SwVertexFormat class
Vertex layout description of the software backend (aliased as RHI::VertexFormat).
Records the set of vertex attributes (component count, type, stride, offset and source buffer) the way the OpenGL backend does, so the pipeline's attribute setup code compiles unchanged. The software effects that reproduce the sprite/tile shaders synthesize their corners from the draw index and read per-draw data from uniforms, so the recorded layout is currently informational — Define() and Reset() have nothing to apply.
Public types
- class Attribute
- A single vertex attribute within a vertex format.
