Member Function Documentation

void diguyOsgGraphicsTextureArray::asynchronous_post_load ( )

virtual

This function will be called by DI-Guy after the texture is loaded but before build.

When asynchronous texture loading is active this provides an opportunity to copy data from DI-Guy structures to end user structures in the background loading thread.

Immediate Mode:

Immediate mode renderers may override this function.

Scene Graph:

Scene graph renderers may override this function, if they are using the async texture loader. may need to be coupled with calls to diguyScenario::run_background_load_update()

Callable From:

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

Reimplemented from diguyGraphicsTextureArray.

void diguyOsgGraphicsTextureArray::build ( )

virtual

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

At that point the texture information has been read from the texture file, and is available via the Accessor Functions above.

Immediate Mode:

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

Scene Graph:

Scene graph renderers usually do override this function, to create an object that gets associated with diguyGraphicsMesh objects.

Callable From:

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

Reimplemented from diguyGraphicsTextureArray.

void diguyOsgGraphicsTextureArray::unbuild ( )

virtual

This function will be called by DI-Guy when it is time for a renderer-specific texture 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 diguyGraphicsTextureArray.

void diguyOsgGraphicsTextureArray::bind_now ( diguyTextureMapType texture_type )

virtual

This function will be called by DI-Guy when the texture should be made active, or bound.

Immediate Mode:

Immediate mode renderers usually do override this function, to invoke the object created by build(), or make calls to the renderer to set appropriate texture state.

Scene Graph:

Scene graph renderers usually do not override this function.

Callable From:

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

Reimplemented from diguyGraphicsTextureArray.
