Member Function Documentation

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.

virtual Object* osg::DrawPixels::clone

(

const CopyOp &

copyop

)

const [inline, virtual]

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

Implements osg::Object.

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 BoundingBox osg::DrawPixels::computeBound

(

)

const [virtual]

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

virtual void osg::DrawPixels::drawImplementation

(

State &

state

)

const [virtual]

drawImplementation(State&) 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(State&) is called from the draw(State&) method, with the draw method handling management of OpenGL display lists, and drawImplementation(State&) handling the actuall drawing itself.

Parameters:

state

The osg::State object that encapulates the current OpenGL state for the current graphics context.

Implements osg::Drawable.

const osg::Image* osg::DrawPixels::getImage

(

)

const [inline]

osg::Image* osg::DrawPixels::getImage

(

)

[inline]

const osg::Vec3& osg::DrawPixels::getPosition

(

)

const [inline]

osg::Vec3& osg::DrawPixels::getPosition

(

)

bool osg::DrawPixels::getUseSubImage

(

)

const [inline]

virtual bool osg::DrawPixels::isSameKindAs

(

const Object *

obj

)

const [inline, virtual]

Reimplemented from osg::Drawable.

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.
