fresnel.material¶

Overview

fresnel.material.Material

Define material properties.

Details

Materials describe the way light interacts with surfaces.

class fresnel.material.Material(solid=0, color=(0, 0, 0), primitive_color_mix=0, roughness=0.3, specular=0.5, spec_trans=0, metal=0)¶

Define material properties.

Materials control how light interacts with the geometry.

Parameters

solid (float) – Set to 1 to pass through a solid color, regardless of the light and view angle.
color (numpy.ndarray or array_like) – (3, float32) - Linear RGB color of the material.
primitive_color_mix (float) – Set to 1 to use the color provided in the Geometry, 0 to use the color specified in the material, or a value in the range [0,1] to mix the two colors.
roughness (float) – Roughness of the material. Nominally in the range [0.1,1].
specular (float) – Control the strength of the specular highlights. Nominally in the range [0,1].
spec_trans (float) – Control the amount of specular light transmission. In the range [0,1].
metal (float) – Set to 0 for dielectric material, or 1 for metal. Intermediate values interpolate between the two.
