Detailed Description

Meshes contain the visual geometry of a DI-Guy character.

They are attached to shapes, and are associated with materials and textures.

The class diguyOsgGraphicsMesh is an example of a diguyGraphicsMesh subclass for a scene graph renderer using the DI-Guy Loader. The example subclass shows how to use the accessors of the diguyGraphicsMesh class and which virtual functions should be overridden for a scene graph renderer such as OSG.

Constructor & Destructor Documentation

diguyOsgGraphicsMesh::diguyOsgGraphicsMesh ( void * internal_data )

Member Function Documentation

virtual void diguyOsgGraphicsMesh::build ( )

overridevirtual

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

All information necessary to build the mesh should be available via the Accessor Functions above when this function is called.

Immediate Mode:

Immediate mode renderers may override this function, to create an object that may be invoked by draw().

Scene Graph:

Scene graph renderers usually do override this function, to create a geometry object that gets associated with a diguyGraphicsState object obtained by calling get_state().

Callable From:

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

Reimplemented from diguyGraphicsMesh.

virtual void diguyOsgGraphicsMesh::unbuild ( )

overridevirtual

This function will be called by DI-Guy when it is time for a renderer-specific mesh object 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 diguyGraphicsMesh.

int diguyOsgGraphicsMesh::get_num_drawables ( )

osg::Drawable* diguyOsgGraphicsMesh::get_drawable ( int drawable_index )

void diguyOsgGraphicsMesh::attach_state_set_to_drawable ( int drawable_index )

protected

Looks up the state set for the drawable and attaches the state set to the drawable if not already attached.

Allows for just in time loading of state sets (specifically textures) associated with the drawable.
