|
|
*
|
|
* When your Spline scene is ready, choose one of three methods:
|
|
*
|
|
* ── Method A (HTML — recommended) ────────────────────────────────────
|
|
* Open index.html → find #spline-layer → delete .spline-placeholder
|
|
* → paste in:
|
|
*
|
|
* <spline-viewer
|
|
* url="https://prod.spline.design/YOUR_SCENE_ID/scene.splinecode"
|
|
* events-target="global"
|
|
* ></spline-viewer>
|
|
*
|
|
* ── Method B (JavaScript runtime) ────────────────────────────────────
|
|
* Call from console or your code:
|
|
* window.Lumerel.loadSplineScene('https://prod.spline.design/…')
|
|
*
|
|
* ── Method C (Interactive scenes) ────────────────────────────────────
|
|
* After scene loads, enable pointer events:
|
|
* window.Lumerel.enableSpline()
|
|
*
|
|
* The <spline-viewer> web component is already loaded via CDN
|
|
* in the <head> of index.html — no extra imports needed.
