the downloaded page. styles.css and script.js are reference copies of the inline source; changing those copies alone does not change the running page. Repository regeneration overwrites index.html and all generated copies, including any manual edits. Keep a separate copy when editing a download. The repository authoring modules in vendor/codrops-article-studies/scenes-*.mjs and runtime.mjs regenerate these copies through node scripts/build-codrops-article-studies.mjs. Repository regeneration also needs the private source evidence; downloaded-page execution does not.
## Verification boundary
This generation passed the captured article/analysis hash checks, exact ID membership, local canonical Markdown anchor/hash checks, implementation-symbol checks, JavaScript parsing, semantic main/title counts, duplicate-ID checks and runtime URL/storage exclusion. The manifest codeFiles entries identify every emitted file by SHA-256. Each code symbol is a searchable named function, not a claimed executed call trace. Proposed checks are in KNOWLEDGE.json. runtime_verified: false. SG artifact capture proves only a recorded initial render; no interactive runtime, keyboard, accessibility, comfort or performance result is claimed.
Manual Chrome interaction is blocked by extension UI in this session. No alternate browser-control route was used. Preview sizing is native responsive width. Initial-render captures are tracked separately at site/artifacts/full-import/preview-posters/index.json and site/artifacts/full-import/preview-posters/visual-review.json in the repository. No capture receipt is bundled with this download. The bounded initial-render matrix requests all 21 studies at 320 pixels and three representative studies at 1280 pixels; the separate poster surface is 640 × 420. The authored CSS also adapts at 375 and 768 pixels, without claiming those widths were captured. A width request does not mean that capture exists or passed. Motion starts on explicit playback; system reduced motion and the Static view switch stop it.

Applied canonical sections and current-authoring hashes are recorded in KNOWLEDGE.json. No design-terminology records are relied on. External references within canonical guidance were not independently rechecked by this implementation lane; only the local sections and article capture identities were checked. Root Layout corpus, Game UI, provider integrations and publisher export claims were rejected as outside this lane.
