Detailed Description

Allow the use of Shapes as Drawables, so that they can be rendered with reduced effort.

The implementation of ShapeDrawable is not geared to efficiency; it's better to think of it as a convenience to render Shapes easily (perhaps for test or debugging purposes) than as the right way to render basic shapes in some efficiency-critical section of code.

Member Function Documentation

Accept a Drawable::ConstAttributeFunctor and call its methods to tell it about the internal attributes that this Drawable has.

Reimplemented from osg::Drawable.

virtual void osg::ShapeDrawable::accept ( PrimitiveFunctor pf) const [virtual]

Accept a PrimitiveFunctor and call its methods to tell it about the internal primitives that this Drawable has.

Reimplemented from osg::Drawable.

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

return the name of the node's class type.

Reimplemented from osg::Node.

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

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

Reimplemented from osg::Node.

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

clone an object of the same type as the node.

Reimplemented from osg::Node.

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

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

Draw ShapeDrawable directly ignoring an OpenGL display list which could be attached.

This is the internal draw method which does the drawing itself, and is the method to override when deriving from ShapeDrawable for user-drawn objects.

Reimplemented from osg::Drawable.

const Vec4& osg::ShapeDrawable::getColor ( ) const [inline]

Get the color of the shape.

virtual bool osg::ShapeDrawable::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::ShapeDrawable::libraryName ( ) const [inline, virtual]

return the name of the node's library.

Reimplemented from osg::Node.

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

Set the color of the shape.

virtual bool osg::ShapeDrawable::supports ( const AttributeFunctor ) const [inline, virtual]

Return false, osg::ShapeDrawable does not support accept(AttributeFunctor&).

Reimplemented from osg::Drawable.

virtual bool osg::ShapeDrawable::supports ( const Drawable::ConstAttributeFunctor ) const [inline, virtual]

Return true, osg::ShapeDrawable does support accept(Drawable::ConstAttributeFunctor&).

Reimplemented from osg::Drawable.

virtual bool osg::ShapeDrawable::supports ( const PrimitiveFunctor ) const [inline, virtual]

Return true, osg::ShapeDrawable does support accept(PrimitiveFunctor&) .

Reimplemented from osg::Drawable.
