nested const DefaultAmbientColor: TVector3 = (X: 0.2; Y: 0.2; Z: 0.2); |

Default material parameters. They luckily match between all the material-like nodes:
The AmbientColor is an exception. In X3D the effective AmbientColor is an AmbientIntensity * DiffuseColor, thus it has a default value of Source: src/scene/x3d/x3dnodes_utils_materials.inc (line 114). | |

function PureEmissive: boolean; deprecated 'use TUnlitMaterialNode for unlit materials'; |
|
Warning: this symbol is deprecated: use TUnlitMaterialNode for unlit materials Only the emissiveColor is not black (zero), which means that the material behaves like unlit. This checks that ambient and diffuse and specular colors are all zero. It's an important information about the material sometimes. This way of achieving "something like unlit material" has issues, see https://github.com/michaliskambi/x3d-tests/wiki/Why-is-UnlitMaterial-useful . For this reason, we recommend to use (and detect, for optimization) the TUnlitMaterialNode instead of this "special case of Phong material".

function ShininessExp: Single; |
|
Shininess exponent for Phong lighting equations. Remember that the X3D Shininess field is "normalized", which means that it has to be multiplied by 128.0 to get actual exponent for lighting equations. This function returns the real exponent (already multiplied by 128.0, if necessary). Source: src/scene/x3d/x3dnodes_utils_materials.inc (line 151). | |
