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

virtual void osg::ShapeDrawable::accept ( Drawable::ConstAttributeFunctor af) const [virtual]

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 object's class type.

Must be defined by derived classes.

Reimplemented from osg::Drawable.

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

Clone an object, with Object* return type.

Must be defined by derived classes.

Implements osg::Object.

virtual Object* osg::ShapeDrawable::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::ShapeDrawable::computeBound ( ) const [virtual]

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.

Implements osg::Drawable.

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

Get the color of the shape.

TessellationHints* osg::ShapeDrawable::getTessellationHints ( ) [inline]
const TessellationHints* osg::ShapeDrawable::getTessellationHints ( ) const [inline]
virtual bool osg::ShapeDrawable::isSameKindAs ( const Object obj) const [inline, virtual]

Reimplemented from osg::Drawable.

References NULL.

virtual const char* osg::ShapeDrawable::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.

ShapeDrawable& osg::ShapeDrawable::operator= ( const ShapeDrawable ) [inline, protected]
void osg::ShapeDrawable::setColor ( const Vec4 color)

Set the color of the shape.

void osg::ShapeDrawable::setTessellationHints ( TessellationHints hints)
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.
