# Specularity

 Specularity[s]is a graphics directive which specifies that surfaces of 3D graphics objects which follow are to be taken to have specularity s. Specularityuses specular exponent n.
• Specularity is added to diffuse reflection and glow components to determine the final rendered color of a surface. »
• With specularity s, a surface is taken to specularly reflect a fraction s of light that falls on it from simulated light sources.
• The specular exponent n defines how sharply the intensity of reflected light falls off away from the mirror-reflection direction. »
• The default specular exponent is 1.5. Higher values lead to more sharply defined reflections, typical of shinier materials. Values above 10 produce definite "specular highlights".
• The intensity of simulated light at an angle from the mirror-reflection direction is taken to be . When , the intensity is zero.
• Specularity[s] takes the reflected light to have the same color as the incident light from light sources.
• Specularity[col] specifies that the RGB components of the incident light should be multiplied by the RGB components of col. »
