Detailed Description

Stores the current depth buffer parameters.

This element stores the current depth buffer parameters used for rendering, including:

• Depth buffer test enabled,
• Depth buffer writing enabled,
• Depth buffer range, and
• Depth comparison function.

Member Enumeration Documentation

enum SoDepthBufferElement::DepthWriteFunction

Depth function mode as defined by OpenGL.

Enumerator:

NEVER	Never passes.
LESS	Passes if the incoming depth value is less than the stored depth value.
EQUAL	Passes if the incoming depth value is equal to the stored depth value.
LEQUAL	Passes if the incoming depth value is less than or equal to the stored depth value.
GREATER	Passes if the incoming depth value is greater than the stored depth value.
NOTEQUAL	Passes if the incoming depth value is not equal to the stored depth value.
GEQUAL	Passes if the incoming depth value is greater than or equal to the stored depth value.
ALWAYS	Always passes.

static void SoDepthBufferElement::get	(	SoState *	state,
		SbBool &	test,
		SbBool &	write,
		DepthWriteFunction &	function,
		SbVec2f &	range
	)			[static]

Returns current depth buffer parameters.

static int SoDepthBufferElement::getClassStackIndex

(

)

[static]

Returns the stack id for this element.

Reimplemented from SoElement.

static SoType SoDepthBufferElement::getClassTypeId

(

)

[static]

Returns the type identifier for this class.

Reimplemented from SoElement.

virtual void SoDepthBufferElement::pop	(	SoState *	state,
		const SoElement *	prevTopElement
	)			[virtual]

Override pop() method to keep GL up to date.

virtual void SoDepthBufferElement::print

(

FILE *

fp

)

const [virtual]

Prints element (for debugging).

Reimplemented from SoElement.

virtual void SoDepthBufferElement::push

(

SoState *

state

)

[virtual]

Override push() method to keep GL up to date.

Reimplemented from SoElement.

static void SoDepthBufferElement::set	(	SoState *	state,
		SoDepthBuffer *	depthBuffer,
		const SbBool	test,
		const SbBool	write,
		const DepthWriteFunction	function,
		const SbVec2f	range
	)			[static]

Sets the depth buffer parameters.

This method will (indirectly) call glDepthMask, glDepthFunc, glDepthRange with the new values

static void SoDepthBufferElement::set	(	SoState *	state,
		const SbBool	test,
		const SbBool	write,
		const DepthWriteFunction	function,
		const SbVec2f	range
	)			[static]

Sets the depth buffer parameters.

This method will (indirectly) call glDepthMask, glDepthFunc, glDepthRange with the new values
