LegacyGlVertexFormat class
Vertex layout description of the legacy GL 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 legacy GL draw dispatch synthesizes sprite corners from the per-draw uniform block and submits general vertex data with a layout of its own, 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.
Public static variables
-
static std::
uint32_t MaxAttributes constexpr - The maximum number of vertex attributes.
