- Description
- ===========
- The VertexBlend sample demonstrates a technique called vertex blending (also
- known as surface skinning). It displays a file-based object which is made to
- bend is various spots.
-
- Surface skinning is an impressive technique used for effects like smooth
- joints and bulging muscles in character animations.
-
- Note that not all cards support all features for vertex blending. For more
- information on vertex blending, refer to the DirectX SDK documentation.

- Programming Notes
- =================
- Vertex blending requires each vertex to have an associated blend weight.
- Multiple world transforms are set up using SetTransformState() and the
- blend weights determine how much contribution each world matrix has when
- positioning each vertex.
-
- In this sample, a mesh is loaded using the common helper code. What is
- important is how a custom vertex and a custom FVF is declared and used
- to build the mesh (see the SetFVF() call for the mesh object). Without
- using the mesh helper code, the technique is the same: just create a
- vertex buffer full of vertices that have a blend weight, and use the
- appropriate FVF.
-
- This sample makes use of common DirectX code (consisting of helper functions,
- etc.) that is shared with other samples on the DirectX SDK. All common
- classes and modules can be found in the following directory:
