Member Function Documentation

const SbVec4f& SoTextureCoordinateElement::get	(	const SbVec3f &	point,
		const SbVec3f &	normal
	)		const

Given point and normal, returns texture coordinate. (The r coordinate will be 0.0 and the q will be 1.0 until we get 3D texture coordinate functions.)

const SbVec2f& SoTextureCoordinateElement::get2 ( int index ) const

const SbVec4f& SoTextureCoordinateElement::get4 ( int index ) const

static const SoTextureCoordinateElement* SoTextureCoordinateElement::getInstance ( SoState * state ) [static]

The get 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.

Reimplemented in SoGLTextureCoordinateElement.

int32_t SoTextureCoordinateElement::getNum ( ) const [inline]

Returns the number of coordinate points in an instance.
