Class TMaterialInfo
Unit
Declaration
type TMaterialInfo = class abstract(TObject)
Description
Abstract class for material information, that define material properties for various lighting equations. Particular public descendants define different lighting equations. Particular private descendants map X3D nodes' fields to these parameters.

|
Texture that determines the primary RGB color and transparency (opacity). See TX3DGraphTraverseState.MainTexture, which is really a shortcut to call this. | |

Properties
| Public | property Node: TX3DNode read FNode; |
|
Associated material node. | |
| Public | property Transparency: Single read GetTransparency write SetTransparency; |
|
Transparency of the material determines how much is it "see-through". Value 0 (DefaultTransparency) means fully opaque, 1 means fully transparent. | |
| Public | property Opacity: Single read GetOpacity write SetOpacity; |
|
Opacity of the material, just | |
| Public | property MainColor: TVector3 read GetMainColor write SetMainColor; |
|
Single color that is the best approximation of this material look. For Phong material, it's DiffuseColor. For unlit material, it's EmissiveColor. For physical material, it's BaseColor. This is useful for debug purposes, for example when we force everything to be unlit by Attributes.Lighting=false. It doesn't follow any X3D official equations, it's only for debugging. | |
| Public | property EmissiveColor: TVector3 read GetEmissiveColor write SetEmissiveColor; |
|
Emissive color represents the color of the material that is not affected by any light sources. All material types (unlit, Phong, physical) have this color. | |
