Member Function Documentation

◆ acquireBits()

static uint32_t SoStencilBitsElement::acquireBits	(	SoState *	state,
		SoNode *	node,
		int	num
	)

static

This returns a mask of the acquired bits or 0x0 if there are not enough stencil bits available.

◆ clearBitsInUse()

static void SoStencilBitsElement::clearBitsInUse ( SoState * state )

static

This is required e.g. for framebuffer objects which use the same GL context but have a different stencil buffer. In that case the currently aquired stencil bits are not valid for this buffer. The programmer must then clear the used stencil bits of the element.
