Module screen_13::gpu::vertex

Screen 13 offers a number of vertex formats for use loading models.

Additional vertex formats will be released to support new features in the future.

Model Vertices

There are two main flavors of model vertex:

• Normal (POSITION and TEXCOORD only)
• Skinned (for animation - includes JOINTS and WEIGHTS attributes)

Further, vertexes may be specified in the standard manner mentioned above or using the Ex-variety structs. Extended model vertices include the NORMAL and TANGENT attributes which are normally calculated at runtime.

NOTE: Extended vertices are only needed if you want more control over the normal/tangent generation process.

Structs

NormalVertex	The "easy" vertex. If you are not sure what you want, this is probably it.
NormalVertexEx	Same as Normal, except that the additional vertex attributes (normal and tanget) are specified here as opposed to being calculated before use.
SkinVertex	Same as Normal, except that additional vertex attributes for joins and weights are added.
SkinVertexEx	Like NormalEx, a combination of Skin and extra normal and tangent vertex attributes.

Enums

Vertex

Defines all supported vertex formats.
