Member Function Documentation

void diguyOsgGraphicsInstanceGroup::build ( )

virtual

This function will be called by DI-Guy when it is time for a renderer specific instance group to be created.

All information to construct the instance group for consumption by either an immediate mode or scene graph renderer is avaiable via the Accessor Functions above when this function is called.

Immediate Mode:

Immediate mode renderers do not usually override this function.

Scene Graph:

Scene graph renderers override this function to create scene graph specific objects to handle mangement and rendering of the instance group.

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Build Stage)

Reimplemented from diguyGraphicsInstanceGroup.

void diguyOsgGraphicsInstanceGroup::unbuild ( )

virtual

This function will be called by DI-Guy when it is time for a instance group to be destroyed.

Immediate Mode:

Immediate mode renderers may override this function, to destroy any object that may have been created by build().

Scene Graph:

Scene graph renderers usually do override this function, to destroy any object that may have been created by build().

Callable From:

N/A (automatically called by DI-Guy Graphics API during the Unbuild Stage)

Reimplemented from diguyGraphicsInstanceGroup.

void diguyOsgGraphicsInstanceGroup::update ( )

virtual

This function will be called by DI-Guy when it is time for the instance group to be updated with new data.

Immediate Mode:

Immediate mode renderers usually do not override this function.

Scene Graph:

Scene graph renderers should override this function if they are supporting instancing.

Callable From:

N/A (automatically called by DI-Guy Graphics API during Update Stage)

Reimplemented from diguyGraphicsInstanceGroup.
