Detailed Description

Base class for all Tulip OpenGL entities.

Other Tulip entities inherit for this class.

You don't have to create a GlSimpleEntity, you have to use GlLine, GlRect or GlSphere for example

Member Function Documentation

virtual void tlp::GlSimpleEntity::draw ( float  lod,
Camera camera 
)
pure virtual

Draw function.

Warning
You don't have to call this function, the Tulip OpenGL engine call it.

Implemented in tlp::GlLabel, tlp::GlRect, tlp::GlComplexPolygon, tlp::Gl2DRect, tlp::GlSphere, tlp::GlBox, and tlp::GlGrid.

virtual BoundingBox tlp::GlSimpleEntity::getBoundingBox ( )
inlinevirtual

Return the entity boundingbox.

Warning
You don't have to call this function, the Tulip OpenGL engine call it.

Reimplemented in tlp::GlLabel, and tlp::Gl2DRect.

Definition at line 118 of file GlSimpleEntity.h.

+ Here is the caller graph for this function:

int tlp::GlSimpleEntity::getStencil ( )
inline

Return stencil number of entity.

See also
setStencil()

Definition at line 102 of file GlSimpleEntity.h.

virtual void tlp::GlSimpleEntity::getXML ( std::string &  outString)
pure virtual

Save the entity in outString (in XML format)

Warning
You don't have to call this function, the Tulip OpenGL engine call it.

Implemented in tlp::GlLabel, tlp::GlComplexPolygon, tlp::GlGraphComposite, tlp::GlBox, tlp::GlComposite, tlp::GlSphere, tlp::Gl2DRect, tlp::GlGrid, and tlp::GlCircle.

bool tlp::GlSimpleEntity::isVisible ( ) const
inline

Return if entity is visible.

Definition at line 83 of file GlSimpleEntity.h.

virtual void tlp::GlSimpleEntity::setStencil ( int  stencil)
inlinevirtual

Set stencil number of the entity.

Stencil is an OpenGl system to ensure that other entity can't be displayed above this entity; it's a "guaranted visibility" system. A small number causes a guaranted visibility Default value in Tulip is 0xFFFF (greater integer) And when we have stencil on entity value is 0x2

Reimplemented in tlp::GlComposite.

Definition at line 94 of file GlSimpleEntity.h.

virtual void tlp::GlSimpleEntity::setVisible ( bool  visible)
virtual

Set if entity is visible.

virtual void tlp::GlSimpleEntity::setWithXML ( const std::string &  inString,
unsigned int &  currentPosition 
)
pure virtual

Load entity with inString (in XML format)

Warning
You don't have to call this function, the Tulip OpenGL engine call it.

Implemented in tlp::GlLabel, tlp::GlComplexPolygon, tlp::GlGraphComposite, tlp::GlBox, tlp::GlComposite, tlp::GlSphere, tlp::Gl2DRect, and tlp::GlGrid.
