Description

Methods

Public procedure CreateNode; override;
 
Public destructor Destroy; override;
 
Public class function ClassX3DType: string; override;
 
Public function AmbientColor3Single(MatNum: integer): TVector3Single;

Easily extract VRML 1.0 material properties. These methods secure you from accessing non-existing material index (will return the last existing value, or default value if field is empty).

Functions returning TVector4Single add Opacity at the last component.

Transparency and Opacity are in [0 .. 1] range. Opacity = 1 - Transparency.

ShininessExp is the not normalized shininess exponent for Phong lighting equations. Normal VRML/X3D shininess field is "normalized", that is it has to be multiplied by 128 to get actual exponent for lighting equations.

Public function Mirror(MatNum: integer): Single;
 
Public function ReflSpecularExp (MatNum: integer): Single;
 
Public function TransSpecularExp(MatNum: integer): Single;
 
Public function PureEmissive: boolean;

Only the emissive color is not black (zero). This detects a special case described in VRML 1.0 specification: when ambient, diffuse and specular are all empty (no values), then emissiveColor should be used at the final color and shape should be unlit.

You should use the EmissiveColor4Single in this case.

Public procedure ForcePureEmissive;

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

Public class function ForVRMLVersion(const Version: TX3DVersion): boolean; override;
 
Public function MaterialInfo: TMaterialInfo;

Material information based on this node. It is automatically updated when properties of this material change. Do not free it yourself, it will be automatically freed when this node is freed.
