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, and vrj::PfDrawManager.

Referenced by vrj::Kernel::controlLoop().

virtual void vrj::DrawManager::sync

(

)

[pure virtual]

Blocks until the end of the frame.

Postcondition:

The frame has been drawn.

Implemented in vrj::GlDrawManager, and vrj::PfDrawManager.

Referenced by vrj::Kernel::controlLoop().

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, and vrj::PfDrawManager.

Referenced by vrj::Kernel::startDrawManager().

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, and vrj::PfDrawManager.

Referenced by vrj::Kernel::startDrawManager().

virtual void vrj::DrawManager::addDisplay

(

Display *

disp

)

[pure virtual]

Callback when display is added to Display Manager.

Implemented in vrj::GlDrawManager, and vrj::PfDrawManager.

Referenced by vrj::DisplayManager::setDrawManager().

virtual void vrj::DrawManager::removeDisplay

(

Display *

disp

)

[pure virtual]

Callback when display is removed to Display Manager.

Implemented in vrj::GlDrawManager, and vrj::PfDrawManager.

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, and vrj::PfDrawManager.

Referenced by vrj::Kernel::stopDrawManager().

void vrj::DrawManager::setDisplayManager

(

DisplayManager *

dispMgr

)

Setter for Display Manager variable.

Definition at line 40 of file DrawManager.cpp.
