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

accept() [1/3]

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.

accept() [2/3]

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.

accept() [3/3]

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.

calcPixelError()

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.

className()

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

inlinevirtual

return the name of the node's class type.

Reimplemented from osg::Node.

clone()

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.

cloneType()

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

inlinevirtual

Clone an object of the same type as an ImpostorSprite.

Reimplemented from osg::Node.

computeBoundingBox()

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

virtual

Compute the bounding box around Drawables's geometry.

Reimplemented from osg::Drawable.

drawImplementation()

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

virtual

Draw ImpostorSprite directly.

Reimplemented from osg::Drawable.

getCamera() [1/2]

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

inline

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

getCamera() [2/2]

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

inline

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

getControlCoords() [1/2]

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.

getControlCoords() [2/2]

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

inline

Get the const control coordinates of the corners of the quad.

getCoords() [1/2]

osg::Vec3* osgSim::ImpostorSprite::getCoords ( )

inline

Get the coordinates of the corners of the quad. Stored in the order, [0] - top_left, [1] - bottom_left, [2] - bottom_right, [3] - top_left.

getCoords() [2/2]

const osg::Vec3* osgSim::ImpostorSprite::getCoords ( ) const

inline

Get the const coordinates of the corners of the quad.

getLastFrameUsed()

unsigned int osgSim::ImpostorSprite::getLastFrameUsed ( ) const

inline

Get the frame number for when the ImpostorSprite was last used in rendering.

getParent() [1/2]

Impostor* osgSim::ImpostorSprite::getParent ( )

inline

Get the parent, which is an Impostor.

getParent() [2/2]

const Impostor* osgSim::ImpostorSprite::getParent ( ) const

inline

Get the const parent, which is an Impostor.

getStoredLocalEyePoint()

const osg::Vec3& osgSim::ImpostorSprite::getStoredLocalEyePoint ( ) const

inline

Get the eye point for when the ImpostorSprite was snapped.

getTexCoords() [1/2]

osg::Vec2* osgSim::ImpostorSprite::getTexCoords ( )

inline

Get the texture coordinates of the corners of the quad. Stored in the order, [0] - top_left, [1] - bottom_left, [2] - bottom_right, [3] - top_left.

getTexCoords() [2/2]

const osg::Vec2* osgSim::ImpostorSprite::getTexCoords ( ) const

inline

Get the const texture coordinates of the corners of the quad.

getTexture() [1/2]

osg::Texture2D* osgSim::ImpostorSprite::getTexture ( )

inline

getTexture() [2/2]

const osg::Texture2D* osgSim::ImpostorSprite::getTexture ( ) const

isSameKindAs()

virtual bool osgSim::ImpostorSprite::isSameKindAs ( const osg::Object *  obj ) const

inline

Set the frame number for when the ImpostorSprite was last used in rendering.

setParent()

void osgSim::ImpostorSprite::setParent ( Impostor *  parent )
