intensity Readonly

intensity: number

The strength of the effect in terms of how much brighter the surface becomes. The intensity at a given point on the surface is determined by the angle between the viewer's line of sight and the vector from the viewer to that point. Maximum intensity is produced when those vectors are perpendicular, and zero intensity is produced when those vectors are parallel (unless FresnelSettings.invert is true).

A value of zero turns off the effect. Values less than zero are clamped to zero. Typical values range between 0 and 1.
