List of all members.

Public Member Functions

• virtual void environment_render (VRenderContext &Context) const =0

  A render routine which may change the state of OpenGL for all subsequent renderings.
  

• virtual void environment_render (VRenderContext &Context, double Z, double dZ) const
• virtual RefPtr< BoundingBall > getBoundingBall (const RefPtr< ValuePool > &VP) const

  Retrieve the bounding volume of the object.
  

• bool isVisible (const RefPtr< ValuePool > &Context) const

  Check visibility of the given render object relative to a give Context.
  

• bool safe_render (VRenderContext &Context, double Z=0, double dZ=-1) const

  Calls the render function with pushing/popping the modelview matrix.
  

• bool timed_render (double &RenderTime, VRenderContext &Context, double Z=0, double dZ=-1) const

  Render this object (calling safe_render() ) including timing measurements.
  

Static Public Member Functions

• static const char * VisibilitySlotName ()

  The name of the slot indicating visibility.
  

Public Attributes

• VOutput< double > RenderTime
• VOutput< double > RenderTimeContribution

  Contribution of this object's rendering time to the overall scene. If the render precision is smaller than 1.0 and this value is large, then this object should really do something to become faster.
  

Protected Member Functions

• RenderAble (const string &name, int p, const RefPtr< VCreationPreferences > &VP)

  constructor, does nothing.
  

• virtual ~RenderAble ()=0

  virtual destructor
  

Protected Attributes

• TypedSlot< bool > Visibility

  Object visibility.

virtual void Wizt::RenderAble::environment_render

(

VRenderContext &

Context

)

const [pure virtual]

A render routine which may change the state of OpenGL for all subsequent renderings.

Use this function overload with care! By default, it saves the OpenGL state, calls the render() routine, and restores the OpenGL state.

Implemented in Wizt::VGLRenderObject, CameraLens, and LocalLens.

RefPtr< BoundingBall > Wizt::RenderAble::getBoundingBall

(

const RefPtr< ValuePool > &

VP

)

const [virtual]

Retrieve the bounding volume of the object.

By default, it reads out the interface of the local VObject::State object.

Reimplemented in Wizt::VRenderObject.

bool Wizt::RenderAble::safe_render	(	VRenderContext &	Context,
		double	Z = 0,
		double	dZ = -1
	)		const

Calls the render function with pushing/popping the modelview matrix.

Parameters:

Z	The starting depth
dZ	The depth thickness; if negative, draw all.

Note:

Use the timed_render() function in application code. This function will throw render exceptions if something bad happened during rendering.

bool Wizt::RenderAble::timed_render	(	double &	RenderTime,
		VRenderContext &	Context,
		double	Z = 0,
		double	dZ = -1
	)		const

Render this object (calling safe_render() ) including timing measurements.

This is the preferred methods on how objects are rendered. This function will catch exceptions and print them on the console, so it is safe to call. If an application wants to do something about render exceptions, then do not call this function but use safe_render() instead.

const char * Wizt::RenderAble::VisibilitySlotName

(

)

[static]

The name of the slot indicating visibility.

This name is a reserved name for child classes, they must not defined own slots of same name.
