Member Function Documentation

virtual void osg::Geometry::accept ( Drawable::AttributeFunctor af)
virtual

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

Reimplemented from osg::Drawable.

virtual void osg::Geometry::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::Geometry::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 void osg::Geometry::accept ( PrimitiveIndexFunctor 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.

void osg::Geometry::addElementBufferObjectIfRequired ( osg::PrimitiveSet primitiveSet)
protected
bool osg::Geometry::addPrimitiveSet ( PrimitiveSet primitiveset)

Add a primitive set to the geometry.

void osg::Geometry::addVertexBufferObjectIfRequired ( osg::Array array)
protected
bool osg::Geometry::areFastPathsUsed ( ) const
inline

Return true if OpenGL fast paths will be used with drawing this Geometry.

Fast paths directly use vertex arrays, and glDrawArrays/glDrawElements so have low CPU overhead. With Slow paths the osg::Geometry::drawImplementation has to dynamically assemble OpenGL compatible vertex arrays from the osg::Geometry arrays data and then dispatch these to OpenGL, so have higher CPU overhead than the Fast paths. Use of per primitive bindings or per vertex indexed arrays will drop the rendering path off the fast path.

Get the index number of a primitive set, return a value between 0 and getNumPrimitiveSet()-1 if found, if not found then return getNumPrimitiveSet().

When checking for a valid find value use if ((value=geometry->getPrimitiveSetIndex(primitive))!=geometry.getNumPrimitiveSet())
