flareFrame
The shared frame of a camera lens flare, which every flare* part reads.
flareFrame(slots: {position: PropRef; intensity: ArgSpec; edgeFade: ArgSpec}): LightValue
Import light from shaders/std and use light.flareFrame.
position is the light's position prop. intensity scales the whole flare and edgeFade (0–1) dims it as the light nears the canvas edge. Bind it once with a name and hand the same value to each part, then close the stack with flareComposite.
Parameters
| Name | Type | Notes |

slots | {position: PropRef; intensity: ArgSpec; edgeFade: ArgSpec} |
Example
const flare = local(flareFrame({position: p('lightPosition'), intensity: p('intensity'), edgeFade: p('edgeFade')})(params), 'flare')
