nCine::RHI::GS::GsVertexFormat class

Vertex layout description of the GS 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 GS draw dispatch synthesizes sprite corners from the per-draw uniform block and writes general vertex data into GIF packets with its own layout, so the recorded layout is 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.

void SetIbo(const GsBuffer* ibo)

Applies the vertex format (no-op for the GS backend).
void Reset()
Disables all attributes and clears the index buffer.
