edgeGlowCompose

The final color from the folded state, over a transparent background.

edgeGlowCompose(
  st: { rgb: v3f; w: number; ba: number; ac: v3f; aa: number; },
  bloom: number,
): v4f

Import effects from shaders/std and use effects.edgeGlow.edgeGlowCompose.

bloom (0 to 1) sets how additively overlapping lights pile up; high values overdrive to white. Returns straight alpha, ready to return from the surface function.

Parameters

Example

return call(edgeGlowCompose, 'edgeGlowCompose', [state, uniforms.bloom])
