Interface: Mesh3dTraceLighting

Plotly's lighting model: coefficients of the ambient, diffuse and specular light. With scene.lighting, they scale the scene's lights.

Properties

Property	Type	Default value	Description
ambient?	number	0.8	Ambient light: the share of the color shown whatever the direction of the light. Range: 0 – 1
diffuse?	number	0.8	Diffuse light: the share of the color lit by the light (Lambert). Range: 0 – 1
facenormalsepsilon?	number	0.000001	Triangles whose normal is shorter than this get no normal in flat shading (degenerate triangles). Range: 0 – 1
fresnel?	number	0.2	Fresnel reflection: how much more light surfaces reflect at grazing angles. Range: 0 – 5
roughness?	number	0.5	Roughness of the surface: the spread of the specular highlights. Range: 0 – 1
specular?	number	0.05	Specular highlights: the light reflected toward the eye. Range: 0 – 2
vertexnormalsepsilon?	number	1e-12	Vertex normals ignore triangle normals shorter than this (tiny triangles do not skew smooth shading). Range: 0 – 1
