grazingOf

How edge-on the surface is to the viewer: 0 face-on, 1 grazing.

grazingOf(n: Expr, view: Expr): Expr

Import materials from shaders/std and use materials.grazingOf.

The input the fresnel words take when you have a view ray. Without one, use grazingFlat.

Parameters

`n`	`Expr`
`view`	`Expr`

const grazing = grazingOf(n, viewRay(params, field))
