Detailed Description

DrawPixels is an osg::Drawable subclass which encapsulates the drawing of images using glDrawPixels.

Constructor & Destructor Documentation

osg::DrawPixels::DrawPixels (  ) 

osg::DrawPixels::DrawPixels ( const DrawPixels drawimage,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)

Copy constructor using CopyOp to manage deep vs shallow copy.

virtual osg::DrawPixels::~DrawPixels (  )  [protected, virtual]


Member Function Documentation

virtual Object* osg::DrawPixels::cloneType (  )  const [inline, virtual]

Clone the type of an object, with Object* return type. Must be defined by derived classes.

Implements osg::Object.

virtual Object* osg::DrawPixels::clone ( const CopyOp  )  const [inline, virtual]

Clone an object, with Object* return type. Must be defined by derived classes.

Implements osg::Object.

virtual bool osg::DrawPixels::isSameKindAs ( const Object obj  )  const [inline, virtual]

Reimplemented from osg::Drawable.

References NULL.

virtual const char* osg::DrawPixels::libraryName (  )  const [inline, virtual]

return the name of the object's library. Must be defined by derived classes. The OpenSceneGraph convention is that the namespace of a library is the same as the library name.

Reimplemented from osg::Drawable.

virtual const char* osg::DrawPixels::className (  )  const [inline, virtual]

return the name of the object's class type. Must be defined by derived classes.

Reimplemented from osg::Drawable.

void osg::DrawPixels::setPosition ( const osg::Vec3 position  ) 

osg::Vec3& osg::DrawPixels::getPosition (  )  [inline]

const osg::Vec3& osg::DrawPixels::getPosition (  )  const [inline]

void osg::DrawPixels::setImage ( osg::Image image  )  [inline]

osg::Image* osg::DrawPixels::getImage (  )  [inline]

const osg::Image* osg::DrawPixels::getImage (  )  const [inline]

void osg::DrawPixels::setUseSubImage ( bool  useSubImage  )  [inline]

bool osg::DrawPixels::getUseSubImage (  )  const [inline]

void osg::DrawPixels::setSubImageDimensions ( unsigned int  offsetX,
unsigned int  offsetY,
unsigned int  width,
unsigned int  height 
)

void osg::DrawPixels::getSubImageDimensions ( unsigned int &  offsetX,
unsigned int &  offsetY,
unsigned int &  width,
unsigned int &  height 
) const

virtual void osg::DrawPixels::drawImplementation ( RenderInfo renderInfo  )  const [virtual]

drawImplementation(RenderInfo&) is a pure virtual method for the actual implementation of OpenGL drawing calls, such as vertex arrays and primitives, that must be implemented in concrete subclasses of the Drawable base class, examples include osg::Geometry and osg::ShapeDrawable. drawImplementation(RenderInfo&) is called from the draw(RenderInfo&) method, with the draw method handling management of OpenGL display lists, and drawImplementation(RenderInfo&) handling the actual drawing itself.

Parameters:
renderInfo The osg::RenderInfo object that encapsulates the current rendering information including the osg::State OpenGL state for the current graphics context.

Implements osg::Drawable.

virtual BoundingBox osg::DrawPixels::computeBound (  )  const [virtual]

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

DrawPixels& osg::DrawPixels::operator= ( const DrawPixels  )  [inline, protected]
