SoShapeStyleElement Class Reference

This elements stores some information shapes need to quickly determine whether or not they should render, and, if they should render, how they should render. More...

List of all members.

Public Member Functions
SbBool	mightNotRender () const
	Returns TRUE if shapes may not render for some reason:
SbBool	needNormals () const
	Returns TRUE if need normals:
SbBool	needTexCoords () const
	Returns TRUE if need texture coordinates:
int	getRenderCaseMask () const
	Returns a mask that can be used by the SoVertexPropertyCache class (see SoVertexProperty.h for the SoRenderInfo class) to quickly mask out the normal or texture coordinate cases if normals or texture coordinates aren't needed.
SbBool	isTextureFunction () const
virtual void	init (SoState *state)
	Initializes element.
virtual SbBool	matches (const SoElement *elt) const
	Returns TRUE if the element matches another element (of the same class, presumably) with respect to cache validity.
virtual void	push (SoState *state)
	Pushes/pops element.
virtual SoElement *	copyMatchInfo () const
	Create a copy that we can put in a cache used list and call matches() on later.
virtual void	print (FILE *fp) const
	Prints element (for debugging)
Static Public Member Functions
static const SoShapeStyleElement *	get (SoState *state)
	API USED BY SHAPES:
static void	setDrawStyle (SoState *state, int32_t value)
	API USED BY OTHER ELEMENTS:
static void	setComplexityType (SoState *state, int32_t value)
static void	setTransparencyType (SoState *state, int32_t value)
static void	setTextureEnabled (SoState *state, SbBool value)
static void	setTextureFunction (SoState *state, SbBool value)
static void	setLightModel (SoState *state, int32_t value)
static void	setOverrides (SoState *state, SbBool value)
	Set value is TRUE if either diffuse, transparency, or materialbinding are overridden; otherwise FALSE.
static SbBool	isScreenDoor (SoState *state)
static void	initClass ()
	Initializes the SoElement class.

Detailed Description

Specifically, it stores:

NeedNormals: TRUE if lighting is on NeedTexCoords: TRUE if texturing and texcoords not generated by GL

MightNotRender: TRUE if: -- bounding box complexity -- invisible drawstyle -- render abort callback registered
