Unit

X3DNodes

Declaration

type TMaterialNode = class(TAbstractOneSidedMaterialNode)

Description

Material determines how the geometry looks on the screen, by providing parameters to the lighting equations. This is the material responsible for the Phong lighting model.

It specifies how light affects one side of the surface.

Note: Whether the shape is visible from both sides depends on the geometry TAbstractGeometryNode.Solid field, and is independent of whether you use this node or TTwoSidedMaterialNode.

Description

Methods

Public constructor Create(const AX3DName: string = ''; const ABaseUrl: string = ''); override;
 
Public destructor Destroy; override;
 
Public class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;
 
Public function Opacity: Single;

Opacity is just a 1 - FdTransparency.Value. Defined for your comfort — for OpenGL you will usually want to pass Opacity, not Transparency.

Public function ShininessExp: Single;

ShininessExp is just 128 * FdShininess.Value, this is the "real" exponent indicated by shininess field value. Defined for your comfort — for any graphic library you will usually want to pass the "real" exponent given by this function, not just value of shininess field.

Public function MaterialInfo: TMaterialInfo; override;
 
Public function PureEmissive: boolean;

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. It is similar to the NULL material situation (when "Appearance.material=NULL" case), but the color and transparency are still configurable (using FdEmissiveColor and FdTransparency fields).

We can optimize this case when rendering.

Public procedure ForcePureEmissive; deprecated 'use TUnlitMaterialNode for unlit materials';

Warning: this symbol is deprecated: use TUnlitMaterialNode for unlit materials

Force the material pure emissive (see PureEmissive) by setting other colors to black.

Properties

Public property FdAmbientIntensity: TSFFloat read FFdAmbientIntensity;

Internal wrapper for property AmbientIntensity. This wrapper API may change, we advise to access simpler AmbientIntensity instead.

Internal wrapper for property DiffuseColor. This wrapper API may change, we advise to access simpler DiffuseColor instead.

Public property DiffuseColor: TCastleColorRGB read GetDiffuseColor write SetDiffuseColor;

The primary way to control the color of object with Phong material. The object reflects light sources depending on the angle of the surface with respect to the light source. The more directly the surface faces the light, the more diffuse light reflects.

Public property FdDiffuseTexture: TSFNode read FFdDiffuseTexture;

Internal wrapper for property DiffuseTexture. This wrapper API may change, we advise to access simpler DiffuseTexture instead.

Public property DiffuseTexture: TAbstractSingleTextureNode read GetDiffuseTexture write SetDiffuseTexture;

Setting Transparency to value > 0 makes the object partially-transparent. Setting it to 1.0 makes it even invisible (but still collidable).
