## Install
|
||||
|
||||
<InstallCommand command="npx hyperframes add cosmic-orb" />
|
||||
|
||||
That writes one file: `compositions/cosmic-orb.html`.
|
||||
|
||||
## Add it to your video
|
||||
|
||||
It runs for 10 seconds at 1920×1080. Paste this into your composition:
|
||||
|
||||
```html index.html
|
||||
<div
|
||||
data-composition-id="cosmic-orb"
|
||||
data-composition-src="compositions/cosmic-orb.html"
|
||||
data-start="0"
|
||||
data-duration="10"
|
||||
data-track-index="1"
|
||||
data-width="1920"
|
||||
data-height="1080"
|
||||
></div>
|
||||
```
|
||||
|
||||
Move it in time with `data-start`. Put it on a different timeline row with
|
||||
`data-track-index`. See [data attributes](/concepts/data-attributes) for the rest.
|
||||
|
||||
## Change how it looks
|
||||
|
||||
Set these CSS variables on the block:
|
||||
|
||||
- `--hue` — Nebula hue. Defaults to `268`.
|
||||
- `--accent` — Accent hue. Defaults to `196`.
|
||||
- `--spin` — Spin rate (turns per second). Defaults to `0.035`.
|
||||
- `--stars` — Star density. Defaults to `1`.
|
||||
- `--glow` — Glow intensity. Defaults to `1`.
|
||||
- `--size` — Orb size (fraction of frame height). Defaults to `0.86`.
|
||||
- `--pulse` — Beat pulse (0-1, flat value when no envelope is set). Defaults to `0`.
|
||||
- `--pulseenvelope` — Beat pulse envelope: comma-separated 0-1 samples spread evenly across the clip. Defaults to ``.
|
||||
- `--backdrop` — Backdrop. Defaults to `#04040a`.
|
||||
|
||||
{/* hf:generated-footer */}
|
||||
|
||||
Tagged `webgl` `shader` `background` `showcase` `3d`.
