Member Function Documentation

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

return the name of the node's class type.

Reimplemented from osg::Node.

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

return a clone of a node, with Object* return type.

Reimplemented from osg::Node.

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

clone an object of the same type as the node.

Reimplemented from osg::Node.

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

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

virtual void osg::DrawPixels::drawImplementation ( 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:
renderInfoThe osg::RenderInfo object that encapsulates the current rendering information including the osg::State OpenGL state for the current graphics context.

Reimplemented from osg::Drawable.

const osg::Image* osg::DrawPixels::getImage ( ) const [inline]
const osg::Vec3& osg::DrawPixels::getPosition ( ) const [inline]
void osg::DrawPixels::getSubImageDimensions ( unsigned int &  offsetX,

unsigned int &  width,

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

return true if this and obj are of the same kind of object.

Reimplemented from osg::Node.

References NULL.

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

return the name of the node's library.

Reimplemented from osg::Node.
