Description

Methods

Protected procedure LoadTextureData; virtual; abstract;

This does the actual loading of texture data.

You can assume here that texture is not loaded now, UsedCache, FTextureImage, FTextureComposite are all nil. Try to load the texture data, making WritelnWarning as appropriate, and set all UsedCache, FTextureImage, FTextureComposite, FAlphaChannelData.

Public property FdRepeatS: TSFBool read FFdRepeatS;
 
Public property FdRepeatT: TSFBool read FFdRepeatT;
 
Public property FdRepeatR: TSFBool read FFdRepeatR;
 
Public property FdTextureProperties: TSFNode read FFdTextureProperties;
 
Public property TextureProperties: TTexturePropertiesNode read GetTextureProperties write SetTextureProperties;

Texture properties (how the texture behaves when sampled, and such).

Public property TextureLoaded: boolean read FTextureLoaded write SetTextureLoaded;

Load and unload 3D texture.

When loading, we will try to set TextureImage and TextureComposite. If loading is successful, TextureImage will be always set to non-nil (TextureComposite will be set to non-nil only if image came from some composite (DDS, KTX...) image). If loading failed, both TextureImage and TextureComposite will be Nil.

Note that even when loading failed (TextureImage remained Nil), TextureLoaded value still changes to True. This is good — it makes assignment TextureLoaded := true always work, and (more important) it prevents trying to load (and displaying uselessly the same WritelnWarning) again at successful TextureLoaded := true.

In case of problems (for example when some URL cannot be loaded), we will make WritelnWarning.
