Virtual Functions
The functions in this section are all virtual functions that will be called by DI-Guy at various times during DI-Guy execution. Because the functions are all virtual, DI-Guy programmers can create a subclass of this class and override them. Unless otherwise stated, the base class functions do not need to be called.
virtual void	build ()
	This function will be called by DI-Guy when it is time for a renderer-specific state object to be created. More...

Member Function Documentation

diguyGraphicsMaterial* diguyGraphicsState::get_material ( )

This function returns the material of this state.

Specific information about the material can then be accessed from the returned object.

Returns:

object of type diguyGraphicsMaterial; NULL on failure

int diguyGraphicsState::get_num_textures ( )

This function returns the number of textures this state has.

Returns:

number of textures associated with this state

diguyGraphicsTexture* diguyGraphicsState::get_texture ( int texture_index = 0 )

This function returns the nth texture of this state.

Specific information about the texture can then be accessed from the returned object.

Returns:

object of type diguyGraphicsTexture; NULL on failure

diguyTextureMapType diguyGraphicsState::get_texture_type ( int index ) const

This function returns the way that a texture is used in the state.

Possibilities include diffuse, specular, normal.

Returns:

diguyTextureMapType enum

int diguyGraphicsState::get_textures_available ( ) const

This function returns a bit-wise or'ed mask of available textures in this state.

Possibilities include DIGUY_TEXTURE_MAP_MASK_DIFFUSE, DIGUY_TEXTURE_MAP_MASK_SPECULAR, DIGUY_TEXTURE_MAP_MASK_BUMP, etc. See diguyTextureMapMasks enum for a complete list.

diguyGraphicsTextureArray* diguyGraphicsState::get_texture_array ( )

return Decal array

const diguyGraphicsTextureArray* diguyGraphicsState::get_texture_array ( ) const

diguyGraphicsTextureArray* diguyGraphicsState::get_texture_array ( diguyTextureMapType map_type )

return Decal diffuse, specular or normal array

const diguyGraphicsTextureArray* diguyGraphicsState::get_texture_array ( diguyTextureMapType map_type ) const

int diguyGraphicsState::get_contains_alpha_component ( ) const

This function returns whether either the material or texture of this state contains an alpha component.

States that have an alpha component can make objects semi-transparent, which can affect when said objects should be drawn.

Returns:

1 if state contains an alpha component, 0 if not; -1 on failure

int diguyGraphicsState::get_is_unlit ( ) const

This function returns whether faces drawn with this state should be lit or unlit.

Returns:

1 if faces unlit, 0 if lit, -1 on failure

void diguyGraphicsState::free_loader_memory ( )

This function frees most memory allocated by the DI-Guy geometry loader for this object.

This function should only be called during or after the object's build() function has been called. After it has been called, calls to many accessor functions will fail.

virtual void diguyGraphicsState::build ( )

virtual

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

A subclass of this class isn't always necessary, particularly for immediate mode renderers in which everything might be done in a subclass of diguyGraphicsMaterial and a subclass of diguyGraphicsTexture.

Immediate Mode:

Immediate mode renderers usually do not override this function.

Scene Graph:

Scene graph renderers may override this function, to create a state object that will be associated with diguyGraphicsMesh objects.

The subclass version of this function may need to refer to material and texture objects created by the build() calls of subclasses of diguyGraphicsMaterial and diguyGraphicsTexture objects.

Callable From:

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

Reimplemented in diguyOsgGraphicsState.

virtual void diguyGraphicsState::unbuild ( )

virtual

This function will be called by DI-Guy when it is time for a renderer-specific state 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 may 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 in diguyOsgGraphicsState.

virtual void diguyGraphicsState::bind_now ( )

virtual

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

Immediate Mode:

Immediate mode renderers can override this function, but may not need to. The material and texture of the state will receive their own bind_now() calls.

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)

void diguyGraphicsState::bind ( int texture_mask )

Calls bind on internal class which will bind materials and appropriate textures.
