Member Function Documentation

virtual void vrj::DrawManager::draw (    )  [pure virtual]
 

Enable a frame to be drawn.

Takes a jccl::Configuration and extracts API-specific stuff.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::sync (    )  [pure virtual]
 

Blocks until the end of the frame.

Postcondition:
The frame has been drawn.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::setApp (  App *    app )  [pure virtual]
 

Sets the application with which the Draw Manager will interact.

Note:
The member variable is not in the base class because its "real" type is only known in the derived classes.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::initAPI (    )  [pure virtual]
 

Initializes the drawing API (if not already running).

Note:
If the draw manager should be an active object, start the process here.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::addDisplay (  Display *    disp )  [pure virtual]
 

Callback when display is added to Display Manager.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::removeDisplay (  Display *    disp )  [pure virtual]
 

Callback when display is removed to Display Manager.

Implemented in vrj::GlDrawManager.

virtual void vrj::DrawManager::closeAPI (    )  [pure virtual]
 

Shuts down the drawing API.

Note:
If it was an active object, kill process here.

Implemented in vrj::GlDrawManager.

void vrj::DrawManager::setDisplayManager (  DisplayManager *    dispMgr ) 
 

Setter for Display Manager variable.
