Castle Game Engine: X3DNodes: Class TAbstractTextureNode

# Class TAbstractTextureNode
Description | Hierarchy | Fields | Methods | Properties
## Unit X3DNodes ## Declaration `type TAbstractTextureNode = class(TAbstractAppearanceChildNode)` ## Description no description available, TAbstractAppearanceChildNode description follows no description available, TAbstractNode description follows Base X3D node. Almost all X3D nodes inherit from this. (Exception: X3DMetadataObject. So you cannot have metadata of metadata of...) ## Hierarchy TPersistent TNonRefCountedInterfacedPersistent TX3DFileItem TX3DNode TAbstractNode TAbstractAppearanceChildNode TAbstractTextureNode ## Overview ### Methods
| `function AlphaChannelData: TAlphaChannel; virtual;`
| `procedure CreateNode; override;`
| `function TextureDescription: string; virtual;`
| `function AlphaChannel: TAlphaChannel;`
### Properties
| `property FdEffects: TMFNode read FFdEffects;`
| `property FdAlphaChannel: TSFString read FFdAlphaChannel;`
## Description ### Methods
| `function AlphaChannelData: TAlphaChannel; virtual;`
Alpha channel detected from image contents (or children nodes), ignoring our FdAlphaChannel field. Actually set only when image data is loaded (e.g. TAbstractTexture2DNode.IsTextureLoaded in case of TAbstractTexture2DNode descendant).
| `procedure CreateNode; override;`
| `function TextureDescription: string; virtual;`
Short description how texture is defined, is it inline or loaded from URL, is it video of simple image texture. "none" if it's not defined at all. Calling this may not cause automatically loading the texture data (for exampe, from file in case of TAbstractTexture2DNode). So it cannot describe the actually loaded data. In this class, simply returns NodeTypeName. Override to say something more descriptive.
| `function AlphaChannel: TAlphaChannel;`
Alpha channel of the loaded texture data. Looks at loaded texture data, and at `alphaChannel` field (see http://castle-engine.sourceforge.net/x3d_extensions.php#section_ext_alpha_channel_detection )
### Properties
| `property FdEffects: TMFNode read FFdEffects;`
| `property FdAlphaChannel: TSFString read FFdAlphaChannel;`
