Detailed Description

VSG extension Stores the current logical pixel operation for rendering.

This element stores the current logical pixel operation for rendering.

A Logical Operation is a Per-Sample Processing operation applied between the Fragment's color values and color values in the Framebuffer being rendered to that correspond to that particular fragment color. Logical operations are boolean operations performed on the bit pattern that represents the colors.

Member Function Documentation

static void SoLogicOperationElement::get ( SoState state,
bool &  enabled,
LogicOperation operation 
) [static]

get the current logic operation, and wether logic operations are enabled.

Parameters:
state the state from which to retrieve the element instance.
enabled Whether logic operations are enabled
operation which operation is applied
static int SoLogicOperationElement::getClassStackIndex (  )  [static]

Returns the stack id for this element.

Reimplemented from SoElement.

static SoType SoLogicOperationElement::getClassTypeId (  )  [static]

Returns the type identifier for this class.

Reimplemented from SoElement.

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

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

virtual void SoLogicOperationElement::print ( FILE *  fp  )  const [virtual]

Prints element (for debugging).

Reimplemented from SoElement.

virtual void SoLogicOperationElement::push ( SoState state  )  [virtual]

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

Reimplemented from SoElement.

static void SoLogicOperationElement::set ( SoState state,
bool  enable,
LogicOperation  operation 
) [static]

set the current logic operation

Parameters:
state the state from which to retrieve the element instance.
enable Whether to enable or not logic operations
operation which operation to apply
