Inheritance diagram for VolRenSlab:

VolRenBase Renderable SimBase gutz::Counted List of all members.

Detailed Description

VolRenSlab.h.

Definition at line 25 of file VolRenSlab.h.

Algorithm

Set/Get the rendering algorithm, client strategy

virtual void setAlg (VolRenAlgBase *vrab)
virtual VolRenAlgBaseSP getAlg ()

Slicer

Set/Get the currrent Slicer, client strategy

virtual void setSlicer (VolSlicer *vslice)
virtual VolSlicerSP getSlicer ()

Set/Get sample spacing.

This is in volume model space, which is not the same as texture space.

virtual void setSampleSpace (float sampleSpace)
virtual float getSampleSpace ()

Serialize/un...

virtual std::ostream & saveSelf (std::ostream &os)
 serialize

virtual std::istream & readSelf (std::istream &is)
 unserialize


Draw on/off.

bool isOn () const
void setOn (bool yes)

Delete.

Does this object need to be removed from a render list? This means that the object is finished and anyone with a smart pointer to it needs to delete the smart pointer and stop using the renderable.

bool needsDelete () const
void setDelete (bool yes)

Interaction Functions

Return true if the event was for you.

By default interaction is forwarded to your protected manipulator (_manip). To use it just apply it in your draw function. However, if you don't add any events or call setManipEventsDefault(), you won't have any interaction. Override these functions in your base class to implement custom behaviors.

virtual bool key (unsigned char k, int x, int y)
virtual bool mouse (const gutz::MouseEvent &me)
virtual bool move (const gutz::MouseMoveEvent &mme)

Selected

Is this object currently selected?

virtual void setSelected (bool yes)
bool isSelected () const

Manipulator Interface

gutz::Manip * getManip () const
void setManip (gutz::Manip *const m)
void setManipEventsDefault ()
 you have to call this to enable default interaction, OR customize the manipulators events yourself.


Text object-name

from SimBase

std::string getObjName ()
std::string getName ()
void setName (std::string name)
void setName (const char *name)

Debug prints

from SimBase: These print the object name with the error, mostly for convenience, but they are compiled to inline-no-op if you build in release mode

void derr (const char *when, const char *where=0) const
template<class T> void derr (const char *when, const char *where, const T stuff) const

Modification, AKA "changed"

from SimBase: id based, you can capture the current id for comparison later, if the id's don't match the class has been changed

virtual int getChangeID ()
virtual int getChangeID () const
virtual void setChanged ()
