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.

diguyOsgGraphicsMesh::diguyOsgGraphicsMesh ( void * internal_data )

Member Function Documentation

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.

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.
