Member Function Documentation

◆ className()

virtual const char * osg::DrawPixels::className ( ) const
inlinevirtual

return the name of the node's class type.

Reimplemented from osg::Node.

◆ clone()

virtual Object * osg::DrawPixels::clone ( const CopyOp & copyop) const
inlinevirtual

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

Reimplemented from osg::Node.

References DrawPixels().

◆ cloneType()

virtual Object * osg::DrawPixels::cloneType ( ) const
inlinevirtual

clone an object of the same type as the node.

Reimplemented from osg::Node.

References DrawPixels().

◆ computeBoundingBox()

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

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

◆ drawImplementation()

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

Reimplemented from osg::Drawable.
