/**
|
||
|
|
* This class gives the ability for a user-friendly way of creating a vertex
|
||
|
|
* declaration for DirectX 9. Since a vertex shader has a fixed input, the
|
||
|
|
* vertex element array can be cached so that a new vertex declaration for
|
||
|
|
* different vertex buffers can be quickly created. Be sure to call
|
||
|
|
* add_end_vertex_element ( ) when finished creating a vertex element array.
|
||
|
|
* VERTEX_ELEMENT_TYPE is used for a simplified mapping of vertex buffer data
|
||
|
|
* to vertex shader inputs. This class is used with DXShaderContext9 and in
|
||
|
|
* conjunction with DXVertexBufferContext9.
