◆ getInstance()

static const SoGLTextureCoordinateElement * SoGLTextureCoordinateElement::getInstance ( SoState * state )

static

The send routines are called on an instance because it is more efficient than calling a static method that looks up the element in the state for every coordinate.

◆ getType()

virtual CoordType SoGLTextureCoordinateElement::getType ( ) const

virtual

Reimplemented from SoTextureCoordinateElement.

◆ init()

virtual void SoGLTextureCoordinateElement::init ( SoState * state )

Reimplemented from SoTextureCoordinateElement.

		SoTextureCoordinateFunctionCB *	func = `NULL`,
		void *	funcData = `NULL`
	)

static

TextureCoordinateFunction nodes that don't use texgen must register a NULL callback to turn off texgen. The texGen arguments point to a function that will issue GL TexGen calls; the func arguments must point to a static function that will return the results of the texgen function (needed because some nodes render by using their generatePrimitives method).
