Detailed Description

An ImposterSprite is a textured quad which is rendered in place of 3D geometry. The ImposterSprite is generated by rendering the original 3D geometry to a texture as an image cache. The ImpostorSprite is automatically generated by the osgUtil::CullVisitor so it not necessary to deal with it directly.

Member Function Documentation

virtual void osgSim::ImpostorSprite::accept ( Drawable::AttributeFunctor &  af)
virtual

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

virtual void osgSim::ImpostorSprite::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.

virtual void osgSim::ImpostorSprite::accept ( osg::PrimitiveFunctor &  pf) const
virtual

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

Reimplemented from osg::Drawable.

float osgSim::ImpostorSprite::calcPixelError ( const osg::Matrix &  MVPW) const

Calculate the pixel error value for passing in the ModelViewProjectionWindow transform, which transform local coords into screen space.

virtual const char* osgSim::ImpostorSprite::className ( ) const
inlinevirtual

return the name of the node's class type.

Reimplemented from osg::Node.

Definition at line 53 of file ImpostorSprite.h.

virtual osg::Object* osgSim::ImpostorSprite::clone ( const osg::CopyOp &  ) const
inlinevirtual

Clone on ImpostorSprite just returns a clone of type, since it is not appropriate to share data of an ImpostorSprite.

Reimplemented from osg::Node.

Definition at line 50 of file ImpostorSprite.h.

virtual osg::Object* osgSim::ImpostorSprite::cloneType ( ) const
inlinevirtual

Clone an object of the same type as an ImpostorSprite.

Reimplemented from osg::Node.

Definition at line 45 of file ImpostorSprite.h.

virtual osg::BoundingBox osgSim::ImpostorSprite::computeBoundingBox ( ) const
virtual

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

virtual void osgSim::ImpostorSprite::drawImplementation ( osg::RenderInfo &  renderInfo) const
virtual

Draw ImpostorSprite directly.

Reimplemented from osg::Drawable.

osg::Camera* osgSim::ImpostorSprite::getCamera ( )
inline

Get the camera node to use for pre rendering the impostor sprite's texture.

Definition at line 158 of file ImpostorSprite.h.

const osg::Camera* osgSim::ImpostorSprite::getCamera ( ) const
inline

Get the const camera node to use for pre rendering the impostor sprite's texture.

Definition at line 161 of file ImpostorSprite.h.

osg::Vec3* osgSim::ImpostorSprite::getControlCoords ( )
inline

Get the control coordinates of the corners of the quad. The control coordinates are the corners of the quad projected out onto the front face of bounding box which enclosed the impostor geometry when it was pre-rendered into the impostor sprite's texture. At the point of creation/or update of the impostor sprite the control coords will lie on top of the corners of the quad in screen space - with a pixel error of zero. Once the camera moves relative to the impostor sprite the control coords will no longer lie on top of the corners of the quad in screen space - a pixel error will have accumulated. This pixel error can then be used to determine whether the impostor needs to be updated. Stored in the order, [0] - top_left, [1] - bottom_left, [2] - bottom_right, [3] - top_left.

Definition at line 110 of file ImpostorSprite.h.
