Unit

type TglBitmapCubeMap = class(TglBitmap2D)

wrapper class for cube maps (OpenGL target = GL_TEXTURE_CUBE_MAP) all operations on a bitmap object must be done from the render thread

	`procedure AfterConstruction; override;`
	`procedure UploadData(const aDataObj: TglBitmapData; const aCheckSize: Boolean = true); override;`
	`procedure UploadCubeMap(const aDataObj: TglBitmapData; const aCubeTarget: Cardinal; const aCheckSize: Boolean);`
	`procedure Bind( const aEnableTextureUnit: Boolean = true); reintroduce; virtual;`
	`procedure Unbind( const aDisableTextureUnit: Boolean = true); reintroduce; virtual;`

	`procedure AfterConstruction; override;`
this method is called after constructor and initializes the object

procedure UploadData(const aDataObj: TglBitmapData; const aCheckSize: Boolean = true); override;

upload texture data from given data object to video card

aData: texture data object that contains the actual data
aCheckSize: check size before upload and throw exception if something is wrong

procedure UploadCubeMap(const aDataObj: TglBitmapData; const aCubeTarget: Cardinal; const aCheckSize: Boolean);

upload texture data from given data object to video card

aData: texture data object that contains the actual data
aCubeTarget: cube map target to upload data to (e.g. GL_TEXTURE_CUBE_MAP_POSITIVE_X)
aCheckSize: check size before upload and throw exception if something is wrong

procedure Bind( const aEnableTextureUnit: Boolean = true); reintroduce; virtual;

bind texture

procedure Unbind( const aDisableTextureUnit: Boolean = true); reintroduce; virtual;

unbind texture
